Possible new case of mad cow disease found in the United States

WASHINGTON - A second case of mad cow disease may have turned up in the United States but the suspect meat has not entered the food chain, Agriculture Department officials said Thursday.

The officials released few details and refused to say where the possibly diseased animal was found. They said it would be four to seven days before more could be confirmed, a delay that livestock industry representatives said would cause turmoil in the beef market.

Mad cow disease, or bovine spongiform encephalopathy, attacks an animal¹s nervous system. People who eat food contaminated with BSE can contract a rare disease that is nearly always fatal, variant Creutzfeldt-Jakob disease.

The possible case comes 11 months after the United States had its first case of mad cow disease. Japan and other countries are still maintaining bans against U.S. beef as the result of the earlier case.

Suspicions about another case of the disease came because of an inconclusive test result, officials said.

³The inconclusive result does not mean we have found another case of BSE in this country,² said Andrea Morgan, associate deputy administrator of the USDA¹s Animal and Plant Health Inspection Service.

She said the inconclusive results ³are a normal component of screening tests, which are designed to be extremely sensitive so they will detect any sample that could possibly be positive.²

³It is important to note that this animal did not enter the food or feed chain,² Morgan said. ³USDA remains confident in the safety of the U.S. beef supply. Our ban on specified risk materials from the human food chain provides the protection to public health, should another case of BSE ever be detected in the United States.²

Morgan said initial efforts had begun to trace back the animal from where it was tested to the farm from which it originated.

Meat industry in limbo
The wait to find out more about this possible new case of BSE has ³put the entire industry really in limbo,² said John McBride, a spokesman for the Livestock Marketing Association, based in Kansas City, Mo.

³With final results not being available for four to seven days, it¹s going to disrupt the livestock market. Buyers are going to be reluctant to buy, sellers are going to be reluctant to put their livestock on the market,² he said. ³The effect on the market could be profound.

Officials at the Cattlemen¹s Beef Promotion and Research Board, which is based in Centennial, Colo., and monitors consumer perceptions and attitudes, had no immediate comment.

Just before the start of the July Fourth weekend, the department had announced two other possible cases of the brain-wasting illness in the United States ‹ but then said follow-up testing had proved negative. Both were subjected to the more definitive testing after initial screenings for infection were inconclusive.

Thousands of animals have been tested under new screening procedures that took effect June 1 to address complaints that too few animals in the United States are tested for the disease. The mad cow screening programs used by the government were developed by Bio-Rad Laboratories of Hercules, Calif., and have been used in Europe for a number of years.

In the only confirmed U.S. case, a Canadian-born Holstein was found to have been infected, but just that one case caused Japan and more than three dozen other countries to refuse U.S. beef. That hurt U.S. export sales and the farm economy.

Bush administration officials are now focused on trying to get those bans lifted and with establishing a national identification system for tracking livestock and poultry from birth through the production chain.

Such a system has worried producers who prefer to keep their records confidential or run a voluntary ID clearinghouse that would provide government officials with limited access. © 2004 The Associated Press.

2. Cattle Prices Tumble; U.S. May Have 2nd Case of Mad Cow Disease Nov. 18 (Bloomberg) -- Cattle prices in Chicago fell the most in four months on concern a preliminary test for mad cow in the U.S. may lead to the country's second confirmed case of the disease. The Department of Agriculture's rapid-screening program found its first inconclusive test for the brain-wasting disease since June. Tissue samples are being tested at an Ames, Iowa, lab to determine whether the animal has bovine spongiform encephalopathy, or BSE. The meat didn't enter the food chain, and test results are expected in four to seven days. ``The market hates uncertainty and this test result increases uncertainty about demand,'' said Bob Wilson, an analyst for HedgersEdge.com in Greenwood Village, Colorado. ``We won't know if this is an overreaction until the test results come back.'' Cattle futures for February delivery fell 2.45 cents, or 2.8 percent, to 86.45 cents a pound at 10:25 a.m. on the Chicago Mercantile Exchange, the biggest percentage decline since June 28, when another inconclusive test was announced.
A futures contract is an agreement to buy or sell a commodity at a specified price and date.
Cattle futures fell 4.1 percent in the past year after the disease was discovered in December and more than 40 nations banned U.S. beef. The latest sample is the third to produce inconclusive results. The two others were later found to be negative. A total of 113,264 tests have been conducted since June 1, the USDA said on its Web Site. Inconclusive tests have raised concern that government efforts to boost exports may be derailed. U.S. beef exports last year were valued at $3.8 billion. A second confirmed case of mad cow may erode consumer demand and sales for companies such as Tyson Foods Inc., the largest U.S. beef processor.
