What the USDA adds in words

Word for word from the FoodKeeper record.

In the pantry. Refrigeration ensures that commercial sauces and condiments stay fresh for a longer period of time. Shelf-stable commercial salad dressing is safe when stored at room temperature after opening. Quality, not safety, is the reason the labels on these products suggest that they be refrigerated after opening.

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.
