Quick Answer
Identify spoiled food by checking for visible signs of mold, slime, or a sour smell; feel for slimy texture; and check expiration dates. If in doubt, err on the side of caution and discard the food.
Visual Inspection
When inspecting food for spoilage, use your senses, not just sight. Check for visible mold growth, which can appear as green, black, or white patches. Slime or a slimy texture on the surface or in cuts is another clear indication of spoilage. Even if food looks okay, if it’s past its expiration date, it’s best to discard it. For perishable items like dairy, eggs, and meats, check the expiration dates and use your best judgment. When in doubt, err on the side of caution and discard the food.
Smell and Texture
A sour or unpleasant smell is a strong indication that food has gone bad. Check the texture by cutting into the food. If it’s slimy, soft, or has an unusual texture, it’s likely spoiled. For example, a soft or slimy texture on cooked meat is a clear sign of spoilage. Always use a clean knife and cutting board to prevent cross-contamination.
Special Cases
Some foods, like canned goods, can be more difficult to inspect for spoilage. Check the cans for signs of leakage, rust, or dents, which can indicate spoilage. Also, check the expiration date on canned goods. If you’re unsure about the safety of canned food, it’s best to discard it. Remember, when in doubt, discard the food to avoid foodborne illness.
