OGM is a non-profit USDA accreditated certifying organization of more than 200 organic farmers, gardeners and friends who are interested in organic practices and organically raised food. OGM was established in 1972 and is the second oldest state organic certifying agency in the USA. OGM is organized into six chapters located throughout the entire state of Michigan.



OGM spans the state from Detroit to the western Upper Peninsula. OGM has a certification system that assures the public that our crops and livestock are grown according to strict organic principles. This means that food purchased from OGM certified growers is produced without the use of artificial fertilizers, chemical pesticides, antibiotics, hormones or any synthetic substance.
