Quick Answer
Check expiration dates, inspect food packaging for visible signs of spoilage, and use the "smell test" to quickly identify expired food supplies.
Visual Inspection
When inspecting food supplies, look for visible signs of spoilage such as mold, slime, or an off color. Check the packaging for any tears, holes, or damaged seals that could compromise food safety. For canned goods, inspect the lid for any signs of rust or swelling.
Expiration Dates and Codes
Familiarize yourself with common expiration date formats, including “Best By,” “Use By,” and “Sell By.” For food stored in airtight containers or zip-top bags, check the expiration dates on the original packaging. Use a code book or online resource to decipher expiration codes on cans, bottles, and other containers.
The Smell Test
The smell test is a quick and effective way to determine if food has spoiled. For dry goods like flour, rice, and pasta, check for a musty or sour smell. For canned goods, check for a sour or metallic smell. If in doubt, err on the side of caution and discard the food item.
