US authorities have reported the country’s first case of mad cow disease in six years.
The brain disease was detected in a dairy cow in California.
The Department of Agriculture’s head vet said there was no reason for consumers to panic.
“We will complete an investigation of this particular case and there should be no concern as indicated about the safety of our food supply,” said John Clifford, the USDA’s chief veterinary officer.
Mad Cow disease, or Bovine Spongiform Encephalopathy, was first discovered in Britain in 1986.
The first American case was found in 2003.
The brain-wasting condition leads to loss of bodily functions and eventually the infected cow’s death.
