Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) is proposing to establish a maximum residue limit (MRL) for flonicamid on tea (dried leaves) to permit the import and sale of foods containing such residues.
Flonicamid is an insecticide currently registered in Canada for use on various commodities.
The PMRA must determine the quantity of residues that are likely to remain in or on the imported food commodities when flonicamid is used according to label directions in the exporting country, and that such residues will not be a concern to human health. This quantity is then legally established as an MRL on the corresponding imported commodity. An MRL applies to the identified raw agricultural food commodity as well as to any processed food product that contains it, except where separate MRLs are specified for the raw agricultural commodity and a processed product made from it.
To comply with Canada's international trade obligations, consultation on the proposed MRL is also being conducted internationally by notifying the World Trade Organization, as coordinated by Canada's Notification Authority and Enquiry Point.
The proposed MRL, to be added to the MRLs already established for flonicamid, is as follows.
|Common Name||Residue Definition||MRL (ppm)Footnote 1||Food Commodity|
|Flonicamid||N-(cyanomethyl)-4-(trifluoromethyl)-3-pyridinecarboxamide, including the metabolites 4-trifluoromethylnicotinic acid, N-(4-trifluoromethylnicotinoyl)glycine and 4-trifluoromethylnicotinamide||40||Tea (dried leaves)|
- Footnote 1
ppm = parts per million
MRLs established in Canada may be found using the Maximum Residue Limit Database on the Maximum Residue Limits for Pesticides webpage. The database allows users to search for established MRLs, regulated under the Pest Control Products Act, both for pesticides or for food commodities.
International Situation and Trade Implications
Table 2 compares the MRL proposed for flonicamid in Canada with the corresponding American tolerance and Codex MRLFootnote 1. American tolerances are listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide. A listing of established Codex MRLs is available on the Codex Alimentarius Pesticide Index webpage, by pesticide or commodity.
|Food Commodity||Canadian MRL (ppm)||American Tolerance (ppm)||Codex MRL (ppm)|
|Tea (dried leaves)||40||40||Not established|
The PMRA invites the public to submit written comments on the proposed MRL for flonicamid up to 75 days from the date of publication of this document. Please forward your comments to Publications. The PMRA will consider all comments received before making a final decision on the proposed MRL. Comments received will be addressed in a separate document linked to this PMRL. The established MRL will be legally in effect as of the date that it is entered into the Maximum Residue Limit Database.
Summary of Field Trial Data Used to Support the Proposed Maximum Residue Limit
Residue data for flonicamid in tea were submitted to support the maximum residue limit on imported tea.
Maximum Residue Limit
The recommendation for the maximum residue limit (MRL) for flonicamid was based upon the submitted field trial data for tea treated according to label directions in the exporting country, and the guidance provided in the OECD MRL Calculator. Table A1 summarizes the residue data used to calculate the proposed MRL for imported tea.
|Commodity||Application Method/ Total Application Rate
(g a.i./ha)Footnote 1
|Preharvest Interval (days)||Lowest Average Field Trial Residues
|Highest Average Field Trial Residues
|Tea (dried leaves)||Foliar Spray / 200||7||17.6||23.2|
- Footnote 1
g a.i./ha = grams of active ingredient per hectare
Following the review of all available data, the MRL proposed in Table 1 is recommended to cover residues of flonicamid and its metabolites. Residues of flonicamid and its metabolites in imported tea (dried leaves) at the proposed MRL will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.

The Codex Alimentarius Commission is an international organization under the auspices of the United Nations that develops international food standards, including MRLs.
