[单项选择] Mad 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 food 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.

[简答题] Cereal stocks to decline again in 2003/04
A
6 April 2004, Rome-Global cereal stocks will fall sharply again by the end of the 2003/2004 season, FAO said today. The forecast came in the UN food agency’’s Food Outlook, a publication of the Global Information and Early Warning System. Closing inventories are expected to be down by 89 million tonnes, or 18 percent from their opening levels.
The anticipated sharp decline in cereal stocks from the previous season would be mainly due to China, although substantial reductions are also anticipated in India, Russia, Ukraine and the European Union, mostly driven by the reductions in their 2003 cereal production, says the report.
B
However, the report says world cereal production in 2004 is forecast to increase to 2,130 million tonnes, some 2 percent up on last year and 3 percent above the average of the past five years and that could help alleviate the tight global supply situation in the new 2004/2005 sea
