About us   

The EPA sets the legal limits for the amount of pesticides allowed in food and drinking water. In food, those limits are called "tolerances." In water, those limits may be called Maximum Contaminant Levels (MCLs), health advisories (HA), or other names. The amount of pesticide allowed in water is specifically regulated for some pesticides, while health advisories are issued for others. For more information on the pesticide limits in water or food, see the resources below.

You can use the eCFR search tool to find tolerances for food published in the Code of Federal Regulations (CFR)

Our tolerance search tool has been discontinued and replaced by a search tool on the federal eCFR page. You can search for active ingredients or food commodities there.
