MOSA Certified Organic is one of the largest USDA accredited organic certifiers in the United States, and the largest certifier of livestock and dairy. MOSA currently certifies nearly 2000 clients, including over 250 organic processors, distributors, and retailers. We certify and have experience with a wide range of farm and processing types, including market gardens, CSAs, hydroponic and aquaponic, wild crops, greenhouses, mushrooms, orchards, vineyards, dairies, poultry, honey bees, feed mills, abattoirs, brokerages, traders, and food processors of all types. We have the experience you need to access the growing organic marketplace.

MOSA began in 1999 before the National Organic Standards were yet developed and MOSA, like certifiers across the country, used their own set of standards to determine organic qualifications. The National Organic Standards were implemented in 2002, and MOSA was among the very first USDA accredited agencies.

MOSA is a fiscally-sound, stable, and well-respected nonprofit certification agency. We are a strong voice in the organic industry, and we work in partnership with the Accredited Certifiers Association, the National Organic Program, the National Organic Standards Board, Organic Materials Review Institute, and others. We were created by farmers to serve the organic community in a practical, friendly and affordable way. MOSA is headquartered in Viroqua, WI and serves the Midwest, Plains, Mideast, Northeast, Southeast, and South-Central US.

We are your partner in organic success.
