June 9, 2010: The Canadian Food Inspection Agency (CFIA) has removed quarantines from two British Columbia farms. A thorough investigation did not confirm the presence of brucellosis.
The CFIA launched the investigation after three beef cows from the two B.C. farms were classified as “reactors” (suspect) on brucellosis tests. These tests were done by the United States Department of Agriculture (USDA) during routine slaughter testing. Animals on both farms were tested for brucellosis, all with negative results.
The Agency also completed further analysis of the original samples from the USDA at its internationally recognized brucellosis reference laboratory in Ottawa. These analyses, using more specific tests, found that the original suspicious test reactions observed in the U.S. laboratory appear to have been caused by another bacterium that is known to create false-positive test results.
The USDA continues to apply temporary restrictions on certain cattle and bison from B.C. Until further notice, all sexually intact cattle and bison that have resided in B.C. since March 25, 2010, must test negative for brucellosis, with certification by the CFIA, prior to export to the U.S. This requirement does not apply to cattle and bison exported for immediate slaughter.
Results of the laboratory analyses and investigation have been shared with the USDA. The CFIA is working closely with USDA officials to see that the trade restrictions are lifted as quickly as possible.
