MOSA Organic inspector/certifier

MOSA Certified Organic is the second-largest organic certifier in the United States, and the largest certifier of livestock and dairy. We currently certify nearly 2000 clients in 20 states, including nearly 300 organic processors, distributors, retailers and restaurants. 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.
