Michigan's Cottage Food Law, PA 113 of 2010, exempts a "cottage food operation" from the licensing and inspection provisions of the Michigan Food Law. Under this law, some products can be produced in a home kitchen for direct sale to customers at farmers markets, farm markets, roadside stands or other direct markets. If you have been notified by MDHHS or your local health department that levels of PFOA and PFOS above the state drinking water criteria have been found in your water sample, you should not use your water for preparing cottage foods, unless it is filtered by a system certified to reduce PFOA and PFOS.
