63 Figure 4.4: Avoid the risk of contamination without ensuring food hygiene and safety .... To assess the current situation of food hygiene and safety at the company in order to find me
INTRODUCTION
Research rationale
Food is an indispensable and most important human need Nowadays, with economic development and improved living standards, people's food needs are increasingly demanding, especially in terms of quality and ensuring hygiene and safety ( 1 )
The kitchen is a processing and cooking facility for a group of people to eat together and customers on the spot Currently, the demand for food processed in the kitchen is great because of its convenience to consumers, managers and suitable to the needs of the community ( 2 )
Food poisoning in the kitchen often happens suddenly, with a large number of people eating together, causing little death but affecting health and public opinion Food used in the kitchen is often mixed food, so determining the cause is difficult The cause of gastroenteritis in the kitchen is usually diagnosed clinically and epidemiologically ( 3 )

LITERATURE REVIEW
Food and food safety
Food is food and drink in processed or unprocessed form that humans can eat and drink with the basic purpose of providing nutrients necessary for the body to maintain organ functions Thereby, people can live and work Food safety was defined in 1893 by the Joint Committee of Experts of the World FAO (Food Agriculture Organization) and the World Health Organization (WHO) as: “All conditions and conditions Necessary measures are applied in the process of production, processing, preservation and circulation of food to ensure safety for users ( 4 )
Health and food have a close relationship with each other, a small change in food can also have an impact on health that can be good or bad Quality control of food hygiene and safety is becoming more and more important and urgent
Food hygiene and safety is to ensure the whole food supply chain from the selection of seedlings, soil, water, methods of care, collection and transportation of food to consumers Any step in the food supply chain that is not secure will lead to unsafe food for human consumption Food safety is not only in the perception that buyers know how to choose and use safe food People who directly produce food sources must be aware of everyone's lives as well as their own.( 11 ) Food needs to be safe before reaching users, in order to minimize the risk of danger The risk of food poisoning, especially the collective poisoning of many collective kitchens
Figure 2.1: Ensuring food hygiene and safety from hand washing
Currently, the state of chemical contamination of plant protection drugs, the problem of chemical residues, microorganisms, preservatives, growth hormones on agricultural products, vegetables, fruits, meat, etc is a very pressing situation
According to the director of the Department of Food Safety and Hygiene:
"We have to look directly at the situation that our country's agriculture is still fragmented, most of it is done on the model of four small farmers, so the synchronous investment from seed, plants and animals to apply farming methods, raising according to standards to ensure food safety such as GAP, HACCP is still limited Therefore, when checking the food hygiene and safety criteria of products circulating on the market , there are still residues of pesticides exceeding the allowable limit, in vegetables accounting for 11.65-13%, in fruits from 5-15.15% (4)
Unhygienic eating and drinking are the cause of food poisoning Food substances, manifested by stomach and intestinal symptoms (abdominal pain, nausea, diarrhea ) or other symptoms depending on the cause of the toxicity A food poisoning case is defined as when at least two people are infected by eating the same food at the same time, according to the new point of view of the Food Hygiene and Safety Department, a food poisoning case is also understood when only one person eats it, but the person died from ingesting that food The causes of food poisoning are also divided into different groups by countries In Vietnam, currently divided into 4 main groups of causes as follows:
Poisoning by eating food contaminated with microorganisms, toxins of bacteria, viruses, parasites, toxic molds:
Caused by molds and mycotoxins: the most common is aflatoxin mycotoxins
Poisoning due to malformed food, rancid food:
Poisoning due to stale, metamorphosed food: most common in protein- rich foods
Poisoning due to allergies to metabolic intermediates from food:
Poisoning due to rancid grease
Poisoning because the food itself contains poison
Animals and plants contaminated with chemicals
Due to heavy metal contamination,
For food poisoning to occur, first of all, pathogenic bacteria must infect the food under the following conditions:
The environment is not hygienic
Lack of hygiene during processing, personal hygiene is not guaranteed
Cattle and poultry themselves were sick
Food poisoning usually manifests in two forms: acute poisoning and chronic poisoning Acute poisoning is usually caused by eating foods contaminated with chemicals in large amounts, chemicals that are highly toxic to humans or pathogenic microorganisms with high toxicity, in large quantities, manifested by rampant symptoms and high mortality Chronic poisoning is latent, it is the iceberg in the population In which toxic substances of chemical origin can accumulate in parts of the body, affecting the metabolism of substances, sometimes these toxins lead to genetic modification and cause cancer, some dangerous diseases such as tumors Many studies have shown that diet is closely related to cancer, especially in the present time, when business people are using rampant chemicals and toxic additives
Current status of industrial kitchens at home and abroad
2.2.1.Food safety in the world
Food is a daily necessity of human beings It is thanks to food that humans every day in many countries around the world, and millions of people have become ill and die from eating unsafe food
According to statistics of the World Health Organization (WHO), there are currently 400 unsafe food-borne diseases, mainly cholera, typhoid, diarrhea, influenza Food hygiene and safety have been put on top at many global health and public health conferences, but the situation has not improved much Every year, around the world, 1.3 billion people suffer from diarrhea, of which 70% are caused by unsafe food use, in developing countries of the population are infected with worms, up to 60% of food poisoning cases and unsafe food containing toxic chemicals is responsible for 35% of cancers in poor countries.( 5 )
2.2.2 Food hygiene and safety in Vietnam today
Currently, the management of food production, processing and supply in our country has not been done well, so there is still a potential risk of many unsafe foods for consumers
A large amount of animal viscera, seafood has begun to decompose, give off an unpleasant smell, but have been cleaned with chemicals to sell to consumers Tens of tons of rancid, stinking animal fat are processed into water fat provided to processing facilities, purified water bottled with bacteria, soft drinks prepared with borehole water Porridge nutrition and the use of sodium benzoate in food for children Fresh fruits and vegetables sold on the stalls mostly do not have food safety certificates and are of unknown origin.( 7 )
According to statistics of the Ministry of Health, in the first four months of 2016 alone, nearly 30 cases of serious poisoning occurred nationwide, causing over 1,386 people to be poisoned, of which 2 died poisoning caused by eating food contaminated with microorganisms caused by hot weather, along with some cases of poisoning due to absorption of residual chemicals in food (2)
Food poisoning in collective kitchens, industrial kitchens, restaurants, establishments, factories and companies with poor workers is also a hot and alarming problem Workers were poisoned by eating dirty food, contaminated food, etc According to the provincial Food Safety and Sanitation Sub- department, in 2015 there were 6 cases of food poisoning in Vinh Phuc, of which 5 occurred in kitchens collective eating in industrial zones caused nearly 90 workers to be hospitalized From the beginning of 2016 until now, there has been a case of food poisoning at BH Vina Co., Ltd - Khai Quang Industrial Park, causing 22 workers after eating galangal fried scad containing Histamine toxin exceeding the permissible threshold, leading to abdominal pain, Diarrhea requires hospitalization.( 6 )
Hazard control system HACCP
2.3.1.Theoretical basis 2.3.1.1 Some basic concepts
HACCP stands for Hazard Analysis and Critical Control Points which means the system of hazard analysis and determination of critical control points.(5)
The HACCP system: This is a scientific, rational and systematic approach to hazard identification, identification and control in the manufacture, processing, manufacturing, preparation and use of food products to ensure that the food is safe to consume
Critical Control Points: Points, stages or processes at which an acceptable hazard can be controlled and prevented, eliminated or reduced (16 )
Primary Food Hazards and Hazards : A hazard is defined as a biological, chemical or physical agent or condition in food that has the potential to cause adverse health consequences A more significant threat facing the food industry today are microbiological contaminants, such as Salmonella, E.coli 0157:H7, Lysteria, Compylobacter ( 8 )
Figure 2.3: Hazard Analysis and Critical Control Points Certified 2.3.1.2.Features of HACCP
Systematic: HACCP reviews and controls all steps in the production, processing or supply of food Helps identify hazards, develop and apply controls, and verify system effectiveness to ensure safety is maintained
Scientific basis: Safety hazards for a food and their control are determined based on scientific evidence
Prevention: HACCP is more about prevention than inspection when the product is finished
Always relevant: When there is a change in facilities, technology, people, and food safety information, the system is always reviewed and adjusted accordingly
2.3.2 Assessment of food hygiene and safety according to HACCP 2.3.2.1 Benefits of applying HACCP
The HACCP system is a preventive management system that focuses on controlling critical, critical points on a scientific basis, reliable practice (hazard analysis and assessment process) and monitoring measures Effective monitoring and control helps to minimize the level of risk to food safety.( 9 )
The fact has proven that countries with strict control policies on food hygiene and safety will significantly reduce production costs and take care of public health In order to ensure food safety and hygiene in developed countries such as the US, Canada, Japan, the European Union, etc., it is mandatory to apply the hazard analysis system and critical control point HACCP in the domestic food processing industry and imported food.( 10 )
The establishment and application of the HACCP system for food production and trading enterprises will bring benefits such as:
Reduce the risk of food poisoning and food-borne illnesses Increased confidence in food supply and consumption Improving quality of life: health, economy and society
Improve the quality reputation for their products, increase their
Helping businesses improve their ability to manage food safety, improve production processes and improve the natural environment
It is a condition for enterprises to conduct self-declaration of food hygiene and safety standards, serving as a basis for food safety and quality inspection agencies to consider the reduced inspection regime and is the basis of the training investment priority policy of the State as well as foreign partners
2.3.2.2.Current status of application of the HACCP system
Food hygiene and safety is a top concern, especially in collective kitchens that serve many people at the same time such as restaurant kitchens, hotels, hospitals, kindergartens or kitchens in kitchens factories, this issue should be given due attention ( 8 )
In recent years, the situation of food hygiene and safety in Vietnam is at an alarming state The situation of food processing is not in accordance with the composition of raw materials as well as technological processes and equipment in processing and serving of industrial kitchens that are not guaranteed food hygiene and safety, causing a series of problems An unfortunate mass poisoning incident occurred ( 9)
According to the Department of Food Hygiene and Safety of the Ministry of Health, in Vietnam there are more than 256 industrial zones, there are nearly 1000 cases of collective poisoning / 1 year
In 2011: 47,000 people were poisoned, 56.5% of industrial kitchens In 2012: 3,663 people were poisoned, 68.1% from industrial kitchens
In 2014: 2,318 people were poisoned, 41% from industrial kitchens Food hygiene and safety in the country in general and the city in particular are creating many worries for workers.
Kitchen and food safety hazards
In the process of producing, processing, transporting and preserving food, if safety and hygiene regulations are not strictly followed, there may be risks of food contamination
It should be noted that they are only called “hazards”, when such conditions or impurities in food can cause disease or harm to human health and only those hazards need to be controlled in the process of producing, processing, preserving and transporting food.( 10 )
There are 3 types of food contamination hazards: biological hazards, physical hazards and chemical hazards
Biological hazards include: bacteria, viruses and parasites
A Pathways of biological contamination of food
Unsanitary conditions, no cover, flies,
B Biological agents that contaminate food a) The risk of contamination by bacteria
Bacteria are the most common of all food contamination hazards
According to statistics, 50-60% of food poisoning cases in Vietnam are caused by bacteria
Bacteria are everywhere, especially feces, sewage, garbage, fresh food dust, which are reservoirs of many types of disease-causing bacteria Even in the human body, there are many types of bacteria, they reside in the skin, hands, mouth, respiratory tract, digestive tract, genitals, and urinary tract.( 10 )
Bacteria reproduce by duplication, the rate of multiplication and survival of bacteria depends on many factors such as oxygen, temperature, humidity, acidity
Under the right conditions, bacteria reproduce very quickly, can doubles in 20 minutes, from one bacterium after 8 hours it will multiply to approximately 17,000,000 Most bacteria can survive and grow at 10-60°C and are killed at boiling point (100°C) The temperature between 25-45°C is very favorable for most bacteria in food to grow, which is dangerous, so cooked food should be eaten immediately, should not be left at room temperature for more than 2 hours At cold temperatures (below 3°C) most bacteria do not reproduce, if any, very slowly (note that some bacteria can still multiply at 3-10°C) ( 11) In freezing conditions, most bacteria cannot reproduce Boiling and pasteurizing kills bacteria in minutes However, some bacteria have spores or heat-resistant toxins secreted by some bacteria that may not be destroyed or destroyed at boiling temperature
Table 2.1: Temperature kills bacteria in food
Booking water temperature (100 degrees celsius) Cooking to this temperature will kill most bacteria Hot temperature
Prevents the growth of bacteria Dangerous temperature range Temperatures in this range allow bacteria to multiply quickly, including bacteria that cause food poisoning
Refrigerator temperature Food poisoning bacteria cannot reproduce at this temperature
Frozen temperature Freezing temperature stops any bacterial growth b) The danger of contamination by viruses
Viruses are many times smaller than bacteria, and must be magnified tens of thousands of times using a microscope to see them In general, viruses can withstand cold, not heat and ultraviolet rays Viruses are affected by disinfectants such as formol, alcohol, strong acids and alkalis Viruses that cause food poisoning and food-borne illnesses are commonly found in the human gut
Infectious species living in contaminated water, watered vegetables with feces or raw dishes prepared in unsanitary conditions are often infected with polio virus, hepatitis virus The virus can be transmitted from faeces through hand contact or from fecal-contaminated water into food In very small amounts, the virus infects people Human viruses can be transmitted to food or directly to other people before becoming sick c) The parasites Parasites are living organisms (parasites) in the body of other living organisms (hosts), taking food from those organisms to survive and develop
Most parasites die and lose their pathogenicity at 15°C The common parasites in food are worms and flukes.( 11 )
Tapeworms: Meat-eaters have tapeworm larvae in beef, in uncooked pork (rice pork), when entering the body, the larvae will develop into adult flukes and parasites in the intestinal tract, causing digestive disorders
Liver fluke: When eating freshwater fish such as carp, drifting fish, perch there are small liver fluke cysts that have not been cooked thoroughly, the cysts move up the bile duct, to the liver and develop in the liver Adult flukes cause liver and bile damage
Lung fluke: If you eat shrimp or crab with cysts of lung fluke larvae, have not been cooked well or drink unclean water with cysts, they will penetrate the intestinal wall, pass through the diaphragm to the lungs, and develop into a lung fluke Adult flukes cause bronchitis, chest pain, cough, and spit up blood, which is very dangerous
Diseases caused by helminths: due to the habit of eating rare meat, spring rolls with raw meat, eating blood meal with toxic larvae, allergic reactions, high fever, respiratory muscle paralysis Inhalation can lead to death
In the production and processing of food, chemical contamination may occur Chemical substances commonly contaminated with food include (12):
• Chemicals used in agriculture such as pesticides, fertilizers, veterinary drugs, weight gainers, growth stimulants, etc
• Food additives (colorants, sweeteners, flavors, stabilizers, antioxidants, detergents )
• Unwanted compounds in food packaging and packaging
• Natural toxins are available in food such as potato sprouts, cassava, bamboo shoots, poisonous mushrooms, puffer fish, toads, bivalve molluscs (shellfish, hard-shell clams), toxin producing molds (mycotoxins) Aflatoxin in moldy corn, peanuts, beans, copra)
Physical hazards in food are foreign bodies from the environment (e.g soil, rocks, sticks, grass, seeds), foreign bodies from broken objects, buildings, manufacturing sites (e.g shards of glass, wood, metal, plastic, hair, bone) or foreign objects accidentally dropped by food handlers (e.g jewelry, hair ties, pens, etc.)
Contaminating food with radioactive substances makes the food harmful to the consumer Radioactive contamination in the food chain (animals and plants) and from the environment can occur when radiation accidentally leaks from research centers, nuclear power plants, or from treatment rooms food preservation by irradiation.( 9)
➢ Sources of physical hazards in food:
Environmental hazards can be incorporated into the product during harvest or post-harvest processing
Postharvest containers, soiled packaging materials and equipment, and transport packaging equipment containing foreign objects
Broken light bulb above food products Damaged equipment and factories Careless or untrained staff
2.4.4.Regulations to control and prevent food safety hazards at restaurants
Health conditions for people who come into direct contact during the processing of prepackaged foods and trading in ready-to-eat foods Participants must not have the following illnesses: whooping cough, diarrhea, hepatitis, respiratory diseases, and potentially infectious wounds Health checks should be carried out before hiring workers and at regular intervals during their employment
General sanitary conditions for food production facilities include: location, environment, layout of workshops, water system, waste recycling, changing rooms for workers, disinfection of tools hand hygiene, clothes…
What are the necessary conditions and enough to ensure food hygiene and safety for all individuals and food business organizations doing business in food
These conditions include equipment, infrastructure, worker health, environment, branding, packaging, etc
Knowledge of food hygiene and safety for individuals directly involved in the production or business of food Includes: Food hygiene and safety (for certification); high food risks, food hygiene and safety conditions, methods of ensuring food hygiene and safety in production, processing, preservation, storage, good hygiene practices and specialized knowledge
Reasons for not ensuring food hygiene and safety
The population explosion along with rapid urbanization leads to changes in people's eating habits The habit of living in a hurry, living in a hurry makes most people not pay much attention to the quality of their meals and the food hygiene and safety status of the food they use (1)
In addition, the population growth also makes natural resources scarce, in which the lack of clean water used for living and eating also has a significant impact on ensuring food hygiene and safety
The rapid development of industries leads to an increasingly polluted environment, affecting livestock and crops Levels of contaminated food increased, especially in ponds and lakes containing industrial wastewater, and high levels of heavy metal residues in livestock (16 )
The increase in the number of factories, large industrial zones, and concentration of workers has a direct impact on food safety, and the urbanization process also has a significant impact on food safety and hygiene
Because environmental protection has not kept pace with socio-economic development, the environment in general and the land and water environment for cultivation, husbandry and aquaculture in particular are still polluted
2.5.2.Direct cause 2.5.2.1.Due to the process of husbandry, cultivation, food production
Food derived from diseased livestock, poultry, or aquatic products living in contaminated water
Vegetables and fruits are fertilized with too much chemical fertilizers, using pesticides that are not allowed or allowed but are not correct in terms of dosage or isolation time Plants grown in contaminated soil or irrigated with fresh manure or contaminated sewage
Using growth stimulants, antibiotics exceeding the allowable limit for livestock
Many food and beverage businesses want to invest little capital but achieve high interest rates, so they look to buy cheap food ingredients that may not be of good quality (for example, buy stale meat and fish) to reprocess into food food sold to customers Business establishments purchase raw materials of unknown origin (without invoices or vouchers)
The process of slaughtering, processing livestock and poultry, and the process of collecting food, vegetables and fruits are not in accordance with regulations
Using additives not in accordance with regulations of the Ministry of Health to process food
Use a cutting board or keep raw food with cooked food
Use a dirty cloth to wipe eating utensils
Contaminated food processing tables, dining tables or eating utensils
Do not wash your hands before handling food
Food handler suffering from infectious disease, diarrhea, abdominal pain, vomiting, fever, cough or skin infection
Many food and beverage businesses do not have enough clean water to process and wash utensils and food, and use unsanitary water to make ice
Cook undercooked or unreheated food before eating Due to improper use and storage
In the process of preserving food, it is not cold enough or not hot enough for bacteria to grow
Leave food overnight or for sale all day at room temperature, food is not tightly covered, allowing dirt, rodents, flies and other animals to come into contact with contamination
Improper transportation and storage of raw food materials should cause additional contamination of raw materials (preservation of marine fish without refrigeration equipment, insufficient amount of ice needed during transportation, causing fish to rot, produce a lot of histamine causing allergies to consumers…).(8)
Using crockery, enameled iron, recycled plastic contaminated with lead to store food Storing and transporting ice in unsanitary, easily contaminated

4.3.1.Environmental hygiene in the kitchen
The kitchen is the place to process food for all workers and production exposure to many harmful microorganisms Types of microorganisms are diverse and abundant, they are present everywhere in soil, water, air If in the process of processing, preserving and distributing food in unsanitary conditions, there are no measures to ensure environmental protection such as waste treatment, killing insects, flies, etc These are favorable conditions for microorganisms, bacteria to exist and grow when they meet favorable conditions, they will penetrate into food and adversely affect to the hygienic quality of food.( 4 )
Table 4.11: Environmental characteristics of the kitchen
Floor By material: tiles The floor of the house is higher than the common ground
Sanitize the processing area Clean, hygienic
Insects, flies in the processing place, where the table is displayed
Few, controlled and prevented by many effective measures
Process rubbish Trash cans have hygienic lids, keep them away from food processing and display areas
Container for leftovers The container has a lid and is hygienic
The reality of the survey results at the company shows that the work of ensuring environmental hygiene is always paid special attention and closely managed by the board of directors and management at the company
The location of the kitchen is separate from the toilet Food receiving area → Food processing area → Food distribution area
The areas in the kitchen are clearly arranged Dining room, dining table, food processing table are kept clean In the kitchen area, equipped with anti-heat system (air conditioner), anti-explosion system (smoke alarm device, fire alarm) and anti-insect net system around the window to prevent insect intrusion The container for leftovers has a tight lid to prevent food from spilling out and water from leaking out Garbage is concentrated far away from the processing place, the dining room Leftover food is delivered daily to households raising animals as animal feed
The floor of the washing and food preparation area is designed with a slope to allow water to escape and not to stagnate and drain The floor of the house is designed higher than the common ground and is paved with foam for convenient cleaning of the dining room environment The walls of the house are painted in bright colors and cleaned to ensure the beauty of the dining room and limit the penetration of insects The toilet area is separate from the kitchen area, convenient for hand washing and personal hygiene to ensure hygiene before entering the restaurant
4.3.2 Food hygiene in industrial kitchens 4.3.2.1.Effects of raw materials and processing tools on the quality of food hygiene and safety in industrial kitchens
To have a good product cannot be from a weak raw material, unsanitary tools Poor quality raw materials can be contaminated with microorganisms right from the stage of care, cultivation or from the storage environment, the containers are not guaranteed, the processing is not guaranteed, all affect the
Raw materials used in food processing in the kitchen include many types, but here we only mention the quality of some main ingredients, we divide them into two main groups:
Group of materials of animal origin and group of materials of plant origin
Group of ingredients of animal origin such as: Meat, fish, eggs, milk, shrimp Is a food that provides the body with many nutrients such as protein, vitamins, minerals According to food safety experts, when buying food, you should choose fresh foods with clear origin Absolutely do not buy cheap foods that have expired or are almost expired, use vegetables with strange and unusual flavors Fresh meat is when the meat is still red and soft, has elasticity, does not have a rancid smell If it is fish, shrimp, squid, the eyes of fish, shrimp and squid must be clear, the meat is not opaque or friable Do not buy and use vegetables with unusual flavors, wilted, yellow, crushed It is recommended to buy vegetables and fruits that are fresh, intact, not scratched, normal in shape, natural in color, firm, and heavy in hand Vegetables and fruits do not wilt, crush or stick to foreign substances, and have no strange taste.(2)
4.3.2.2.Situation of food hygiene in industrial kitchens
The process of importing ingredients for processing in the kitchens is mainly purchased at wholesale markets or imported through familiar suppliers
The worrying thing is that the food does not have a clear origin, is not hygienic, mainly vegetables, meat, and has no commitment to certifying food safety The import of raw materials is difficult to control, partly because the managers' awareness and responsibility have not really paid attention to food hygiene and safety, partly because of the low price of meals
Table 4.12: Types of input materials
Uniform size, clean cut roots Leaves are natural green Characteristic aroma, no strange smell Leaves are fresh, all roots are removed, no mud, no impurities, no crushed
• Japanese red chili (red horn chili)
• Spicy yellow chili (needle chili)
The fresh fruit is firm, whole, uniform, not deep, not deformed, not crushed, not wilted, not rotten Natural color Natural pungent smell, no strange smell
No strange smell Whole fruit, fresh and hard fruit, smooth and shiny skin, Ripe fruit, round evenly, no mud, no impurities, not crushed, not deformed, not deep, not rotten
4.3.2.3.The basic process of importing raw materials of the company
Step 1: Place the ingredients: raw meat, vegetables and fruits, the ingredients themselves are also potentially dangerous due to the process of growing or transporting
Step 2: Transporting materials: Buy at the market or the seller delivers the goods to the company This is a source of microorganisms that can easily infect food by mixing or infecting from the market
• Expired or has a strange color, smell, or rancidity
• Food that is defrosted or re-frozen (with ice crystals on the product)
• Food with torn, open or broken packaging
• Canned goods have the following phenomenon
• Inflate the lid of the box
• Odor, color, abnormal state There is foam or milky liquid
• Stains or water seeping into dry food
• There are signs of damage or contamination on the product
• Mold, signs of insects or rodents
• There are no prescribed labels
Step 4 : Divide and preserve goods
➢ When receiving the goods, it is necessary to follow the order of inspection:
➢ When storing, it is necessary to adhere to the principle of FIFO (first in - first out) and FEFO (first expiration - first out) Always keep the new product below or behind the old one so that the old one is always accessible and used first
• Imported food needs to be rotated to avoid near expiration or expiration
• For non-FIFO imports, the HSD should be read and the expired material should be stored on the outside or on top of the later expired material
• If detecting expired goods, it is necessary to notify the Management Board to cancel the goods
➢ Food labels All goods entering the restaurant must have full labels Return the goods if there is no prescribed label
Expiry date of the day
Figure 4.2: Label details 4.3.2.4.Store goods
• Sealed packaging, product labeling when storing
• Transfer canned food to an appropriate container (glass or plastic container)
• Raw, unprocessed foods are placed in the lower compartment Ready-to- eat or cooked foods are stored in the upper compartment
• Always store food in an airtight container or package
• Do not place food directly on the floor and close to the wall

• For homemade products that need to be washed, put in specialized packaging, the volume of goods to be preserved must not exceed 2kg
• Do not put hot food in the refrigerator
• Dairy products can absorb odors from other foods so it is important to store dairy products in airtight containers and away from products with strong odors
• The cold storage unit temperature must be maintained at 0-5°C at all times
• This temperature keeps microorganisms from growing and doesn't freeze food
• Always control the temperature of the equipment and notify the Management if any cold storage equipment exceeds 5°C
• Leave frequently used foods outside for easy access
• Monitor temperature daily and fill out “Cabinet Temperature Check Form”

4.3.2.7 Preliminary processing, processing and serving products
* NOTE: When preliminarily preparing and processing food, it is necessary to comply with the following requirements:
• Clean the processing table and the CCDC, the equipment used
• Wash your hands properly before touching food
• Keep processing areas, CCDC, equipment clean throughout food processing
• Wash your hands and wipe the table frequently during processing
• Wash cutting boards, CCDC before switching ingredients
• Leave the product at room temperature for as short as possible, no longer than 30 minutes
• Ready-to-eat foods must be processed away from raw foods to avoid cross-contamination
• Change tablecloths regularly and wash them after each use
• Wash the ingredients (including vegetables, meat, seafood, fish) according to the procedure issued by the QA department
• Do not reuse single-use items such as: nylon gloves, wipes, etc
• DO NOT PRELIMINARY COOKING : Pork, Poultry and Mushroom products
Cool down food For small product volume: cool by cover and vent to prevent spoilage If not vented properly, steam will continue to heat the product and increase the cooling time of the product This results in the product being in the temperature danger zone (6 – 60°C) for too long and increases the chance of spoilage product damage Ventilate by punching small holes in the position close to the edge of the CCDC container
With a large volume of products: Put the product into the stainless steel CCDC and put it in an ice bath Continuously stir the product to reduce cooling time Cool the product to 35°C, then divide into containers, label and store
4.3.3 Survey the process of washing food before preliminarily processing and processing
• Clean the basket clean inside and out
Process of washing instant vegetables
Rinse directly under running water or in a tub of clean water Mix chemical solution N1 Dilute the N1 solution according to the instructions on the label Soak in N1
Soak vegetables with N1 solution for 30 seconds For the cabbage, soak for about 2 minutes
Wash with water Change the water when cloudy (usually about 3 washes) to remove impurities in the meat Rinse under running water until clean
Rinse small handfuls under medium-speed running water Rinse in the water bath 2 more times
• Fresh Seafood: Wash twice with water
• Frozen Seafood: Wash it in cold water twice (ratio of ice = 1:1) to keep the quality of seafood good and preserve it longer
Rinse fish under running water to remove dirt and compounds Wash the gills thoroughly
Cut off the container and the base of the mushroom
Rinse mushrooms quickly under running water With dry mushrooms: wash the mushrooms and mushrooms with clean water before doing the next job
• The lampreys are naturally defrosted (leaving the product in the air) then washed, and the outer membrane is removed Cut the length should be 17–23cm
• The lamprey marinade before marinating for the CCDC cover is covered and put in the microwave to melt the fat (1-2 minutes) Lamprey marinated with marinade
Defrost shrimp directly under the tap, cut beard
• Defrost through the refrigerator (maintain at < 5°C, do not open the product packaging)
• Thaw through the fridge/under cold running water (maintain water temperature around 21°C or less The product can be immersed in cold water and changed after 20-30 minutes or under running water)
• Thaw through the refrigerator (maintain at < 5°C, do not open the product packaging) Remove fish scales, bones Divide the rate
Mushroom Cut off the packaging and the base of the mushroom
Instant vegetables Store in an airtight container or cover basket at 1 to 5°C
During use, store at room temperature/cool and cover the top of the basket
Mushroom Seafood Store in an airtight container or cover at 0 to -5°C
During use, store at room temperature/cool and cover the top of the drive tightly
During the preliminary processing of food that is cross-contaminated, food contaminated with toxins will cause poisoning and affect workers' health The equipment system at the company has not been fully invested, most of the equipment has been used for many years, the volume of food storage and preservation is limited, so the processing and preservation of food still encounter many problems difficult In the process of preliminary processing of raw materials, with foods that are vegetables, tubers and fruits because of the large number and human consciousness, the processor has not really paid attention to sometimes they follow the quantity without regard to the quality of the work
With raw materials being instant vegetables, the picking of the old part is not controlled, it is only picked up, or sometimes the head is cut off with a knife and then washed and processed Fruit is washed and then cut, not peeled or soaked in safe brine The process of washing raw materials has not met the hygiene needs, the staff only washes from 2-3 water with a large number of vegetables and tubers, which cannot be guaranteed to be clean and safe
Sanitize water sources
4.4.1 Effects of water sources on the quality of food hygiene and safety in industrial kitchens
Water is a raw material used in many food processing stages as well as in daily life, it can be contaminated by harmful factors such as microorganisms, chemical or physical Contaminated water affects the health of workers in particular and the community in general The company when using the clean water source of the clean water plant needs to sign a contract and have the inspection on hygiene and safety Regularly check the water source, if there are unusual symptoms, immediately notify the investigating health agency, [8]
Drinking water must be boiled or filtered using equipment, water containers must have designed lids, convenient and hygienic faucets, and must be carefully rinsed at the end of the day Annual medical check and water quality test
Figure 4.3: Ensuring food hygiene and safety from water 4.4.2 Sanitize industrial kitchen water
Water used in food processing is indispensable Water used for washing ingredients, food processing, washing tools, etc In food processing, washing ingredients and washing tools is considered a step to remove a large part of microorganisms to ensure hygiene before and after when processing, making the processing process convenient and ensuring food safety and hygiene
The water source at the company's kitchen is clean domestic water provided by the city's clean water company, with a full system of water pipes, ensuring the floor, drains Because used water still contains microorganisms, if reused to wash tools can be a source of infection to the instruments
The company needs to coordinate with the health sector to check the water quality regularly to confirm that the water is clean and hygienic Fully equipped with water filtration and treatment equipment to ensure clean water before use
4.4.3.Personal hygiene in industrial kitchens
Food processing practices, hygienic cooking habits, and proper food preservation depend on the person directly processing them, these are considered the main factors affecting food products Food can be contaminated with microorganisms from people who prepare it through clothing or from carriers of disease Therefore, food handlers need to have certain knowledge of food hygiene and safety practices
The fact is that the processor has a habit of wearing a uniform when going to work, with short fingernails, neat hair, and no infectious diseases Frequently wash hands under running water with soap before distributing meals to workers
Divide food according to tools, do not pick up food when distributing to workers
But it is still limited because the processor still wears jewelry, does not wear an apron and does not wear a mask
The company needs to issue specific regulations on personal hygiene, especially food hygiene and safety in processing Coordinate with interdisciplinary organizations to organize training courses on food hygiene and safety for all employees, especially kitchen staff, to discuss food hygiene and safety in order to raise employees' awareness of food safety and hygiene, and to well implement regulations on food safety and hygiene Food hygiene and safety do not let employees when preparing food or sharing meals without wearing aprons or masks
Evaluate employee knowledge, attitudes and practices
4.5.1 Overall evaluation of Golden Gate company's kitchen staff
The process of recruiting processing staff with high requirements and criteria requires education and skills, the majority of recruitment ages are from 20 to 40 years old with a large number of male candidates suitable for the kitchen profession, salary 3-5 million corresponds to the level of work, so the education level of employees is mainly university graduates, with expertise in processing as well as having in-depth knowledge of food hygiene and safety
4.5.1.1.Gender distribution in serving and processing
Table 4.16: Gender distribution of food service providers
Chart: Gender distribution of food service providers
➢ The percentage of men serving and preparing food accounts for the highest 71%, while men account for 29%
4.5.1.2.Assessment of age group for processing
Table 4.17: Age group distribution of waiters and processors
Chart: Age group distribution of waiters and processors
Table 4.18 Education level of waiters and processors

High school University Freelance labor
Chart: Education level of waiters and processors
The education level of service and processing staff with college and university degrees accounts for the most 73.33% and freelance workers 26.67%
4.5.1.4.Evaluation according to each serving and processing position
In general, from the initial analysis of human resources in the kitchen, it was found that the staff are mostly women, from 20-30 years old, but mainly at the college - university level, with high ability in processing knowledge and skills Food safety should be good attitude, good responsibility to food hygiene in
4.5.2.Knowledge of staff about food hygiene and safety
Every year, the company creates conditions for managers and kitchen staff to participate in training, knowledge training and learn about food safety to improve knowledge and understanding, after each survey training course, screening and evaluation However, due to the different educational levels of employees, the results of training and knowledge are also different, specifically evaluated as follows

4.5.3.Evaluation of food hygiene and safety practices
The evaluation results show that, from knowledge to practice, processing staff still encounter many errors in terms of processing hygiene and use of labor protection, which is caused by the lack of staff knowledge and personal awareness Their employees are not high, this is also one of the basic causes leading to unsafety in industrial kitchens

From the above evaluation results, it is shown that the qualifications of the processing and serving staff at the collective kitchen have not completely met the requirements of food hygiene and safety Although they have been trained on preserve fresh food perfect due to the awareness and training process of each individual From the two main analyzes above, it shows that the education level and awareness of workers are not high, so the lack of practical ability is also one of the causes affecting the quality of food and the health of workers
4.5.4.Assessment and detection of food safety and hygiene hazards of the kitchen kitchen at the company
4.5.4.1.Assessment of potential hazards during processing
Safe food is food that is not harmful to human health In order to ensure food safety, quality and health for workers, processing staff must have the responsibility and obligation to improve and ensure food quality Managers and individuals need to identify harmful hazards in food, in order to control and prevent comprehensively in the processing and production stages
Table 4.29: Detection of potential hazards during food processing
Stage Type of hazard Potential danger
Microorganisms on the surface of raw materials, molds Aspergillus ochraceus, E.coli, Samonella , have the ability to produce toxins, insects, and weevils
Chemical hazards Residues of pesticides, heavy metal content, natural toxins, allergens
Physical danger Metal, garbage, impurities, …
Biohazards Microorganisms causing infectious diseases
Chemical hazards Residues of pesticides and antibiotics
Physical danger Insect corpses, impurities, hair, nails…
Processing Biohazards Microorganisms causing infectious diseases
Stage Type of hazard Potential danger process
Chemical hazards Food is degraded, unwanted reactions occur, using food additives in excess Physical danger Burnt food Metals, impurities, grit, hair, etc
Biohazards Microbial contamination from storage equipment or the surrounding environment
Chemical hazards Food is changed due to inappropriate storage conditions, easy to produce toxins, rancid
Physical danger Impurities, dust, hair, nylon…
4.5.4.2.Sources of hazards in food hygiene and safety at restaurants
To control and prevent hazards, processing personnel need knowledge and understanding of the sources of hazards Biological hazards from the surrounding environment and originating from the habits and consciousness of each person
Physical hazards are common and easily acquired during processing, but are not difficult to eliminate; chemical hazards are difficult to detect from raw materials and partly due to the irresponsibility of the processor
Unhygienic environment (Residual chemicals in fruits and vegetables due to the use of chemicals)
Lack of hygiene during processing, personal hygiene is not guaranteed (Jewelry from people, hair, nails, cough, etc.)
Unhygienic food storage (Leave food at humid temperature, insect penetration)

There should be proper investment attention in terms of ground conditions, tools and equipment for the dining room and kitchen Set standards when recruiting kitchen staff in terms of education level, working seniority and ensuring adequate health conditions and training on food hygiene and safety knowledge
Figure 4.5: Proposing measures to reduce food safety hazards from managers 4.5.2.Raw material import process
When manufacturing any product, the first important factor needed is the source of input materials
When purchasing raw materials for food production and processing, it is advisable to have a contract with the supplier of the raw material, with a commitment to the quality of the supplier's raw materials When receiving raw can use testing equipment: rapid and sensory test to detect raw materials unsatisfactory food
It is necessary to record and record information on the origin, composition of food and raw materials purchased
Frozen foods, dry foods and seasonings should be imported in sufficient quantities for a day and required to be delivered on the day of food preparation, thus ensuring perishable foods such as meat, fish and bivalve molluscs, vegetables… are eligible for good preservation
Storage process has a great influence on food quality Each product has requirements on storage conditions during circulation and distribution
Food preservation is to keep the original (natural) quality of food from being damaged, contaminated, or deformed during the storage period
Figure 4.6: Preserve food to avoid contamination, ensure food safety and hygiene
➢ Some basic principles and conditions are as follows:
• Aseptic measures to prevent food contamination
• Measures to maintain the biological static state of microorganisms to prevent the growth of bacteria in food by means of controlling temperature, humidity, water activity, osmotic pressure and preservatives difference…
• Measures to destroy, kill microorganisms, kill all bacteria, molds, yeasts and spores at different temperatures such as cooking, pasteurization, canning, irradiation
• Refrigerate food: keeping the temperature no more than 5°C can slow down the growth of pathogenic bacteria in food However, there are many types of microorganisms with high nutritional requirements that often cause food degradation, and some pathogenic bacteria can still grow even at 0°C
Ensure the production process needs attention: clean ingredients should not be mixed with dirty ingredients, and different ingredients (meat, vegetables, fish) should not be mixed together Cooked food should not be mixed with raw food
Followed by the tools, equipment, and people must also be separate
Preparation for food processing is essential to ensure that during processing (heating) the minimum temperature inside the piece of food is just enough to kill microorganisms to an acceptable level, but not hot enough to kill spores and toxins It should be between 63°C – 74°C and kept at this temperature for at least 15 seconds
The instant vegetables and fruits: must be washed under running water (water suitable for drinking) and, if necessary, cleaned with a chemical solution
Only use additives, processing aids in the list of permitted use; use the
Water used in food production and processing must be clean water according to regulations (QCVN 01:2009/BYT) The cleaning, cleaning and disinfecting agents for processing tools must be chemicals that are not harmful to human health and the environment.( 9 )
CONCLUSION AND RECOMMENDATION
Conclusion
➢ The kitchen scale has been surveyed with some characteristics : The location and surroundings at the restaurant ensure food hygiene and safety standards
The kitchen structure is suitable, meeting food hygiene and safety standards
Equipment in the kitchen ensures compliance with regulations and meets food hygiene and safety standards
➢ Surveyed the implementation of food hygiene and safety procedures in the kitchen:
Evaluate the results of staff participating in training, knowledge training and learning about food safety with high achievements
Evaluate employees who practice food hygiene and safety procedures that meet VSATPP standards with high achievements
Assessing the quality of water in the kitchen to meet food hygiene and safety standards
➢ Very few food safety hazards have been detected in the cooking process in the kitchen:
Lots of expired ingredients left over
➢ Evaluation of participation in training, knowledge training and learning about food hygiene and safety:
Through training and testing exercises for all employees on food hygiene and safety, a large number of employees achieved good results with 99/100
Including: knowledge on food hygiene and safety; knowledge about food poisoning; knowledge of personal hygiene; knowledge of processing hygiene; knowledge of equipment hygiene and food preservation.
Recommendation
Due to the limitation of time and experimental conditions, the survey only stops at the level of observation, data collection and evaluation I propose to continue to investigate and analyze specific microbiological criteria, assess hazards in the kitchen and propose handling and remedial measures
