Excerpt from Ecoholic
“The CFIA [Canadian Food Inspection Agency] says no poultry can be injected with hormones in this country, so that part of the claim is kind of useless (beef cattle are the only animals that can be treated with growth hormones in Canada). As for antibiotics, the CFIA says even conventional birds shouldn’t be shipped ot the slaughterhouse until they test clean for drugs. If the product is federally registered, this label will be pre-approved for accuracy. If it’s provincially registered, it’s open to spot checks or complaint-driven inspections.”
From the US Department of Agriculture
“No hormones are used in the raising of chickens.
Antibiotics may be given to prevent disease and increase feed efficiency. A “withdrawal” period is required from the time antibiotics are administered before the bird can be slaughtered. This ensures that no residues are present in the bird’s system. FSIS randomly samples poultry at slaughter and tests for residues. Data from this monitoring program have shown a very low percentage of residue violations.”
