Canadian health officials confirmed Thursday that the unidentified man died sometime this summer. The man, who lived in the western province of Saskatchewan, contracted the disease from eating contaminated (污染的 ) meat while traveling in Britain. Dr. Antonio Giulivi, an official with the government agency Health Canada, quickly moved to calm fears by assuring the public the disease had not entered the Canadian food supply. The variant of the cowkilling illness, known as CreutzfeldtJakob disease, is believed to be caused when ground parts of diseased cattle are mixed into cattle feed and those cows are turned into processed meats for human consumption. Though the disease cannot be confirmed until an autopsy (尸體解剖 ) is performed on the dead brain, symptoms of human infection include uncontrolled shaking, dementia (癡呆 ) and finally paralysis (癱瘓 ). But while government officials insisted safeguards are in place to keep the disease out of Canadian meat, warnings were issued to 71 patients at the hospital where the infected man was treated before his illness was identified. Those patients had been treated with the same medical instruments used on the diseased man. Though the instruments were cleaned and disinfected (消毒 ), officials said a theoretical possibility remains that those people could have been infected. News of the death initially sent Canadian restaurant stocks into a tailspin (直線下降 ), but most of them recovered by the end of the trading session. 1.

The airline will continue operations while it seeks a solution to its financial crisis. Based in suburban Washington, US Airways is the first major American airline to declare bankruptcy since the September 11 attacks jolted (震撼、震搖 ) the airline industry.
