Nutrition and Food Preparation 1 Food Safety Notes
Why is Food Safety Important? An estimated 48 million Americans suffer from food-borne illness (food poisoning defined as an illness caused by consuming contaminated food or beverages.) every year. Food-borne illness may be mild(flu like symptoms: diarrhea, nausea, vomiting, stomach cramps) (1-2 days) or severe (hospitalization or death). Children, pregnant women, elderly & people with chronic illness are most at risk
What causes Food-Borne Illness? Most food-borne illness can be traced to harmful microorganisms – tiny living creatures visible only through a microscope. Types/examples: Listeria, salmonella, e coli, campylobacter, botulism, etc. Poor food handling practices allow harmful micro-organisms to grow and spread.
Common Reasons for Food Borne Illness Pair/share: Find one example we have control over? 40% improper cooking of foods 21% holding time for food (time between prep and serving of food) 20% infected persons touching food 16% inadequate cooking of foods 16% improper food storage 12% inadequate heating of food 11% contaminated 7% cross contamination 7% improper cleaner used 4% use of leftovers
Take Action Against Food-Borne Illness So…how can we prevent & reduce the chances of bacteria growth while cooking in this class? http://www.youtube.com/watch?v=YH8gm7xm-7Y&playnext=1&list=PL792859FC2DDD61B2&feature=results_video
Clean-Cook-Chill-Contain Cross- Contamination So…how can we prevent & reduce the chances of bacteria growth while cooking in this class? Clean-Cook-Chill-Contain Cross- Contamination Wash hands in between touching different foods Thoroughly cook all meat Keep food chilled Avoid cross contamination
6 Conditions for Bacteria Growth F 1. Food- especially food high in protein A 2. Acidity level – especially from 4.6 to 14 T 3. Temperature – 41 degrees to 135 degrees (DANGER ZONE) T 4. Time – more time allows enough bacteria growth to cause illness O 5. Oxygen – thrives with oxygen M 6. Moisture – thrives in moist environments
Time
Potentially Hazardous Foods (defined as a food item that would support rapid bacterial growth) Any food of Animal origin Meat: beef, chicken, fish, eggs Dairy products: milk, cheese, yogurt Plant origin Cooked starches like oatmeal, rice, potatoes Cooked vegetables Tofu Sprouts Cut Melons, cut tomatoes, and cut leafy green vegetables Garlic or herbs bottled in oil
Personal Cleanliness 1. Avoid handling food when you are ill (diarrhea, vomiting, etc.) or if you have cuts or sores on your hands. (use gloves if needed) Wash hands before food preparation, after sneezing, coughing, using rest room , touching face or hair, and handling raw meat/eggs. Keep hair away from face. Bring hat or hair ties for hair. Wear clean clothes/apron (dirty clothing carries bacteria) Avoid tasting food while cooking – licking of fingers is prohibited. One taste with a clean spoon only!
Kitchen Cleanliness Use hot, soapy water on dishes Don’t wipe hands on dish towel – use paper towels so dishes don’t get bacteria Sanitize & wash cutting board that has had meat before cutting anything else or use separate cutting boards(cross contamination ) Keep your kitchen pest free. A house fly landing on your food can spread salmonella and staph bacteria
Equipment Guidelines Use clean equipment and supplies Use equipment for it’s intended use Do not touch food with hands if tongs, a fork, or a serving spoon can be used. Wipe electrical appliances…do not immerse in water!
Vocabulary Pair/Share: What is the difference between Cleaning and Sanitizing? Cleaning: removing visible dirt, soil, dust, or food waste. Sanitizing: reducing the number of microorganisms, bacteria on a surface to safe levels with an ammonia or bleach solution Cross-Contamination: letting micro-organisms spread from one food/surface into another
Avoid Cross-Contamination https://www.youtube.com/watch?v=Xm_X5LJmrbw Keep work areas clean Keep raw and cooked products separate during food preparation. After using cutting boards and tools for cutting raw meat or eggs, wash thoroughly and disinfect. Keep separate cutting boards for raw foods and cooked foods Never place cooked meat on a plate that held raw meat. Store fresh meat products on trays on the lowest shelf in the refrigerator.
Food Preparation & Storage Danger Zone: 41-135 degrees Keep cold foods at 40 degrees F or below. Keep hot foods at 136 degrees or higher. Move food through the danger zone within a 2 hour time period! Thaw frozen foods in the refrigerator (not on the counter) If you thaw foods in the microwave cook immediately. Maintain the refrigerator temperature at 38 to 40 degrees F. Cool foods before refrigerating or you will increase the temperature of your refrigerator! https://www.youtube.com/watch?v=T5C335jleZA
Properly Arrange/Store Food in Fridge Store raw meat below ready to eat foods. This order is suggested to prevent raw food juices from dripping on ready-to-eat food. The order of food placement is based on the minimal internal cooking temperature of each food. Ready-to-eat food Whole fish and seafood Whole pieces of beef and pork Ground beef Poultry
Food Preparation Tips…. Wash tops of cans before opening them to keep dust and bacteria out of foods. Do not use dented, leaking or swollen canned goods. Wash fresh fruits and vegetables thoroughly to flush away pesticides and dirt before preparation.
Destruction of Organisms Cooking food is not only to enhance flavor but it also helps to kill bacteria Proper cooking temperatures: in order to tell if meat is properly and thoroughly cooked 165 degrees and above- chicken, pork, stuffing, casseroles, leftovers 155 degrees and above – ground meat: beef and sausages 145 degrees and above – lamb, fish, beef, eggs 135 degrees and above - ready to eat foods (hot dogs) and vegetables
