How you handle these instances depends on the bang out of cheese youre dealing with.

Why do some cheeses have visible mold?

Mold is often what helps cheese develop its unique flavor and characteristics.

Johnson said eating these cheeses, mold and all, is perfectly safe.

The growth should be uniform, the same color and incorporated into the cheese.

In contrast, new, unwanted mold usually appears on the outside edges only, Craig said.

It may also be a different color and texture and will likely be sporing and fuzzy.

It most likely wouldnt make you sick, though, Johnson said.

It just wouldnt taste very good.

Soft cheeses, like ricotta or cottage cheese, are a different story.

A few signs that cheese isnt safe to eat.

Cheese is generally a safe product, Johnson said.

In those cases, throw the hunk of cheese away.

For instance, pay attention to color or texture changes, sliminess or a watery residue.

Soft cheeses usually last about a week after opening the package.

Png recommended storing cheese in the crisper drawer of your refrigerator, ideally wrapped incheese paperor wax paper.

This can keep moisture out, which might encourage unwanted mold growth.

She said using a plastic container or plastic wrap can trap moisture in.

A plastic zip-top bag can work, too, Johnson said.

But, if you have a way to vacuum seal your cheese, thats a better option.

Every few days, take a look at your cheese, she recommended.
