02/12/1998. Description of content: Fluazuron is a tick development inhibitor which controls the cattle tick Boophilus microplus, present in tropical areas including Australia. It is not currently registered under the Pest Control Products Act for use in Canada since the product is not manufactured, used or sold in Canada.
The Pest Management Regulatory Agency of Health Canada has been requested to establish Maximum Residue Limits (MRLs) for fluazuron in meat and meat by-products from cattle imported into Canada.
After the review of all available data, it is proposed to amend the Food and Drug Regulations to establish MRLs for fluazuron in fat of cattle at 7.0 ppm and in meat by-products of cattle at 0.5 ppm. Residues of fluazuron in cattle meat will be covered under the general tolerance of 0.1 ppm specified in subsection B.15.002(1).

Evaluation of certain veterinary drug residues in food. Forty-eighth report of the Joint FAO/WHO Expert Committee on Food Additives.

[No authors listed]

This report presents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of residues of certain veterinary drugs in foods and to recommend maximum levels for such residues in food. The first part of the report considers standards for the performance of studies, residues at the injection site, and several initiatives to promote transparency of the process for setting Maximum Residue Limits (MRLs). A summary follows of the Committee's evaluations of toxicological and residue data on a variety of veterinary drugs: two anthelminthic agents (moxidectin and tiabendazole), eight antimicrobial agents (ceftiofur, danofloxacin, dihydrostreptomycin, streptomycin, enrofloxacin, flumequine, gentamicin and spiramycin), one glucocorticosteroid (dexamethasone), and two insecticides (cyfluthrin and fluazuron). Annexed to the report are a summary of the Committee's recommendations on these drugs, including Acceptable Daily Intakes and MRL's and further toxicological studies and other information required.
