Maximum Residue Limits (MRLs)

An MRL is the maximum admissible concentration of a pesticide in or on a food. In the United States, these allowable residues are called tolerances. Only foods that meet MRLs may be placed in the market. Customers in key export markets are paying more attention to the pesticides used and residues present on produce, including almonds.

The International Maximum Residue Limit Database provides a list of MRL tolerances by active ingredient and export market. The Almond Board of California (ABC) provides data and background information to USDA and individual countries when needed to ensure the pesticides almond growers and handlers typically use are present and accounted for on export market lists. In addition, the ABC provides data and background information when necessary to Codex Alimentarius, which sets international standards for food moving in international trade as opposed to each country setting its own standard. Codex MRLs are widely used in many export markets.
