Based on an analysis of seven years of BSE surveillance data, the USDA has concluded that the prevalence of the disease is less than 1 case per million adult cattle. Because of the low level of the threat, it plans to pull back on its surveillance program.
Based on an analysis of seven years of BSE surveillance data, the USDA has concluded that the prevalence of the disease is less than 1 case per million adult cattle. Because of the low level of the threat, it plans to pull back on its surveillance program. The USDA will continue collecting samples from a variety of sites and from cattle populations where the disease is most likely to be detected. Ongoing surveillance efforts will still cost about $17 million a year.
