Consultation on tolfenpyrad, Proposed Maximum Residue Limit PMRL2023-40

Health Canada is consulting the public and seeking your feedback on proposed maximum residue limit (MRL) increases for tolfenpyrad on imported arugula, garden cress and upland cress; MRL decreases for tolfenpyrad on imported citrus oil and citrus fruits; and new MRLs on other various imported food commodities. An MRL is the highest amount of a specific pesticide residue allowed on a particular food commodity when a pesticide is used according to label directions. These new and revised MRLs are being requested in Canada to align with the United States of America. This is so these various food commodities, or any processed foods derived from these food commodities, can be imported and sold in Canada.

Tolfenpyrad

• Tolfenpyrad is an insecticide not currently registered for use in Canada, and as such there are no associated Canadian labels or uses.
• Food commodities treated with tolfenpyrad were first allowed for importation into Canada in 2016.

What is the proposed MRL decision

• This consultation is on the proposed decision to accept the requests to:
• Increase the MRLs for tolfenpyrad from 30 ppm to 40 ppm on imported arugula, garden cress and upland cress;
• Decrease the MRLs for tolfenpyrad from 70 ppm to 30 ppm on imported citrus oil, and 1.5 ppm to 0.8 ppm on imported citrus fruits (crop group 10 revised); and
• Add new MRLs on various imported food commodities.
• Results from the scientific evaluation show that the proposed new and revised MRLs for tolfenpyrad would continue to meet Health Canada's requirements for the protection of human health.

Reporting to the people of Canada

Health Canada will make the results of this consultation available on this website. Once the decision on tolfenpyrad is finalized, the established MRLs will be legally in effect as of the date that they are entered into the MRL database. The MRL database is an online application that allows users to search for established MRLs, regulated under the Pest Control Products Act, for pesticides and food commodities.
