Deadly version of H5N1 bird flu spills over into Nevada dairy cattle

LA Times  

A version of the H5N1 bird flu virus that killed a person in Louisiana and severely sickened a teenager in Canada has now been detected in dairy herds in Nevada. Finding D1.1 in dairy cows caught investigators off-guard, but it is just the latest surprise as the H5N1 bird flu continues to flummox researchers and public health officials. Anja Raudabaugh, CEO of Western United Dairies — a California dairy trade group — said the discovery was “extraordinary” and should exacerbate industry concern about the virus, which she described as already being “very high.” She hopes it will compel federal officials to work on a bovine vaccine “ASAP” to stop or slow the spread of the disease between cows. But, she added, the discovery of D1.1 in dairy cows “clearly means that other bird viruses can get into cows.” The virus was discovered as a result of the USDA’s National Milk Testing Program, which requires testing of milk in 38 states, including Nevada, where the herds infected with the D1.1 version were found. “We may have to hope that Canada does the research because our federal researchers appear to be temporarily paralyzed by the political process.” Nevertheless, he urged health officials to begin testing livestock — not just dairy cows — in places with densely situated agricultural operations, such as in Ohio, where since Jan. 1, H5N1 has been found in 40 commercial poultry farms in a two-county area.
