The Napa County Agricultural Commissioner verifies and registers producers of agricultural products who sell directly to the consumer either at the site of production or at a farmer's market.

If you have a culinary garden and wish to sell directly to restaurants or members of the public you mush be an "Approved Source". The concept is simple: Food that will be used to serve the public must be protected from contamination at all staged of the process, and the approval process allows officials to "trace back" a food product to its source if a health-related problem occurs. A grower or gardener who wants to be an approved source must complete the application with Environmental Management. Follow this link for approved source criteria and application.
