Molds On Food: Are They Dangerous?

When you can eat things with mold on them.

How Should You Handle Food with Mold on It? Buying small amounts and using food quickly can help prevent mold growth. But when you see moldy food: * Don’t sniff the moldy item. This can cause respiratory trouble. * If food is covered with mold, discard it. Put it into a small paper bag or wrap it in plastic and dispose in a covered trash can that children and animals can’t get into. * Clean the refrigerator or pantry at the spot where the food was stored. * Check nearby items the moldy food might have touched. Mold spreads quickly in fruits and vegetables. * See the attached chart “Moldy Food: When to Use, When to Discard.”

The USDA takes it's stand.
