You can search each pesticide tolerance level on the EPA website. Click here for instructions.
For Organic pesticide levels, USDA organic regulation allows for pesticide/herbicide residue due to cross contamination up to 5% of the EPA tolerance for each pesticide on the specific product.
Some testing results will indicate pesticide residues for which EPA has not established a tolerance, and the FDA has not established an action level. Therefore, the USDA Organic limit defaults is 0.01 parts per million (ppm). More info.
