Additional DNA testing continues at this time involving the heifer calf on the index farm which was born from this positive cow. Breeding records on that calf confirm that the animal was born from the cow bearing the tag number found at slaughter and found in the records on the farm in Alberta.
This new DNA information, coupled with the documentation that USDA has obtained from its colleagues in Canada, the owner of the dairy farm in Mabton, Washington, and from import records, further increases USDA's confidence in the accuracy of this traceback. Other elements of the investigation continue on both sides of the border and may provide additional information. This includes the cattle feed investigation in Canada as well as the additional DNA testing.
As a point of clarification, on USDA's technical briefing call this afternoon in conjunction with the Canadian Food Inspection Agency, Canada's Chief Veterinary Officer, Dr. Brian Evans, commented that 17 young stock from the BSE-infected animal's birth herd also arrived in the United States as part of a later shipment. USDA and Canadian officials are currently working to confirm if any or all of these 17 animals-all heifers-did in fact enter the United States.
In another important development, USDA personnel began the process of depopulating the bull calf operation outside Sunnyside, Washington, this morning. Approximately 450 calves have been transported from the farm to a designated slaughter facility to be euthanized according to American Veterinary Medical Association guidelines.

On December 23, 2003, USDA's Food Safety and Inspection Service (FSIS) issued a Class II recall of approximately 10,410 pounds of raw beef that may have been exposed to tissues containing the infectious agent that causes BSE. FSIS' designation of the recall as Class II was due to the extremely low likelihood that the beef contained the infectious agent that causes BSE. According to scientific evidence, the tissues of highest infectivity are the brain, spinal cord, and distal ileum. All were removed from the rest of the carcass at slaughter. Therefore, the meat produced were cuts that would not be expected to be infected or have an adverse public health impact. The recall is being conducted out of an abundance of caution.
- FSIS is continuing its around the clock investigation and has determined the points of distribution for all of the recalled product.
- All of the primary, secondary and tertiary establishments that may have received product subject to this recall have been contacted by FSIS compliance officers. All have acknowledged being contacted about the recall by their suppliers. All have confirmed securing whatever product they had upon notification of the recall and making their customers aware of the recall as well.
- FSIS will now focus its efforts toward verifying the return and destruction of the recalled products.
- Recall effectiveness checks have determined that product was sent to six states. Those states are Washington, Oregon, California, Nevada, Idaho and Montana. Alaska, Hawaii and Guam did not receive any of the products subject to recall.
