How to Interpret Expiration Dates
Interpreting expiration dates involves considering multiple factors, including the type of date (best before, use by, or sell by) and the sensory evaluation of the food’s quality. Here are a few methods to help you determine if a product is still safe to consume:
Smell Test
Sniffing the food can often reveal signs of spoilage, such as a sour or unpleasant odor. Trust your nose, as it can detect certain changes that may not be apparent visually.
Look Test
Inspect the food for any unusual changes in color or texture. Discoloration, mold growth, or slimy textures may indicate spoilage.
Taste Test
If the product passes the smell and look tests, you can conduct a small taste test to ascertain its quality. If the flavor is off or tastes rancid, it’s best to avoid consuming it.
While these tests can provide some guidance, it is important to note that if you have any doubts or if the food shows signs of spoilage, it is safer to discard it.
