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 1,3-dichloropropene in or on grapes to permit the import and sale of foods containing such residues.

1,3-Dichloropropene is a nematicide not currently registered for use in Canada.

The PMRA has determined the quantity of residues that are likely to remain in or on the imported food commodities when 1,3-dichloropropene is used according to label directions in the exporting country. The Agency has also determined that such residues will not be a concern to human health and is proposing to legally establish a corresponding MRL. 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.

Details regarding the import MRL application can be found in the corresponding Evaluation Report available in the Pesticides and Pest Management section of Health Canada's website, under Public Registry, Pesticide Product Information Database.^{Footnote 1}

Consultation on the proposed MRL for 1,3-dichloropropene is being conducted via this document (see Next Steps).

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 the  Standards Council of Canada.

The proposed MRL in Canada for 1,3-dichloropropene is as follows.

Table 1 - Proposed Maximum Residue Limit for 1,3-Dichloropropene

Common Name	Residue Definition	MRL (ppmTable 1 footnote 1)	Food Commodity
Table 1 footnotes Table 1 footnote 1 ppm = parts per million Return to table 1 footnote 1 referrer
1,3-Dichloropropene	1,3-dicloro-1-propene, including the metabolites (2Z)-3-chloro-2-propen-1-ol, (2E)-3-chloro-2-propen-1-ol, (2Z)-3-chloro-2-propenoic acid, (2E)-3-chloro-2-propenoic acid	0.018	Grapes

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 food commodities.

International Situation and Trade Implications

The MRL proposed for 1,3-dichloropropene in Canada is the same as the corresponding tolerance established in the United States (tolerances are listed in the  Electronic Code of Federal Regulations, 40 CFR Part 180). Currently, there are no Codex MRLs^{Footnote 2} listed for 1,3-dichloropropene in or on any commodity on the Codex Alimentarius  Pesticide Residues in Food webpage.

Next Steps

The PMRA invites the public to submit written comments on the proposed MRL for 1,3-dichloropropene 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 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.
