Pictured Recipe: Red Cabbage Salad with Blue Cheese & Maple-Glazed Walnuts
Americans throw away about 90 billion pounds of food every year (yikes!). No one likes trashing their food—and money—but if something in your fridge is starting to turn, how do you know whether it's safe to eat it? If you see mold growing on food in your fridge, do you automatically need to throw it out?
Not always, according to the USDA. Some foods can be used even when they're moldy, while others need to be discarded.

However, if any of these are completely covered with mold, throw them away.
Apparently it's normal for these products to have a surface mold. The USDA's advice is to just scrub the mold off the surface and then use.
For cheeses where mold isn't part of the processing, mold generally can't get deep into the product. For hard cheeses, such as Asiago, Pecorino, Parmesan and Cheddar, lop off at least 1 inch around and below the mold spot (to avoid cross-contamination, be careful not to touch the mold with the knife).
If these cheeses, such as Gorgonzola and Stilton, have a surface mold on them, you can use them if you cut off at least 1 inch around and below the mold spot.
The key word here is firm (think: cabbage, bell peppers, carrots, etc.). Like the hard cheeses made without mold, dense fruits and vegetables are not easily penetrated by mold. The same rule of thumb applies to firm produce: cut off at least an inch around and below the mold spot (again, not touching the mold with your knife) before using.
These foods have a high moisture content and so may be contaminated with mold—which have difficult-to-see, thin, threadlike branches and roots—below the surface.
Cheeses that are made with mold—and aren't hard—such as Brie, Camembert and some blue cheeses, should be discarded. Soft cheeses, such as cottage and cream cheese, Neufchatel, chevre, etc., should also be thrown away. Also ditch all types of crumbled, shredded or sliced cheeses.
According to the USDA, the mold in jams and jellies could produce a mycotoxin (a poisonous substance that can make you sick) and so should be discarded.
Like yogurt and sour cream, soft fruits and vegetables (cucumbers, tomatoes, peaches, berries, etc.) may have mold growing below the surface. Also, because mold spreads quickly in fruits and vegetables, check nearby foods in your produce drawer.
These are porous foods, so mold may also be growing below the surface.
Because these are processed without preservatives, they're at high risk for mold, according to the USDA.
If these items, which are moisture-rich, like yogurt, sour cream and produce, have mold on them, they should be discarded as the mold may also be below the surface.
The USDA advises that you discard cooked leftover meat and poultry, cooked casseroles and cooked grain and pasta that are moldy. They all have high moisture content and, thus, may be contaminated with mold below the surface.
