How Long Do Fast Food Condiments Last?
POSTED: 3:26 pm CDT July 18, 2006
If you open your desk drawer at work, you might find tons of packets of mayonnaise, mustard and ketchup being saved for later.
Most of those packets do not have expiration dates, and you usually can't see what is inside.
How do you know when they go bad?
