Cook to proper temperatures, checking with a food thermometer.
Even for experienced cooks improper cooking and reheating of food means bacteria can survivie. Use a food thermometer-you can't tell food is cooked safely by how it looks, tastes, feels, or smells.

Temperature Matters
-
Refrigerator temperatures should be 40°F or slightly below
-
Freezer temperatures should be 0°F or below
-
Remember the 2 hour rule! NEVER keep perishable food out of refrigeration for longer than two hours, and one hour if the temperature is above 90°F
-
Avoid keeping perishable food between 41°F-140°F, bacteria grow best in this range, also known as the DANGER ZONE
-
Cook eggs until the yolk and white are firm, not runny.
-
Don't use recipes in which eggs remain raw or only partially cooked.
Why is the rest time important?
After you remove meat from a grill, oven, or other heat source, allow it to rest for the specified amount of time. During the rest time, its temperature remains constant or continues to rise, which destroys harmful bacteria.

Food Thermometers
-
Thermometers for your refrigerator, freezer, and food can cost less than $10.
-
Find these thermometers at your local food market, hardware store, kitchen store, and online.
-
Appliance thermometers are critical during a power outage.

Did you know consumers ALWAYS use a food thermometer for:
-
Large pices of red meat is 37%
-
Poultry (thigs, wings, breats, etc) is 17%
-
Hamburgers is 9%
-
Egg dishes (quiche, bread pudding, etc) is 3%

Reheating foods safely
-
The microwave, stove top or the oven is the quickest way to safely reheat foods as quickly as possible
-
Foods must be reheated within the two hour rule so as not to linger in the DANGER ZONE of 41°F-140°F
-
When using the oven to reheat, set the oven no lower than 325°F
-
Slow cookers are safe to cook with, but NEVER use a slow cooker to reheat leftovers. The slow cooking temperature would keep the food in the danger zone (41°F-140°F) for too long
Microwave Cooking
Microwave cooking does not always provide even heating. So here are some tips:
-
Stir and rotate food part way through the cooking or heating to avoid "cold spots"
-
Use a food thermometer to ensure the proper internal cooking temperature of the food item.
-
Break down large cuts of meat into smaller parts/pieces to ensure the heat reaches the center of the meat
-
DO NOT COOK whole stuffed food in the microwave. The oven may not heat the stuffing thoroughly
-
After defrosting meat, fish, and/or poultry in a microwave, ALWAYS cook the food IMMEDIATELY
