3Food borne illness - how it occurs Food borne illness - how it occurs? GM’s WK#1 lesson A food borne illness is a disease that is transferred to people by food.There are three types of hazards---biological, physical, and chemical.Moist, high in protein and slightly acidic.Examples are dairy products, eggs, meat and poultry, seafood, raw vegetables, (alfalfa sprouts, cut melons, baked potatoes, beans, rice, and garlic and oil mixtures), and soy products, like tofu.Biological hazards are bacteria, viruses, parasites and fungi. The key factor in controlling bacterial growth is to control conditions that favor that growth.These are the factors:FoodAcidityTimeTemperatureOxygenMoistureMonitoring time and temperature can most easily control bacterial growth in food.
4Week 1 take back…How foods become unsafe: Remind employees that there are three major factors that can cause food to become unsafe.TIME AND TEMPERATURE ABUSE: The Temperature Danger Zone is 41° to 135°. Move food out of this temperature range by cooking it to the proper temperature, freezing it, or by refrigerating it at 41° or lower. The four-hour rule limits the time food spends in the temperature danger zone. Prepare food in small batches and as close to the time of service as possible.Improper procedures are:Failure to properly cool foods.Cooking incorrectly.Not correctly handling food cooked previously.Allowing food to stay at room temperature for too long.
5Food borne illness – cross contamination Food borne illness – cross contamination? GM’s WK#2 (1 of 2 part lessons) A food borne illness is a disease that is transferred to people by food. Contributing Factors:CROSS-CONTAMINATION: How food and food-contact surfaces become contaminated. Raw food comes in hand to hand contact with ready to eat foods.Raw food drips onto ready to eat foods. Food contact surfaces such as cutting boards, knives and splash areas come into contact with raw foods. Raw food is added to food that receives no further cooking.POOR PERSONAL HYGIENE:Humans are the biggest source of foodborne illness because of improper hand washing practice.
6Week 2 take back… part 1How to keep food safe during the flow of food:Here are examples of how food can become unsafe at each step of the flow of food because of time and temperature abuse, cross-contamination, and poor personal hygiene. The steps include:Receiving - Correct temperatureHolding - Correct time and temperatureStoring - Away from chemicalsServing - Contamination and personal hygienePreparing - Proper temperature and timeCooling - Correct temperaturesCooking - Know cooking temperatures for various foodsRe-heating – Know how to return food to serving condition
7Week 2 take back…part 2 The basics of food safety: Keep things clean and sanitizedPractice good personal hygieneWash hands thoroughly and frequentlyMinimize the time food spends in the temperature danger zone.Prevent cross-contaminationHow to prevent cross contamination:Create a physical barrier Assign specific equipment to each type of food—separate cutting boards should be used for raw and cooked foodsClean and sanitize tools, equipment and utensils after each task. Create procedural barriers. Prepare raw and ready to eat foods are different times Purchase ingredients that require minimal preparationTime and temperature control: To prevent time and temperature abuse: Cook, hold, cool, and Re-heat food properly.
8ENSURING PROPER PERSONAL HYGIENE ENSURING PROPER PERSONAL HYGIENE? GM’s WK#3 A food borne illness is a disease that is transferred to people by food.How employees can contaminate food:When they fail to wash hands after using the restroom,After touching their hair, face, or body and then touching food.By coughing or sneezing near food or food surfaces.By touching or scratching a cut or abrasion and then touching food.After touching anything that can contaminate food.Personal cleanliness practices: Report illnessShower or bathe dailyBandage any cuts and abrasions; always wear gloves over bandagesClean and trim fingernailsAvoid wearing nail polish or false fingernailsLeave all jewelry at homeWear clean uniforms and apronsAvoid eating, smoking, or drinking on the jobWear a hair restraint when working with food
