Shiitake dermatitis
Raw or undercooked shiitake can rarely trigger an intensely itchy, whip-like rash. A systematic review found most cases after raw or lightly cooked shiitake.[1]
Can soaking water be used?
With a clean product it can be used in cooking, but it should be finely filtered and cooked. Discard products with mould, musty odour or unusual cloudiness.
FAQ

No.
