Food can transmit disease from person to person as well as serve as a growth medium for bacteria that can cause food poisoning.

8 S TORAGE F OODS  Procress  Refrigerate perishable food within 2 hours (1 hour when the temperature is above 90 °F).  Check the temperature of your refrigerator and freezer with an appliance thermometer.  Cook or freeze fresh poultry, fish, ground meats, and variety meats within 2 days; other beef, veal, lamb, or pork, within 3 to 5 days.  Perishable food such as meat and poultry should be wrapped securely to maintain quality and to prevent meat juices from getting onto other food.  To maintain quality when freezing meat and poultry in its original package, wrap the package again with foil or plastic wrap that is recommended for the freezer.  In general, high-acid canned food such as tomatoes, grapefruit, and pineapple can be stored on the shelf for 12 to 18 months. Low-acid canned food such as meat, poultry, fish, and most vegetables will keep 2 to 5 years — if the can remains in good condition and has been stored in a cool, clean, and dry place. Discard cans that are dented, leaking, bulging, or rusted.
