Government Orders Killing of 129 Cows in Herd Linked to Infected Holstein

Cattlemen, politicians and residents of Mabton, Washington, plan to rally this afternoon in support of the state's cattle industry.

Meanwhile, today agriculture officials plan to kill 129 more animals linked to the nation's first case of mad cow disease.

The cows come from the Mabton dairy farm that was the last home to the infected Holstein.

Investigators say nine of the cows came from the same Canadian farm where the sick Holstein was born. The USDA's chief veterinarian says the other 120 possibly came from that same farm.

The killed cows will be tested for mad cow disease. If the tests are negative, they'll be buried in a landfill. But if some test positive, the carcasses will be incinerated or destroyed with acid.
