MEAT:If opening the refrigerator door causes stray animals from a three block radius to congregate outside your house, the meat is spoiled.

Flour is spoiled when it wiggles.
It never spoils.
Bibb lettuce is spoiled when you can't get it off the bottom of the vegetable crisper without Comet. Romaine lettuce is spoiled when it turns liquid.

A carrot that you can tie a clove hitch in is not fresh.
Raisins should not be harder than your teeth.
Fresh potatoes do not have roots, branches, or dense, leafy under growth.
