England is culling a second herd of cattle feared to have foot-and-mouth disease. The animals were showing symptoms on an unidentified farm within a restricted zone around the area southwest of London where the first outbreak occurred. Investigators were considering the possibility that a flood in July may have spread the virus.
If floodwater was the source, it would add support to the theory that nearby labs that manufacture vaccines for the disease may have leaked the virus into the water supply. The labs have denied any problems with biological waste disposal. "It's awful, unbelievable," said a farmer. "Just when farming was doing well, suddenly you're knocked down again."
