Transgenic Contamination Prevention (GMO)
The Sonoma County Transgenic Contamination Prevention Ordinance No. 6196R took effect in November 2016. The purpose of the ordinance is to protect Sonoma County’s native plants, trees, and animals from transgenic contamination by genetically engineered organisms. Such organisms are also sometimes referred to as genetically modified organisms or GMOs.
The ordinance makes it unlawful for any person, partnership, corporation, firm, or entity of any kind to propagate, cultivate, raise, or grow genetically engineered organisms in the unincorporated portions of Sonoma County.
