Eating Grain Spawn

[nyles]

Every time I go out and innoculate a substrate using my
homemade grain spawn I always end up eating some.
To me it tastes great.
I was thinking about cooking up some second generation
spawn I had laying around (Maitake, Pleurotus and Ganoderma).

Does anyone know if this is safe?
In the case of Maitake and Reishi, do you still derive the medicinal
benefits?

Thanks
