Bird flu is ‘everywhere’ on dairy farms
A preprint study suggests that the H5N1 avian influenza virus is widespread on dairy farms, including in wastewater, in the air in milking parlours and in the exhaled breath of cows — indicating how it is spreading so readily in those environments. “It is everywhere,” says microbiologist and immunologist Seema Lakdawala, who co-authored the study, which has not yet been peer-reviewed. “We need to be expanding biosafety measures, biosecurity measures and trying to control where the virus is.”
