USDA: Offspring of mad cow did not have disease

Investigators looking into California's first case of mad cow disease say they have tracked down at least one of her offspring in another state. Since there is no live test for the disease also known as bovine spongiform encephalopathy, it was euthanized and brain samples were sent to the national laboratory. The test was negative, officials said Wednesday. The USDA announced April 24 that the nation's fourth case of mad cow disease was discovered in the 10-year-old cow. It had been euthanized at a Tulare County dairy a week earlier and sent to the Baker Commodities rendering plant near the Central California town of Hanford, where random testing happened to be taking place that day. That dairy and another associated with it are under quarantine, which is standard procedure. The USDA has declined to name the dairies or the state where the offspring was found. (more) May 3, 2012 AP
