Food waste due to obscure date labeling is a big problem in the US. Efforts are being made to reduce this waste, but consumers need to use their best judgment and available tools until then. So as we’ve said, most expired foods can be safely consumed for varying periods after their sell-by dates.
But that doesn’t mean that a massive chunk of foods won’t go bad EVENTUALLY. When in doubt, use your senses to check if food has gone rotten. If it smells off, feels off, and looks off, chances are it IS!
For example, spoiled milk will have an unpleasantly sour or even putrid smell. Meat that has a pungent, ammonia-type smell developing a green hue and slimy is also rotten. Also, look for discoloration in fruits and veggies or if they’re forming mold.
