TB SURVEILLANCE IN U.S. LIVESTOCK FY 2006

摘要

Surveillance for bovine tuberculosis (TB) in the US consists of slaughter surveillance for granulomas and skin and blood testing in cattle. The national granuloma submission program for adult cattle met or exceeded the target rate of 5 submissions per10,000 adult cattle killed for the fifth consecutive year in fiscal year 2006 (FY2006), with 11.7 granuloma submissions per 10,000 adult cattle killed. A total of 9,334 granulomas were submitted from 195 US plants that slaughtered approximately 32 million cattle, including 5.6 million adult cattle. Of the 195 slaughter plants, 40 plants located in 20 states slaughtered 95.7 percent of all adult cattle and submitted 7,284 (78 percent) granulomas. The estimated submission rate for adult cattle from these40 plants ranged from 2.1 to 29.5 granulomas per 10,000 slaughtered. Compliance with the granuloma submission standard is defined as achieving greater than or equal to 85 percent of the target rate; 37 (92.5 percent) plants met this criteria. Three plants achieved less than 85 percent (83,74 and 52 percent).
