Food Safety with Ask Wisconsin AnswerLine

Spring pantry decluttering helps prevent pests and makes meal planning easier. Discard items past expiration, foods with off odors, or packaging that shows signs of damage. Donate unopened items that are still safe to food pantries.

Proper refrigerator and freezer temperatures reduce the risk of foodborne illness. Use an appliance thermometer to confirm your fridge is at 40°F or below and your freezer is at 0°F.

Inspecting your storage containers can help prevent contamination and extend food quality. Replace containers that are cracked, warped, or stained, and verify that lids fit securely.

Cleaning and sanitizing kitchen surfaces helps reduce germs that cause illness. Start by washing surfaces with warm, soapy water. Then, sanitize using a diluted bleach solution (1 tablespoon of unscented bleach per gallon of water).
