What's Covered / What Needs More

✓ What's Covered

  • Fresh, commercially cultivated gourmet mushrooms (oyster, shiitake, etc.) sold direct as a raw agricultural product
  • Dried mushrooms sold under the cottage food exemption, following the standard course + labeling requirements
  • Grow-kit or spawn/substrate sales, which are agricultural inputs rather than food products
  • Wholesale of cultivated mushrooms to permitted retailers or restaurants

✕ Needs More

  • Selling wild-foraged mushrooms to the public without absolute species certainty — misidentification risk makes this a serious liability and several states restrict or ban commercial sale of foraged fungi; confirm current HDOH guidance before offering wild species
  • Value-added mushroom products (broths, TCS-style preparations) made and sold without an HDOH permit
  • Skipping the food-safety course when selling dried mushrooms under the cottage exemption
  • Assuming mushrooms are treated identically to produce — HDOH may apply added scrutiny given foodborne-illness history with fungi

How to Get Compliant

A

Confirm cultivated vs. wild-foraged

Commercially cultivated fresh mushrooms generally sell like other fresh produce; wild-foraged mushrooms carry extra liability and possible restriction — verify directly with HDOH before selling.

B

Choose your path for dried product

Dried mushrooms fit the standard cottage exemption: food-safety course plus home-kitchen labeling.

C

Label clearly

Identify the species by common and scientific name, note growing/harvest method, and include standard allergen/ingredient information for any dried blends.

Frequently Asked Questions

Can I sell foraged wild mushrooms at a farmers market?
Check directly with HDOH first — species misidentification risk means wild fungi often face tighter scrutiny or restriction compared to cultivated mushrooms.
Are dried shiitake or oyster mushrooms cottage-eligible?
Yes, dried mushrooms fit the standard cottage food exemption with the usual course and labeling requirements.
Do I need a permit to sell fresh cultivated mushrooms?
Generally no HDOH food permit is needed for fresh, uncut cultivated mushrooms sold as produce, similar to other fresh agricultural products.
Can I sell mushroom grow kits or spawn?
Yes, these are agricultural inputs rather than food products and aren't subject to food permitting.
