US officials don't expect more mad cow cases
US - After the first discovery of mad cow in the United States in 2003, some 700 head of cattle were killed as a precaution. Fears were high that Washington state's cattle market would crater. Federal government experts suggested the industry nationwide could lose $15 billion and others speculated it would not be surprising if a couple dozen infected animals were found. A year and a half later, experts say they have better information about the brain-destroying illness.Source: CTV.ca
