All fungi sold as wild, fresh foraged fungi to chefs/restaurants and grocery stores in Wisconsin must be free of rot, notable bug damage, and brushed of major debris before sale. No processing, however, is allowed. Only those with certified kitchens and any other relevant licenses may process foodstuffs for sale. The fresh wild foraged fungi will have been harvested with a judicious clean cut, collected in an breathable, clean container such as a basket or loose paper bag, unmixed with any other fungi collections, "field dressed" with debris brushed off and checked for hidden creatures to be removed. The collected fungi will be swiftly removed to a cool, dry, dark clean place for temporary storage before sale within 7 days of harvest.
Fungi will not be kept in "the danger zone" of 32 degrees F to 135 degrees F (including room temperatures) for any appreciable time between harvest and sale.
Fresh fungi will also not be stored fully frozen before sale.
The Wisconsin Wild Mushroom Statement of Sale form will be filled out for each fungi collection sold in full and will be kept with that collection including after sale. The form will be given by the wild fungi seller to the restaurant or grocery store that purchases the fungi.
The form will be retained at least until 90 days after the fungi in the collection have been sold to consumers. These forms will be kept legible and available to any health inspectors or other government personel. All certified identifiers are advised to be ready to participate in investigations into incidents with adverse outcomes to eating the wild foraged fungi they have sold, if any occur.
Certified identifiers may identify fungi collections for sale that were collected by other individuals, but must be doing so while confident of their identifications. Some species may be identified readily without the context of being present at the moment of collection in the wild, others will require that environmental context. The certified identifier must use her or his own judgement in lending identifying services to collections not made in person that will be sold to restaurants or grocery stores. The certified identifier is also in those cases responsible for ensuring the collections are stored properly in the maximum of 7 days before sale and that the statement of sale form is correctly filled out and given to the purchaser with sale. The certified identifier's own name will appear on the form as the identifier, and the different individual who was the collector will also be recorded.
