Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) is proposing to establish maximum residue limits (MRLs) for carbaryl on dried shelled pea and bean, except soybean (Crop Subgroup 6C), cactus, dry soybeans, flaxseeds, pineapples, rice, sorghum, sunflower seeds and sweet potato roots to permit the import and sale of foods containing such residues.
Carbaryl is an insecticide currently registered in Canada for use on a wide variety of crops.
The PMRA has determined the quantity of residues that are likely to remain in or on the imported food commodities when carbaryl 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 corresponding import MRLs. 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 MRLs can be found in the corresponding Evaluation Report available in the Pesticides and Pest Management section Health Canada's website, under Public Registry, Pesticide Product Information Database.Footnote 1
A Canadian MRL of 5.0 ppm is currently established for carbaryl in or on "Beans" and "Peas". This MRL will remain in effect for each commodity included in the edible-podded
and succulent shelled legume subgroups (Crop Subgroups 6A and 6B). A revised 1.0 ppm MRL is proposed herein for commodities included in the dried shelled pea and bean subgroup (Crop Subgroup 6C).
Consultation on the proposed import MRLs for carbarylis being conducted via this document (see Next Steps, the last section of this document).
To comply with Canada's international trade obligations, consultation on the proposed MRLs is also being conducted internationally by notifying the World Trade Organization, as coordinated by the Standards Council of Canada.
The proposed MRLs for carbarylin Canada in or on food, to replace or be added to the MRLs already legally established, are as follows.
|Common Name||Residue Definition||MRL (ppm)||Food Commodity|
proposed to replace the established MRL of 5.0 ppm in or on "Beans" and "Peas" for all subgroup commodities.
|1.0||Dried shelled pea and bean, except soybean (Crop Subgroup 6C)|
|0.5||Dry soybeans, sunflower seeds|
|0.02||Flaxseeds, sweet potato roots|
Revised MRLs are proposed for each commodity included in the dried legume subgroup in accordance with the Residue Chemistry Crop Groups webpage in the Pesticides and Pest Management section of Health Canada's website.
A complete list of all pesticide MRLs established in Canada can be found on the Maximum Residue Limits for Pesticides webpage in the Pesticides and Pest Management section of Health Canada's website.
With the exception of flaxseeds and sweet potato roots, the proposed MRLs for carbaryl in Canada are the same as the corresponding tolerances established in the United States (tolerances are listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide). Codex Alimentarius MRLsFootnote 2 have been established for a limited number of commodities included in this action. A listing of established Codex MRLs is available on the Codex Alimentarius Pesticide Residues in Food website.
See Table 2 for a comparison of the proposed Canadian MRLs for carbaryl with corresponding American tolerances and Codex MRLs.
|Food Commodity||Canadian MRL (ppm)||American Tolerance (ppm)||Codex MRL (ppm)|
|Rice||15||15||1 (Rice, Polished)
170 (Rice bran, Unprocessed)
|Sweet potato roots||0.02||0.2||0.02|
|Cactus pads||12||12||Not established|
|Cactus fruit||5.0||5.0||Not established|
|Dried shelled pea and bean, except soybean (Crop Subgroup 6C)||1.0||1.0||Not established|
The PMRA invites the public to submit written comments on the proposed import MRLs for carbarylup to 75 days from the date of publication of this document. Please forward your comments to Publications (see the contact information on the cover page of this document). The PMRA will consider all comments received before making a final decision on the proposed MRLs for carbaryland posting a corresponding Established Maximum Residue Limit document in the Pesticides and Pest Management section of Health Canada's website.

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