Chemical Trespass in our context is defined as any USDA NOP prohibited substance and/or restricted use pesticide, herbicide, fungicide, or insecticide that intentionally or unintentionally causes a positive contamination event.

The presence of prohibited pesticides in organic products must be less than the allowed threshold set by the USDA NOP. The National Organic Program defines residues as “too high” when they are greater than 5 percent of the EPA’s tolerance for the pesticide. See the Resources page for more information.
Pesticides are regulated under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Under FIFRA, the state has primary enforcement responsibility.
GMO contamination is the positive transfer of engineered genes to wild or cultivated versions of the same plant by intentional or unintentional events. Transgenic (aka genetically modified) crops is the primary source of genetic contamination to organic crops.
