Changes in Brucellosis Test Options for Cattle Exported to Canada

The USDA’s Animal and Plant Health Inspection Service (APHIS) has announced several changes to the brucellosis testing options for breeding cattle exported to Canada, effective September 1st, 2017. Importantly, the standard tube test (STT) and standard plate test (SPT) will no longer be accepted by Canadian Food Inspection Agency (CFIA). In addition, the Buffered Acidified Plate Antigen (BAPA) and competitive ELISA tests will be accepted as new options by CFIA. The florescence polarization assay (FPA) test will continue to be accepted.

CFIA has confirmed they will accept the new option BAPA and cELISA tests effective immediately, in order to facilitate this transition in testing options. This acceptance will be reflected on import permits issued from CFIA.
