A better test for mad cow

Taking tissue from slaughtered animals is now the only method, and its costs can be high When the nation's first case of mad cow disease was discovered on a Washington farm, it took the slaughter of more than 700 healthy cattle to prove the disease had not spread. That's because there's no test for mad cow that can be done on live animals, and there may not be one for some time.
"I don't know how far away we are," said Don Knowles, who runs a U.S. Department of Agriculture laboratory in Pullman that is working with Washington State University scientists to develop such a test.
