2、 Cow Disease in Canada For years, Canada had been virtually free of mad cow disease. But in May 2003, veterinary officials in Alberta confirmed that a sick cow sent to a slaughterhouse in January of that year had been inspected, found to be substandard, and removed so that it would not end up as foo
3、d for humans or other animals. The carcass was, however, sent to a processing plant for rendering into oils. Its head was kept for testing. Samples were sent to the world testing laboratories in the U. K. , which confirmed the case of mad cow. “What is important is that the system worked,“ said Shir
4、ley McClellan, Albertas agriculture minister at the time. “We have a very thorough and respected inspection system.“ She was insistent to remind the public that the disease is not contagious within a herd. But McClellans assurances didnt stop the U. S. , Japan, South Korea, Australia and other count
5、ries from imposing temporary import bans of Canadian beef. Quick Facts Canada has close to 13.5 million cows and calves. About 5.7 million (or 42 percent) are in Alberta. Canadas total beef exports amount to $ 2.2 billion annually, and have risen sharply in recent years. Since 1991, beef exports hav
6、e risen from 100,000 tons to about 500,000 tons. Growth in exports has been greatest to Japan, South Korea and Mexico. Albertas share of total beef exports is 39 percent (worth about $ 860 million a year). In an investigation into the source of the infection, 1,400 cows were slaughtered and tested f
7、or the disease. No other cows were found to have BSE until late December 2004. Western premiers demanded $ 360 million compensation from the federal government for losses to the beef industry because of the mad cow scare. Ottawa would later offer $190 million. Over the summer of 2003, cattle rancher
8、s held barbeques across Canada to help pro mote Canadian beef. In August, the U. S. reopened its borders to some Canadian beef, but the border was still closed to live cattle. By this time, a cow that would have normally sold for $1,300 was selling for $15. Canadian beef producers asked Ottawa to ap
9、prove a mass slaughter of 620, 000 cattle to reduce the size of the herd and prevent further damage to the industry. In October, it was reported that the border would reopen to live cattle in December 2003. But on Dec. 23, 2003, the U. S. announced that it had discovered its first apparent case of B
10、SE in a cow in Washington State. Several countries banned beef from the U. S. soon after the announcement, but Canada restricted imports only on some products made from cattle and other ruminants. It still allowed the import of cattle destined for immediate slaughter, boneless beef from cattle under
11、 30 months of age and dairy products. DNA evidence later revealed that the cow was born in Canada, and the U.S. kept its border shut to live Canadian cattle. On Dec. 29, 2004, The USDA announced that it recognized Canada as a “minimal-risk region“ for BSE and imports of young Canadian cattle would r
12、esume March 7, 2005. The new classification means the U. S. will not again close its borders to Canadian beef unless there are two or more cases of BSE per one million cattle older than 24 months of age in each of four consecutive years. Simply put, Canada can have up to 11 cases of BSE and still be
13、 considered a safe country for cattle exports. The move came less than a month after U. S. President George W. Bush made his first official visit to Canada and said the process for reopening the border was underway. However, five days before the ban was to be lifted, a U. Sjudge granted a temporary
14、injunction to stop the reopening of the border. The ban came at the request of a group of American ranchers called R-CAI.F, who filed a lawsuit saying reopening the border would cause irreparable damage to the U. S. beef market. In June 2005, the U. S. Department of Agriculture confirmed the country
15、s second known case of BSE, in a Texas-born cow. On July 14, 2005, a three-judge panel of the U. S. Ninth Circuit Court of Appeals overturned a temporary injunction that banned importation of Canadian cattle. U.S. Agriculture Secretary Mike Johanns announced that day that the U. S. border was “immed
16、iately“ open to live Canadian cattle. The British connection Previously, Canada had only one case of a cow infected with BSE. The animal, reported on a farm near Red Deer, Alberta. , in December of 1993, was imported from Britain. Agriculture Canada opted to destroy the animal and its five herd mate
17、s. Mexico, one of the largest importers of Canadian beef at the time, temporarily banned imports of Canadian cattle after the incident. The United States, another major consumer of Canadian beef, sent observers to Canada to see how the incident was handled. As a result, and because of the rumors of
18、possible human health implications circulating in Britain, the Ministry of Agriculture decided to destroy any animal imported from Britain between 1982 and 1990, the year a ban was placed on British beef imports to Canada. This slaughter also included the offspring of any of those animals. All told,
19、 363 animals were destroyed and their owners compensated. Some said the destruction was unnecessary, especially the farms whose cattle were killed, but the ministry said it was better to err on the side of caution after seeing what was happening in Britain. As of January 2005, 148 Britons had died o
20、f CJD and five others were infected but still living. During the summer of 1995, the disease surfaced again. The Canadian Red Cross Society revealed two of its donors had died of Creutzfeldt-Jakob disease, CJD. Two years later, concern over blood was raised again after a man was found to be a carrie
21、r of a gene linked to a hereditary form of CJD. In August 2002, doctors confirmed a man in Saskatchewan died from new variant CJD - the human counterpart to mad cow disease. He had spent some time in the United Kingdom and it appeared he acquired the disease while he was there, doctors said. The man
22、 had an endoscopic examination before he died and that equipment was then used on other patients. However, because of disinfection and cleaning procedures, the risk of cross contamination is minute. Public health officials phoned patients who had received examinations with the endoscope to inform th
23、em.
