dairy cattle

Highly pathogenic avian influenza (HPAI), or “bird flu,” is on the move in dairy herds across the United States, and while scientists seemed baffled by the means of the H5N1 virus’ initial leap from poultry to a herd of Texas dairy cattle in March, poultry-industry insider William Wymore, of Owensville, believes its transmission can be easily explained. The storage and land-application of poultry and meat-processing sludge is facilitating the spread of bird flu, he alleges.
