Yes, you may sell meats at a farmers market, if the market rules allow it. Tell the Market Manager you want to start selling meats, and ask what kind of storage is required by market rules. Most of the time, chest coolers are acceptable, however some markets require that you store meats in a small chest freezer run by electrical power. There may be fees associated with using electrical power at the market. If you want to sell fresh meats, be sure to ask if this is allowed as some markets only allow frozen meats to be sold. As with all meat sales, the meat must be processed at a state– or federally-inspected facility and must be properly labeled by the processor. It is also a good idea to recommend that customers bring their own coolers to transport the meat home safely.
