““The USDA’s “Dairy Management Practices” report indicates that approximately one in seven dairy cows in the United States suffers from clinical mastitis, a painful bacterial infection of the udders that is exacerbated by accelerated milk production. In advanced stages, mastitis can be fatal; it is the second leading cause of death in dairy cows who die prior to slaughter. Mastitis, termed a “production disease,” is one of the most frequent and costly afflictions in intensive dairy production. In fact, mastitis is, and has been, such a common and financially catastrophic ailment that the dairy industry established the National Mastitis Council in 1961 specifically to study and combat this disease.””
