Usda probes 3rd case of mad cow { July 27 2005 } Original Source Link: (May no longer be active)    http://today.reuters.com/business/newsarticle.aspx?type=tnBusinessNews&storyID=nN27421013&imageid=&cap= http://today.reuters.com/business/newsarticle.aspx?type=tnBusinessNews&storyID=nN27421013&imageid=&cap= UPDATE 3-USDA probes possible 3rd case of mad cow disease Wednesday 27 July 2005, 5:56pm EST WASHINGTON, July 27 (Reuters) - A cow suspected of having mad cow disease will be retested in British and U.S. laboratories for confirmation of what may be America's third case, the U.S. Agriculture Department said on Wednesday. Final test results are expected early next week. The U.S. cattle industry said existing safeguards prevented the suspect cow from entering the human food supply, but consumer groups said more measures were needed to protect Americans. USDA Chief Veterinarian John Clifford said the suspect animal, which was destroyed after having trouble giving birth in April, produced an inconclusive result in an initial round of testing for the brain-wasting disease. "USDA is conducting further testing at the National Veterinary Services Laboratories in Ames, Iowa, in consultation with experts from the international reference laboratory in Weybridge, England," he told reporters. "We are also sending samples from this animal to the Weybridge laboratory for further testing." The first U.S. case, reported in 2003, prompted major beef trading partners like Japan, South Korea and Taiwan to halt billions of dollars worth of U.S. beef imports. The latest incidents come as Bush administration officials had started to make optimistic comments about persuading those countries to resume buying U.S. beef. Clifford said he did not think the new probe would affect trade negotiations. The USDA said the cow was born in the United States at least 12 years ago, but refused to identify where it lived. The USDA banned the use of cattle remains in cattle feed in 1997 to stop what is believed to be the main way bovine are infected. America's second case of mad cow disease -- its first in a native animal -- was confirmed last month. That animal, a 12-year-old Texas cow, tested positive for the brain wasting disease after initially returning inconclusive results. VET FORGOT TO SEND SAMPLE The latest case also involves confusion and possible missteps over test procedures. A local veterinarian who submitted the cow's brain sample to the USDA first treated it with a preservative, making it impossible to conduct a sophisticated test known as the Western blot, Clifford said. USDA scientists can still conduct an immunohistochemistry (IHC) test, but they cannot use the Western blot test for a comparison. In addition, the veterinarian obtained the brain sample in April but did not send it to the USDA until a few days ago, Clifford said, because he "simply forgot to send it in." The sample was also frozen, counter to USDA guidelines. The first U.S. case of bovine spongiform encephalopathy (BSE) or mad cow disease was found in December 2003, in a Washington state dairy cow imported from Canada. It prompted the USDA to adopt new safeguards including more testing of cattle for the disease and a ban on using crippled or downer cattle in human food. CONSUMER GROUPS WANT MORE TESTING Consumer advocates said the USDA must continue its enhanced surveillance program and strenghten safeguards. More than 419,000 cattle were tested in the past 13 months in a stepped-up testing program designed to run up to 18 months. "This is possibly the third case, indicating now that we really should keep our testing program, if not expand it," said Jean Halloran, food policy director for Consumers Union. Halloran also said the Food and Drug Administration must close its loopholes and ban the use of cattle blood, chicken litter and restaurant scraps for animal feed. U.S. Agriculture Secretary Mike Johanns told Reuters on Wednesday it was not yet time to decide whether the stepped-up program should be maintained. "We're not there today," Johanns said in an interview on Capitol Hill. The beef industry said the U.S. food supply is safe. "It is important to remember that the U.S. government and the beef industry have put science-based precautions in place over the past 15 years to ensure our beef remains safe from BSE," said Terry Stokes, chief executive of the National Cattlemen's Beef Association. The USDA also recently won a court appeal to start imports of live young Canadian cattle for the first time in two years, arguing against protests from ranchers and consumer groups that Canada's safeguards against the disease were adequate.
