Refrigerate Promptly Below 40°F
Leftover foods from a meal should not stay out of refrigeration longer than two hours. In hot weather (90°F or above), this time is reduced to one hour.
Freezing is also a smart storage option to extend the shelf life of many perishable foods. Use an appliance thermometer to ensure your freezer is at 0° Fahrenheit or below.
Important tip: WHEN IN DOUBT, THROW IT OUT!
