Should Garlic Have Brown Spots?
Shortly after purchasing your garlic from the supermarket, you may begin to notice brown patches all over its surface. These patches are usually raised and medium to dark brown in color. They are reminiscent of the black mold patches that you sometimes find on onions.
However, unlike with onions, these patches are not mold. Instead, they are the scars from bulb mites. These tiny mites leave between the papery layers of the garlic bulb and slowly eat away at the garlic. As they do this, it leaves scars in the garlic that cause small, raised brown patches.
Is It Still Safe to Eat?
Fortunately, even if your garlic bulb is covered with scars from bulb mites, they are still safe to eat. The insect itself is not toxic and as long as you remove a few of the outer layers, you will be able to get rid of the majority of the mites before preparing the garlic.

How to Know if Garlic Is Bad
Outside of brown spots, there are a couple of other things that you should look out for when picking garlic. That way you don’t risk eating garlic that has gone rotten or been contaminated by things like mold.
Look for Visual Signs
The easiest way to tell if your garlic has gone bad is by looking for rotten patches. Rotten patches will typically be brown or black in color and have a soft texture. If you notice patches like this it is time to throw the garlic away.
