Dear Stakeholder:

The Veterinary Drugs Directorate (VDD) of Health Products and Food Branch, Health Canada is considering regulatory amendments which may be of interest to your organization. As the designated contact person of your organization, I would appreciate your collaboration in distributing this information to the attention of all interested parties in your organization to solicit their comments.

More specifically, the Veterinary Drugs Directorate is proposing to establish Maximum Residue Limits (MRLs) in Table III to Division 15, Part B of the Food and Drug Regulations for Eprinomectin in edible tissues of food producing animals and milk as indicated in the following table:

Column I Common Name (Or Brand Name of Drug)	Column II Name of Substance for the Drug Analysis Purpose	Column III MRL PPM	Column IV Foods
Eprinomectin	Eprinomectin B1a	0.1	Muscle of cattle
		1.0	Liver of cattle
		0.02	Milk

Eprinomectin is used in beef and dairy cattle to control most GI nematodes and lungworms and also is effective against biting and sucking lice, chorioptic mange mites, cattle grubs, and horn flies. Eprinomectin shows broad-spectrum activity against both endo- and ecto-parasites while leaving minimal residues in meat and milk.

The result of our Health Risk Assessment shows that residues at the above noted concentrations will not pose any undue health risk for consumers. These proposed MRLs will be published in the Canada Gazette, Part I, after consideration of comments from stakeholders.

I would appreciate receiving your comments on this proposal by June 19, 2004. Comments should be sent to the attention of Dhurata Ikonomi, Public Involvement Officer, at the above noted address.

Thank you for your cooperation in this matter.

Yours sincerely,

Diane Kirkpatrick
Director General
