Zuckerbrot pointed out a surprising fact: with the exception of baby food and infant formula, dating is not required by U.S. federal law.

So how do you know what is good and what is not safe to eat?

Zuckerbrot shared how these food products are labeled and how long it's safe to eat them:

Poultry and Meat

Meat and poultry typically have a Sell-By date. You should use or freeze your chicken within one to two days of purchasing and meat within three to five days of purchasing. Freezing your poultry and meat can make these proteins last anywhere from nine to 12 months. When freezing, it is important to make sure your poultry and meat is tightly wrapped in order to prevent it from freezer burn. Freezer burn does not make food dangerous to eat, but does damage the texture and taste.

Dairy and Eggs

Dairy and eggs typically have a Sell-By Date

Proper refrigeration (40° F or below) is vital to ensure the best possible shelf life of your dairy.
