Can you eat mushrooms raw?
Better not. The Voedingscentrum (Dutch Nutrition Centre) advises against eating mushrooms raw: harmful bacteria such as listeria may be present, and they contain agaritine, which is partly broken down by heating. So always cook your harvest.

Voedingscentrum · BO-02Shiitake: skin rash
Raw or undercooked shiitake can cause an itchy, streak-shaped skin rash in some people (flagellate dermatitis). According to ANSES, a quick stir-fry is not always enough; Mushroom Mania advises about 20 minutes of boiling or heating.

In the US, enoki has been linked to Listeria outbreaks. The CDC advises heating enoki thoroughly, keeping raw enoki separate from ready-to-eat food and cleaning hands, containers and surfaces after contact. Pregnant people, people over 65 and people with a weakened immune system are most at risk.

After an outbreak in Montana in 2023, 51 people fell ill after eating cultivated morels; eating them raw was most strongly linked to falling ill.
