Three compliance steps

A

Classify the product

Cultivated fresh is a farm product. Dried goes under the cottage exemption. Foraged and value-added items need extra checks.

B

Control safety

Cultivate in sanitary conditions and dry to 0.85 for cottage sales. Keep mushrooms cold and clean in the market.

C

Label and sell

Dried mushrooms follow the cottage label and registration rules. Fresh mushrooms are exempt from sales tax.

Frequently asked questions

Can I sell chanterelles I foraged?

Foraged species sold to restaurants or retailers need verified identification. Ask MDA licensing before selling.

Is a mushroom grow kit regulated?

It is a plant or supply product, not food, unless it contains fruiting bodies you sell to eat.

Can I sell oyster mushrooms in oil?

No. Oil-packed low-acid foods are outside the cottage law.
