Iowa lab’s business picks up in testing for CWD

October 9, 2002 By admin

The federal lab in Ames where most of the nation’s testing is done on ailments like “Mad Cow” Disease and Chronic Wasting Disease in deer is seeing a significant increase in the number of tests it’s performing. Dr. Mark Hall is head of pathology at the National Veterinary Services Laboratory. He says two years ago, about 23-hundred “Mad Cow” Disease tests were performed. Last year, it was over 20-thousand. With scrapie in sheep, the numbers over two years went from about 400 to 13-thousand. Dr. Hall says the testing numbers are also bounding for C-W-D in deer and elk.Last year, about three thousand C-W-D tests were done at the Ames lab. This year, it’s up to 11-thousand-100 tests. Hall speculates on the reason behind the huge rises in the workload.He says there’s a lot more awareness, especially with the “Mad Cow” Disease scares overseas, the U-S has increased its surveillance, and he expects the numbers to keep rising.Hall says C-W-D numbers are bounding. He expects next year’s testing numbers to go up significantly, from 11-thousand this year to perhaps 200- or-300-thousand next year. He says each test for C-W-D is time-consuming, as a brain sample from a deer is sent in. He says they take the sample, about the size of a nickel, and have to cut it to fit onto a slide and then put on reagents that indicate if the disease is present.Two other national labs do testing as well. They’re located in Colorado and Wyoming. NO cases of C-W-D have been found in Iowa but infected deer or elk have been isolated in Minnesota, Wisconsin and Nebraska.
