MRLs for Trifloxystrobin, proposed by the Pest Control Products Act, from Health Canada’s Pest Management Regulatory Agency (PMRA) for foods imported to and sold in Canada have been adopted by the WTO. The MRLs entered into force on October 15, 2018.

Maximum residue limits (MRLs) for Trifloxystrobin proposed by Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA), for food imported to and sold in Canada have been adopted by the World Trade Organization (WTO). The MRLs entered into force on October 15, 2018. To comply with this Canadian regulation, users can access and check the updated MRLs [1].

Trifloxystrobin (Methyl (2E)-2-methoxyimino-2-[2-[[(E)-1-[3-(trifluoromethyl)phenyl] ethylideneamino] oxymethyl] -phenyl]acetate)(CAS # 141517-21-7) is a white powder. It is the main active ingredients for treating downy and powdery mildews that can be present in agricultural commodities. It can be harmful. Prolonged exposure to it, or frequently repeated skin contact may cause allergic reactions in some individuals.

Pesticide residues in foods are potentially toxic to human health, therefore, the presence of Trifloxystrobin in crops is increasingly monitored in many countries. Recently, the proposed Canadian MRLs for Trifloxystrobin shown in Table 1 [2] were notified to the World Trade Organization (WTO) in accordance with its Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement).

Table 1 Proposed Maximum Residue Limits for Trifloxystrobin

Common Name Commodity               Parts per million
Trifloxystrobin Hops (dried) 40 To be added the list of MRLs
Radish tops 30 To replace the currently established MRL of 10 ppm
Stone fruits  
(Crop Group12-09)
2.0 To be extended to include all commodities in Crop Group 12-09
Radish roots 0.4 To replace the currently established MRL of 0.1 ppm

Benefits of the Proposed MRLs

Businesses benefit from the proposed MRLs because the notification clarifies existing regulation and provides guidance for those that choose to determine the anticipated exposure level for users of a food commodity in order to take advantage of established safe harbor levels. The notification will contribute to public health and safety by providing additional guidance to businesses about how to calculate the level of exposure to Trifloxystrobin residues that may causing reproductive toxicity in a food commodity for the purpose of determining whether a warning is required under the Pest Control Products Act (PCPA). Therefore, this will benefit residents by ensuring that warnings are provided for significant exposure to reproductive toxicants, thereby improving people’s ability to make informed decisions concerning the foods commodity products (those not listed in Table 1) they may choose to purchase.
