Poultry's Shelf Life

Packaged poultry should be refrigerated and used within two days or stored in the freezer.

How to Tell If Your Eggs are Fresh or Expired

Place the egg in a pan of cold water. If it sits on its side, the egg is still fresh. If, however, it tilts on an angle, it's past its prime by about three to four days. If the egg stands upright, it's approximately ten days old. If the egg floats to the top, it's really, really old.

Baking Soda Expiration Date

I'm skeptical to trust shelf life guidelines, as they can be outrageously inconsistent and don't account for various factors. The general rule is that baking soda lasts for six months. If you question its freshness or it's been more than six months, you can assess its freshness by adding some vinegar to it. If the baking soda bubbles, it's still good. If it doesn't, it's past its prime. Throw it away.
