Grocery expiration labels can be intimidating, especially for dairy products and meats.
Manufacturers give their best estimate of when food will reach its peak quality with phrases such as “best before”, “use by” and “sell by”.
But, officially, the USDA says the dates don’t indicate product safety. Only infant formula is required by federal law to be dated.
“Date labels generally indicate when foods will be at their peak freshness,” said Nina Sevilla, an advocate for the food waste program. Natural Resources Defense Council. “If you have food a few days after that date, that probably means you can still eat it.”

Sevilla said the best way to tell if your food has gone bad is through your senses.
“In most cases, your body has a natural, unpleasant reaction to the taste or smell of spoiled food,” she said. “Our reaction to spoiled food is evolutionary. We have honed our senses to protect ourselves from ingesting things that could hurt us.”
To reduce unnecessary waste, the NRDC is federal call to action to standardize food date labels. In the meantime, here’s how to decipher what you might find at the grocery store, as well as how to press pause when ripening with your freezer.
