It is normal for hazel mushrooms to have bugs on them. Only small diced mushrooms, or mushrooms that are eaten when they come out, are basically free of bugs. This kind of mushrooms existed on the mountain where my family used to live. It doesn't matter, the bugs are not poisonous. If you want to save it, you can take it out to dry in the sun, and the bugs will crawl out on their own. If you want to use it soon, just wash it with hot water and wash it several times. . .
