Consuming leftovers or discarding them within a couple of days of preparation ensures there is not enough time for mold to become a problem.

The USDA recommends discarding most foods where mold is growing. Notable exceptions include hard cheeses and firm fruits and vegetables. For these foods, it is still necessary to cut at lease an inch around and an inch below the mold before consuming them. Cured meats, including salami and dry cured hams also sometimes grow mold, but on these products, washing the mold away is all that is necessary.
