How long can a food last before it goes bad?

Answer 1

How long a food can last before going bad depends on the food. Cooked meats can be kept in the refrigerator for three or four days. Canned vegetables that are stored in a bowl in the refrigerator will keep for around three days. Canned goods remain good for a year or more.

Answer 2

Actually fertilizer never goes bad. It's required for the fertilizer industries to put an expiration date on the bag. However many people use it well after the expiration date and end up with the same results as a brand new bag of fertilizer would produce.
