Don't sniff the moldy item. You don't want respiratory trouble. If food is covered with mold, discard it. Clean the refrigerator, if necessary, where the food was sitting. Check nearby items it might have touched.
Mold spreads quickly in fruits and vegetables.
If the food shows only a tiny mold spot, follow these guidelines. Generally, we suggest that you can save hard or firm foods with only minor mold problems, but most soft or liquid foods showing mold should be discarded. Some cheese is made with mold, but you may spot mold that shouldn't be there. In hard block cheeses, cut off at least an inch around and below the mold spot. Keep your knife or instrument out of the mold itself.
