fourth case of bovine spongiform encephalopathy (BSE)Mad Cow Disease
“The United States has had longstanding interlocking safeguards to protect human and animal health against BSE. For public health, these measures include the USDA ban on specified risk materials, or SRMs, from the food supply.
SRMs are parts of the animal that are most likely to contain the BSE agent if it is present in an animal. USDA also bans all nonambulatory (sometimes called “downer”) cattle from entering the human food chain. For animal health, the Food and Drug Administration (FDA) ban on ruminant material in cattle feed prevents the spread of the disease in the cattle herd.
Evidence shows that our systems and safeguards to prevent BSE are working, as are similar actions taken by countries around the world. In 2011, there were only 29 worldwide cases of BSE, a dramatic decline and 99% reduction since the peak in 1992 of 37,311 cases. This is directly attributable to the impact and effectiveness of feed bans as a primary control measure for the disease.”
“In addition, we will be conducting a comprehensive epidemiological investigation in conjunction with California animal and public health officials and the FDA.
BSE is a progressive neurological disease among cattle that is always fatal. It belongs to a family of diseases known as transmissible spongiform encephalopathies. Affected animals may display nervousness or aggression, abnormal posture, difficulty in coordination and rising, decreased milk production, or loss of body weight despite continued appetite.
This detection in no way affects the United States’ BSE status as determined by the OIE. The United States has in place all of the elements of a system that OIE has determined ensures that beef and beef products are safe for human consumption: a mammalian feed ban, removal of specified risk materials, and vigorous surveillance. Consequently, this detection should not affect U.S. trade.”
“There is no public health threat due to the discovery of BSE in a dairy cow. The food supply in California has not been affected by this discovery, and residents do not need to take any specific precautions. The California Department of Food and Agriculture has many procedures in place to keep this disease from entering the food chain, and the detection found is evidence that the system of safeguards is working. The cow in question was not slaughtered for food and BSE is not transmitted in milk.
CDPH will continue to monitor the situation and will advise Californians of any new information.”
