The USDA has confirmed a case of mad cow disease in a dairy cow near Fresno. This is just the fourth case of mad cow disease found in the U.S. since the disease first appeared in the country in 2003. Agriculture officials say meat-eaters are not at risk because it's an atypical case -- the infected cow was not intended for the food supply and the disease cannot be transmitted by milk. But consumer advocates say there are many questions yet to be answered.
