Eighteen lambs were fed milk from scrapie-affected ewes. Three of these lambs were culled and two were found to have PrPd in intestinal tissues. The prion protein was also detected in lymphoid tissue of the gut of the surviving lambs and in some control lambs, mixed with the scrapie milk recipients after weaning.
According to Katherine O'Rourke, Ph.D., of the U.S. Department of Agriculture's Agricultural Research Service, "These results help confirm earlier research demonstrating that abnormal prions can be found in the udders of some scrapie-infected sheep with mastitis."
There are no known human health implications from scrapie.
