3 10 Safety Myths Don’t be “myth”-led! Following are the facts for 10 common food safety myths...
15 Less common, but possible severe conditions Paralysis Death Meningitis
16 Myth 4 If I’ve never been sick from the food I prepare, I don’t need to worry about feeding it to others.
17 Fact 4 Some people have a greater risk for foodborne illnesses. Is the food safe for everyone at the table? A food you can safely eat might make others sick.
18 People with a higher risk for foodborne illness Pregnant women Infants Young children and older adults People with weakened immune systems and individuals with certain chronic diseases
19 Myth 5 People never used to get sick from their food.
20 Fact 5 Many incidents of foodborne illness went undetected in the past.
21 Symptoms of nausea, vomiting, and diarrhea were often, and still are, blamed on the “flu.”
22 Foodborne illness vs. flu More common in foodborne illness: Gastrointestinal Nausea Vomiting Diarrhea More common in flu: Respiratory Chest discomfort Cough Nasal congestion Sore throat Runny or stuffy nose
23 More reasons for foodborne illnesses than in the past... Bacteria have become more potent over the years.
24 Still more reasons... Our food now travels farther with more chances for contamination. In days gone by, the chicken served at supper may have been in the hen house at noon!
25 Myth 6 As long as I left the lid on a food that has sat out too long, it is safe to eat.
26 Fact 6 Though food may be safe after cooking, it may not be safe later. Just one bacteria in the food can double in 20 minutes!
27 How many bacteria will grow from one bacteria left at room temperature for 7 hours?
29 Refrigerate perishable foods within two hours at a refrigerator temperature of 40°F or lower.
30 On a hot day (90°F or higher), food should not sit out for more than one hour.
31 Myth 7 If you let a food set out for more than two hours, you can make it safe by heating it really hot!
32 Fact 7 Some bacteria, such as Staphylococcus (staph), produce toxins that are not destroyed by high cooking temperatures. Image: Content provider: CDC/Matthew J. Arduino, DRPH, Photo credit: Janice Haney Carr
33 Did you know “Staphylococcus” comes from a Greek word meaning “a bunch of grapes?”
34 Myth 8 If a hamburger is brown in the middle, it is cooked to a safe internal temperature.
35 Fact 8 1 out of 4 hamburgers turns brown before it has been cooked to a safe internal temperature. http://origin-www.fsis.usda.gov/PDF/Thermometers_Are_Key_FactSheet.pdf
36 Which ground beef patty is cooked to a safe internal temperature? http://origin-www.fsis.usda.gov/PDF/Thermometers_Are_Key_FactSheet.pdf
37 This IS a safely cooked hamburger (internal temperature of 160ºF) even though pink inside. This is NOT a safely cooked hamburger. Though brown inside, it is undercooked. http://origin-www.fsis.usda.gov/PDF/Thermometers_Are_Key_FactSheet.pdf
38 Research shows some ground beef patties look done at internal temperatures as low as 135ºF. A temperature of 160ºF is needed to destroy E. coli. http://origin-www.fsis.usda.gov/PDF/Thermometers_Are_Key_FactSheet.pdf
40 How to use a food thermometer 1.Wash thermometer with hot soapy water before and after use. 2.Use before the food is expected to be “done.” 3.Place in the thickest part of the food, not touching bone, fat or gristle. 4.Compare reading to USDA recommended safe minimum internal temperatures.
41 USDA has revised its recommended cooking temperature for all whole cuts (steaks, roasts, and chops) of meat, including pork, beef, lamb and veal to 145 °F and then allowing a 3 minute rest time before carving or consuming. 41 Photo courtesy of FSIS/USDA Image Library
42 A “rest time” is the amount of time the product remains at the final temperature, after it has been removed from a grill, oven, or other heat source. 42 Photo courtesy of Cattlemen’s Beef Board & National Cattlemen’s Beef Association
43 During the 3 minutes after meat is removed from the heat source, its temperature remains constant or continues to rise. This destroys pathogens and produces a product at its best quality. 43
44 3 temperatures to remember Ground meats (including ground beef, veal, lamb, & pork): 160 °F with no rest time All poultry (including ground chicken & turkey): 165 °F with no rest time Whole cuts of meat (including pork, beef, lamb, & veal steaks, roasts, & chops): 145 °F with addition of a 3 minute rest time
45 Photo courtesy of Cattlemen’s Beef Board & National Cattlemen’s Beef Association This change does NOT apply to ground meats, including ground beef, veal, lamb, and pork, which should be cooked to 160 °F and do not require a rest time.
46 Photo courtesy of FSIS/USDA Image Library The safe cooking temperature for all poultry products, including ground chicken and turkey, remains at 165 °F.
47 Food thermometers & thin foods On an “instant-read” dial thermometer, the probe must be inserted in the side of the food so the entire sensing area (usually 2-3 inches) is positioned through the center of the food.
48 Food thermometers & thin foods When possible, use a digital thermometer to measure the temperature of a thin food. The sensing area is only ½- to 1-inch long and easier to place in the center of the food.

50 Myth 9 Meat and poultry should be washed before cooking.
51 Fact 9 Washing meat and poultry is NOT necessary or recommended.
52 Washing increases the danger of cross- contamination, spreading bacteria present on the surface of meat and poultry to: ready-to-eat foods kitchen utensils counter surfaces.
53 Cooking meat and poultry to the recommended internal temperature will make them safe to eat.
54 Myth 10 We should be scared of eating almost everything!
55 Fact 10 “... the American food supply continues to be among the safest in the world.” Robert E. Brackett, Ph.D., Director, Center for Food Safety and Applied Nutrition, Food and Drug Administration, U.S. Department of Health and Human Services, November 15, 2006 http://www.hhs.gov/asl/testify/t061115a.htmlhttp://www.hhs.gov/asl/testify/t061115a.html
