BSE Harvard Risk Assessment
In November 2001, USDA released a landmark study by Harvard
University demonstrating that the risk of BSE
occurring in the United States is extremely low. The report
showed that early protection systems put into place by USDA
and HHS
have been largely responsible for keeping BSE out of the United
States and would prevent it from spreading if it ever did enter
the country.
The risk assessment was commissioned by USDA and conducted by the
Harvard Center for Risk Analysis. It evaluates the ways BSE could
spread if it were to ever enter the United States. The report's
purpose is to give agencies a scientific analysis to evaluate preventive
measures already in place and identify additional actions that should
be taken to minimize the risk of BSE.
Despite the positive feedback from the Harvard study, VS
continued to strengthen and bolster U.S. protection systems against
BSE to decrease the risk even further. Accomplishments since then
include the following:
- VS established a goal of 12,500 samples for the year in its
BSE surveillance program.
- VS far exceeded this goal with a record number of more than
19,000 samples.
- The Harvard assessment has been sent out for a peer review.
Four independent scientists have been selected as peer reviewers
by an independent contractor. The peer review should be complete
by the first quarter of fiscal year 2003.
- VS is now testing dead cattle on farms and ranches as part
of its targeted surveillance. Such cattle are considered an important
potential pathway for the spread of BSE in the animal chain.
- APHIS
is drafting an ANPR to consider additional regulatory options
for the disposal of dead cattle on farms and ranches.
