A feed ban was put in place in 2007 to support animal health, the agency said. It includes restrictions on the use of some fertilizers and supplements and requires that precautionary statements be on labels for fertilizers and supplements that contain prohibited material.
Prohibited material is any item that contains animal protein with a few exceptions, said the agency. The exceptions include pig or horse, milk or milk products, gelatin from hides or skins, blood or blood products and rendered fats containing no more than 0.15% insoluble impurities.
Materials considered of specific risk include those part of a cow that contain the BSE agent, said the CFIA. These products include the “skull, brain, trigeminal ganglia, eyes, palatine tonsils, spinal cord and dorsal root ganglia (DRG) of cattle aged 30 months or older, as well as the distal ileum of cattle of all ages” and the skull of cattle older than 30 months, added the agency.
Additionally, the products cannot be fed to ruminants or spread on land grazed by ruminants, said CFIA. Animal by-products, including poultry manure from birds ingesting prohibited material are still considered to be items that are prohibited and require warning labels.
