The USDA has confirmed that a case of mad cow disease was found in a
California dairy cow. It is the fourth case of mad cow, or bovine spongiform
encephalopathy (BSE), in recent years.
USDA Chief Veterinary Officer John Clifford said Tuesday afternoon that the
cow did not enter the human food chain and that all U.S. meat and dairy
supplies are safe. Further mitigating the risk to the public, milk does not
transmit BSE.
According to the USDA, the animal's carcass is being held under state
authority at a California rendering facility and will be destroyed. "It was
never presented for slaughter for human consumption, so at no time presented
a risk to the food supply or human health," Clifford said.
The USDA said that they have begun notifying authorities at the World
Organization for Animal Health (OIE) as well as U.S. trading partners. The
USDA does not expect the detection of mad cow to affect U.S. beef exports,
however.
Read the full statement from the USDA on the mad cow discovery:
"As part of our targeted surveillance system, the U.S. Department of
Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) has
confirmed the nation's fourth case of bovine spongiform encephalopathy (BSE)
in a dairy cow from central California. The carcass of the animal is being
held under State authority at a rendering facility in California and will be
destroyed. It was never presented for slaughter for human consumption, so
at no time presented a risk to the food supply or human health. Additionally
, milk does not transmit BSE.
"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.
"Samples from the animal in question were tested at USDA's National
Veterinary Services Laboratories in Ames, Iowa. Confirmatory results using
immunohistochemistry and western blot tests confirmed the animal was
positive for atypical BSE, a very rare form of the disease not generally
associated with an animal consuming infected feed.
"We are sharing our laboratory results with international animal health
reference laboratories in Canada and England, which have official World
Animal Health (OIE) reference labs. These labs have extensive experience
diagnosing atypical BSE and will review our confirmation of this form of 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.
"USDA remains confident in the health of the national herd and the
safety of beef and dairy products. As the epidemiological investigation
progresses, USDA will continue to communicate findings in a timely and
transparent manner." | g*q
