BSE Ongoing Surveillance Program
FY 2012 Monthly Test Results
APHIS reports ongoing surveillance test totals monthly.
The BSE ongoing surveillance program will sample approximately 40,000 animals each year. Under the program, USDA will continue to collect samples from a variety of sites and from the cattle populations where the disease is most likely to be detected, similar to the enhanced surveillance program procedures.
