Bovine spongiform encephalopathy (BSE) is a progressive and fatal neurological disorder of cattle that results from an unconventional transmissible agent. BSE belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs). Since 1990, the United States has conducted surveillance for BSE in this country with increasing intensity, including an enhanced surveillance effort implemented following the diagnosis of BSE in a cow of Canadian origin in Washington State in December 2003.

The Animal and Plant Health Inspection Service (APHIS) has conducted an analysis of the BSE surveillance data collected in the United States. Based on this analysis, APHIS has arrived at an estimate of BSE prevalence in this country. This information will help to guide and support any future requests for consideration of the overall BSE status of the United States.

We are making our analysis of BSE prevalence in the United States available to the public. This report is considered a draft and will undergo peer review.
