A.P.H.I.S. will no longer require brucellosis testing for sexually intact bovines imported to the U.S. from British Columbia, Canada, for purposes other than immediate slaughter. This action is based on additional technical and epidemiological information received from Canada after a thorough investigation of the disease situation by Canadian authorities.
Canada quickly identified the herds of origin as part of their investigation; and all animals belonging to those herds over the last year were tested negative for brucellosis or have been otherwise adequately accounted for. No other positive results were found through Canada’s tracebacks.
A.P.H.I.S. concluded the positive results in the original group of reactors may have been due to the presence of cross reactive antibodies detected in the tests used. With the removal of the temporary brucellosis testing requirements, bovines from British Columbia, Canada, may again be imported to the U.S. under the guidelines that applied prior to May 25.
