4、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 food for humans or other animals. The carcass was, however, sent to
5、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 Shirley McClellan, Albertas agriculture minister at the time. “We hav
6、e 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 countries from imposing temporary import bans of Canadian beef. Quick
7、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 have risen from 100,000 tons to about 500,000 tons. Growth in export
8、s 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 for the disease. No other cows were found to have BSE until late D
9、ecember 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 ranchers held barbeques across Canada to help pro mote Canadian beef. In
10、 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 approve a mass slaughter of 620, 000 cattle to reduce the size of t
11、he 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 BSE in a cow in Washington State. Several countries banned beef fr
12、om 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 30 months of age and dairy products. DNA evidence later revealed
13、 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 resume March 7, 2005. The new classification means the U. S. will
14、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 considered a safe country for cattle exports. The move came less
15、 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 injunction to stop the reopening of the border. The ban came at t
16、he 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 countrys second known case of BSE, in a Texas-born cow. On July 14, 2005
17、, 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 “immediately“ open to live Canadian cattle. The British connection Prev
18、iously, 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 mates. Mexico, one of the largest importers of Canadian beef at the t
19、ime, 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 possible human health implications circulating in Britain, the Mi
20、nistry 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, 363 animals were destroyed and their owners compensated. Some sa
21、id 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 of CJD and five others were infected but still living. During the
22、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 carrier of a gene linked to a hereditary form of CJD. In August 2002, d
23、octors 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 had an endoscopic examination before he died and that equipment
24、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 them. Its still not known if the disease can be transmitted through
25、 blood products. 2 The passage gives an overview of how Mad Cow Disease has affected the world in recent years. （ A） Y （ B） N （ C） NG 3 Shirley McClellan appears to believe that having a way of dealing with the disease is more important than whether there are isolated incidents of it. （ A） Y （ B） N
