Are mushrooms “kosher”?
On occasion—most frequently within a number of sectors of the independent Hebrew/Hebraic Roots movement—one will hear a claim made that mushrooms, and by association various other fungi, are unclean or non-kosher. Much of this relates to how mushrooms reproduce. Yet, one need not go too far to realize that mushrooms are a feature of traditional Jewish cooking. This means that at one point in history, Jewish religious authorities decided that mushrooms, even if they do not bear seed (cf. Genesis 1:29) in the more customary sense, may be considered a food product eligible for consumption.
You will find that today’s Messianic Judaism does consider mushrooms to be clean or kosher. Like any food product, though, mushrooms should be thoroughly washed before being eaten. There can also be considerable dangers associated with picking wild mushrooms, as many mushrooms are poisonous. So, sticking with commercially processed mushrooms should be regarded as the safest option for most.[1]
