Food safety rules that apply to every food

Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C).
Never allow meat, poultry, seafood, eggs, or produce or other foods that require refrigeration to sit at room temperature for more than two hours—one hour if the air temperature is above 90° F.
Though food will be safe indefinitely at 0° F, quality will decrease the longer the food is in the freezer.
Never thaw food at room temperature, such as on the counter top. There are three safe ways to defrost food: in the refrigerator, in cold water, and in the microwave. Food thawed in cold water or in the microwave should be cooked immediately.
Perishable foods should never be thawed on the counter, or in hot water and must not be left at room temperature for more than two hours.
If you're not sure or if the food looks questionable, throw it out.
