Health and Safety Child Care Centers and Family Day Care Homes Program Issues Environmental Health Food Safety Environmental Safety Food Safety ACTIVITY — True or False 1. Everything that looks clean is free of microorganisms. 2. Wiping the tabletop or other surface with a damp cloth removes harmful microorganisms. 3. Bacteria grow more quickly between 45oF and 140oF. 4. Cross-contamination is the transfer of harmful bacteria from one food to another. 5. If an infant does not drink all of the milk in their bottle, refrigerate the leftovers for the next feeding. 6. Bleach is an effective sanitizer. 7. Set your refrigerator to 39oF or colder to slow bacterial growth. 8. Most foodborne illnesses are due to viruses. Background What is Foodborne Illness? A foodborne illness is caused by food that has been contaminated by bacteria, viruses or parasites. You can not tell if the food has been contaminated by looking, smelling or tasting the food. Is Foodborne Illness Common? Every year about 76 million Americans get foodborne illness. Most cases are not life-threatening. But . . . more than 5,000 people die and 325,000 are hospitalized due to complications. Who is at Risk? Serious complications are more common in highrisk populations such as: young children, pregnant women, elderly persons, and the chronically ill. What are toxins? They are poisons that can form when food has been temperature-abused. Cooking food will not necessarily destroy toxins and so keep food hot or cold to prevent them from forming. How do I know if I have foodborne illness? The most common symptoms for foodborne illness are: diarrhea nausea vomiting fever These symptoms usually begin 6 to 24 hours after you eat contaminated food. These symptoms are often confused with the flu. Buying and Receiving Where should I get my food? Buy food from an approved source, such as a grocery store or a food retailer. Home canned foods, unpasteurized dairy foods and wild game cannot be served in child care centers. They have not passed a state or federal inspection and so might be unsafe. What do I look for when opening cans and jars? Before opening cans and jars, check for: leaks; bulges, including bulging lids; severe dents; cracks; and loose lids. Never buy or use any food in questionable containers. When in doubt, throw it out! How can I tell if a can or jar of food is safe to eat? Check for: bad smells; spurting liquid; and/or bubbles. These are signs that gas or acid has formed, and that means bacteria has probably grown in the food. Can I have pets in my center? Do not allow pets to walk on countertops or in food preparation areas. Keep caged animals, such as turtles, gerbils or hamsters, out of food preparation areas. Always wash your hands after touching an animal. Animals carry harmful microorganisms on their bodies, such as Salmonella. Are moldy foods safe to eat? No. Throw out food that is moldy because some molds can produce toxins. Moldy fruit, vegetables and breads should be thrown out. Cooking will not destroy the mold toxins. Storage What is a potentially hazardous food? Any food can cause foodborne illness. However, bacteria can only grow in potentially hazardous foods. Potentially hazardous foods are moist, low acid, and have some protein. To prevent bacteria from growing, keep potentially hazardous foods at 140oF or hotter or 45oF or colder. Can improper storage make food unsafe to eat? Food may be safe when you buy it, but improper storage can make it unsafe to eat. Proper storage can slow food spoilage. More importantly, proper storage can prevent cross-contamination and bacterial growth. Storing How To’s Store unopened, non-perishable food: in a cool dry area; on clean shelving that is at least 12 inches off the floor or in clean kitchen cupboards; and in a tightly covered container if removed from its original packaging. Label and date the container, not the lid, with the name of the food. Are there any places that I cannot store food? Never store food under any plumbing lines (especially kitchen sinks). If the lines drip, food can become contaminated. Never store food on the floor. Dirt, rodents, insects or water that might be on the floor can contaminate the food. Can food become unsafe while stored in a refrigerator? Yes. Bacteria can grow in food when the food is in the temperatures danger zone for more than four hours. To prevent bacteria from growing, set your refrigerator temperature no higher than 390F. Use potentially hazardous foods within seven days. Refrigeration How To’s Store perishable foods in the coldest part of the refrigerator — usually toward the back of the refrigerator. Wrap raw meat, poultry and fish with plastic wrap or aluminum foil before refrigerating. Store raw foods that drip on the lowest shelf of the refrigerator so their juices do not contaminate other foods. How do I check refrigeration temperatures? Check refrigerator temperatures by putting a thermometer inside the refrigerator near the door. It should read 39oF or colder. If it does not, adjust the dial as needed. Also check the temperature of the food. The food should be no warmer than 45oF. Can freezing temperatures make food safe to eat? No. Freezer temperatures slow bacterial growth but do not necessarily kill bacteria. Therefore, if a food has been temperature-abused before freezing, it will be unsafe upon thawing. Keep freezer temperatures at 0oF or older. Use a freezer thermometer to check freezer temperatures. How do I handle foods that children bring from home? Check food that children have brought from home. If food needs to be kept cold, refrigerate immediately. If not, store in a clean area that is not on the floor. Always label and date the food brought from home if that is allowed in your home or center. Preparation ACTIVITY — TM Glo-Germ Upon completion of this activity, you will be able to determine if you are properly washing your hands. Why is handwashing so important? Hands carry many harmful bacteria and improper handwashing (or not washing at all) is a common cause for foodborne illness. Handwashing How To’s Wash your hands with antibacterial soap and water for at least 20 seconds. Rinse thoroughly. Dry with a clean paper towel or other approved device. Must I always wash fruits and vegetables? Yes, if you plan on eating the peel. Harmful microorganisms might be on the peel. Washing How To’s Clean tough-skinned fruits and vegetables, such as cucumbers, melons or apples, with a vegetable brush and lukewarm water. Never use soap or detergents; the residue could make you sick. Soak more delicate fruits and vegetables for a few minutes in lukewarm water, then rinse thoroughly. You do not need to wash bananas or oranges. Can bacteria grow when I am thawing frozen foods? Yes. Freezing only kills some bacteria. Therefore, frozen foods will still be contaminated. If a food is improperly thawed, such as on a countertop, the bacteria that is in the food can grow and possibly cause foodborne illness. Thawing How To’s Put frozen food in the refrigerator one or two days before it is needed. or Microwave on the thaw or defrost setting immediately before cooking, or Cook thoroughly. Never refreeze food that has been improperly thawed or held at unsafe temperatures. Special Consideration — Eggs Thoroughly cook until the white and yolk are firm. Never eat partially cooked eggs. Never allow children to lick the spoon or taste egg-based batter or dough. Foods that Might Contain Raw or Undercooked Eggs Cake batter Cookie dough Homemade eggnog Homemade ice cream French toast Quiche Cooking Why do I need to have a food thermometer? Proper food temperatures are critical to the prevention of foodborne illness. The only way to accurately determine if a hot food is hot and a cold food is cold is to measure the temperature of the food with a thermometer. ACTIVITY — Thermometer Upon completion of this activity, you will understand why you need to check the accuracy of your thermometers each day. Thermometer How To’s Use a thermometer that has a temperature range between 0oF and 220oF Clean and sanitize the stem before and after each use. Check the accuracy every day. Do so by placing the stem in boiling water (boiling is 2120F) or ice water slush (freezing is 320F). Adjust if needed. Does cooking make food safe? Yes. Proper cooking makes most foods safe because the process kills harmful microorganisms, such as bacteria, some viruses, and parasites. Cooking is the process of heating food for a long enough time and at high enough temperature to kill harmful microorganisms that might be present. Remember — food must be stored properly before cooking or cooking might not be effective. How hot is hot enough? Whole cuts of beef or pork – 1550F or hotter Ground beef – 1550F or hotter Poultry/eggs – 1650F or hotter Leftovers – 1650F or hotter Fish – 145oF or hotter Why must I continuously cook a food? Bacteria can grow in partially cooked food. Remember — bacteria love it when the temperature of the food is between 450F and 1400F. Are there special considerations for microwave cooking? Yes. Always stir while heating and rotate food to distribute heat. Microwaved food may have cold spots which are ideal for bacterial growth. Reheat leftovers to a minimum of 1650F and serve immediately. Leftovers Can improper cooling make foods unsafe to eat? Yes. Bacteria can grow when food is in the temperature danger zone. If food is improperly cooled, it can be in the temperature danger zone for more than four hours, so bacteria might be able to grow. Cooling How To’s Put cooked food in shallow pans or containers. Loosely cover the pans with a lid, plastic wrap or foil. Label and date. Refrigerate immediately. Use foods within 3-4 days after cooking. If you cannot use the food in this time frame, freeze the food. Reheating How To’s Reheat leftovers to 1650F or hotter. Never reheat food in a crock pot or a slow cooker. This type of equipment takes too long to heat food to safe temperatures. Throw out leftovers that are more than 3-4 days old. Sanitizing ACTIVITY -- White Powders You will be able to better understand why it is so important to properly label chemicals. Why is it so important to sanitize? Cleaning is the removal of dirt, food and grease from a surface with soap or detergent and water. However, sanitizing is killing harmful microorganisms that can be on a surface even if it looks clean. This is done with a sanitizing solution. Sanitizing Solutions Unscented household bleach is an approved sanitizer. It is inexpensive and widely available. Your Environmental Health Specialist can tell you about other sanitizers that are also approved for use. Making Your Own Sanitizer Mix 1 tablespoon of unscented household bleach with 1 gallon of warm (not hot) water. Store mixture in a labeled spray bottle. It can be used for up to one week as long as the bottle is stored in a cool, dark and safe area. What do I need to sanitize? Before and after preparing food, always clean and sanitize: • • • • • • countertops sinks highchair trays tables used for eating placemats bibs How do I sanitize a surface? 1. Clean surface with warm soapy water 2. Rinse with clean water 3. Thoroughly saturate the surface with sanitizing solution Spread the sprayed solution over the surface with a clean paper towel 4. Air dry. Do not rinse off the sanitizing solution Do not use this method to sanitize dishes, glassware, utensils, cutting boards or pot and pans How do I sanitize in a sink? Glassware, cutting boards, dishes, utensils, pots and pans need to be cleaned in a threecompartment sink. This is called immersion sanitizing. 1. Wash dishes in one sink 2. Rinse in the second sink, and 3. Sanitize in the third sink for at least 1 minute. 4. Air dry. A dishwasher can be used if its final rinse temperature is 1650F or hotter. Meal Time Before snacks and meals: Always wash yours and the children’s hands before meal time with soap and water. Use utensils, not your hands to serve food. Clean and sanitize counters and tabletops before serving food. Serve hot food hot and cold food cold. Do not put food on the table before the children are ready to eat. Serving How To’s Do not let children share the same utensil or dish when eating. Provide a clean and sanitized utensil for each serving bowl and dish. Don’t lay utensils on the table as they could become contaminate the food when the utensil is used to get seconds. Serving How To’s (continued) Do not let children serve themselves from large boxes of cookies, cereal or crackers. Children’s saliva can contain harmful bacteria that can be transferred to other children. If children serve themselves, harmful microorganisms on their hands can contaminate the food in the box. Serving How To’s (continued) Do not allow children to eat food that has fallen to the floor. The same goes for utensils. Use a new one or clean and sanitize the “fallen” one. Many centers just use disposable utensils and plates. After Snack and Mealtime: Throw out uneaten food that has been served but not eaten. (Don’t put them back in the jar or bag.) Never put milk or other beverages that have been poured into glasses or cups back in their original containers. The same goes for any other food utensil that has been put within reach or sneezing distance of the children. What can I save? Unpeeled fruits – wash before putting them in storage. Unopened nonperishable packaged food ACTIVITY — Toss or Save Which of the following foods must be thrown out after a meal? Juice in a cup Unopened cartons of milk Unpeeled bananas Half eaten peanut butter sandwich Spaghetti that is sitting on a stovetop burner Field Trips Food Safety for Field Trips Safe foods for outings are: Peanut butter sandwiches Jelly sandwiches Cookies Crackers Fresh unpeeled fruit Commercially dried fruit Unopened cans of fruit or pudding Which foods must I keep cold? Meat sandwiches Milk or foods that contain milk Peeled or cut fruits and vegetables Opened cans of fruit Keep them cold by using insulated lunch bags with a frozen gel pack or with a frozen juice box, a leakproof container of water that has been frozen. Also freeze sandwiches. Infants and Toddlers Baby Food After opening, label the can or jar with the name and date and time opened. Refrigerate un-served portions in the original jar. Throw away unused portions within 36 hours after opening, but one day (24 hours) is preferred. Observe the “use by’ date on the unopened jars of baby food. Never feed the baby directly out of the jar. The bacteria in the saliva will make the food contaminated and make the unsafe Breast Milk Ask parents to label each container with the name of the child and date pumped. Refrigerate and use breast milk within one day. Remind parents to refrigerate breast milk in a sterilized bottle. Formula-fed Babies Refrigerate and use prepared formula within one day Throw out leftover formula in the bottle after the feeding or after one hour. Never add new formula to half-filled bottle of formula. Bacteria and viruses in baby’s saliva could be in the old formula and contaminate the new formula. Prepared by: Angela M.
