Latest Information
Latest Information (as of April 28, 2006 - 16:00 EST)
The Canadian Food Inspection Agency (CFIA) has identified 23 live cattle potentially exposed to the same feed as the affected animal. These animals have been quarantined and will be tested.
Investigators continue to trace other animals from the feed cohort. To date, a number of animals from this group are known to have been exported to the United States.
Exorted animals were also identified during investigations conducted in 2003 and 2005, which is not surprising, considering the regular cross-border movement of cattle prior to the first detection of BSE in this part of the world.
As was done during previous investigations, Canadian and American authorities are collaborating fully to trace these animals.
Finding additional cases of BSE in a feed cohort is unlikely. Nonetheless, efforts to locate all animals from this group will be carried out to the fullest extent possible.
Consistent with international BSE guidelines, the affected animal’s two most recently born offspring are of interest to this investigation. One of these calves is known to have previously died. The disposition of the other calf remains under investigation.
As part of the feed investigation, the CFIA is examining opportunities for contamination that may have been present during the manufacture, transportation and storage of feeds and feed ingredients.

15 herdmates in mad cow case exported to US

WINNIPEG, Manitoba (Reuters) - The Canadian Food Inspection Agency said on Friday that 15 herdmates of Canada's latest mad cow case were exported to the United States.

The U.S. Department of Agriculture has located one of the 15 animals in Washington State and continues to trace the others, agency spokesman Ed Loyd said.

"We have just under 150 animals that we are tracing ... and 23 were located in Canada and quarantined," said Dr. George Luterbach, senior veterinarian with the CFIA.

The 23 cattle quarantined in Canada, as well as the one located in Washington, will soon be euthanized and tested for bovine spongiform encephalopathy, also known as BSE or mad cow disease.

The animals may have been exposed to the same feed as the six-year-old dairy cow from a farm in the western province of British Columbia that tested positive for the brain-wasting disease.

BSE is believed to be spread by feed containing rendered protein from infected cattle or other ruminants.

"I would stress that even during the highest levels of infectivity of BSE in the European situation there were rarely more than one animal in the herd that would become infected and express the disease," the USDA's Loyd said. "I would think the likelihood of any additional exposure would be extremely remote in the United States."

The Canadian agency's investigation focuses primarily on the cow's birth farm, which is close to the one it was found on, Luterbach said.

The CFIA continues to trace the remaining cohorts, cattle born on the same farm 12 months before or after the affected animal. Luterbach said the agency does not expect to find them all as many would have been killed for a variety of reasons.

"It's not likely any of these would have entered into the human food chain as there are a number of measures that are taken," Luterbach said.

The pure-bred Holstein cow was confirmed to have the disease on April 16, making it Canada's fifth native-born mad cow case. The CFIA said then that it did not enter the food supply.

The animal was born after the 1997 ban that prohibited adding protein from cows and other ruminants, such as goats and sheep, to cattle feed.

This is not the first time that mad cow cohorts have been exported to the U.S. This also occurred in 2003 and 2005, the CFIA said in a release.

The agency said it is "unlikely" to find additional BSE cases in the feed cohort.

The CFIA has located the cow's 2004 calf, which had been slaughtered, but continues to search for its 2005 calf as it is believed it may be possible for BSE to be passed to offspring. The cow was pregnant at the time of her death, Luterbach said.

The Canadian cattle industry suffered in 2003, when the U.S. banned imports of live cattle after the first native-born case was confirmed. The importation of cattle under 30 months old resumed in 2005.

AS i said, GSs BSE MRR policy is nothing more than a legal tool that will spread TSE globally, and the OIE went right along with it. nothing more than commodities and futures, had nothing to do with human health or sound science. WE MUST ADHERE TO THE BSE GBR RISK ASSESSMENTS, and enhance them to make them cover all TSE. ...TSS
