Following the detection of the H5N1 virus in a dairy farm employee in Texas, Zhang Wenqing of the WHO has highlighted the critical need for consuming only pasteurized dairy products. This case has led to a collaborative reassessment by the WHO, the World Organization for Animal Health, and the Food and Agriculture Organization regarding the virus's transmission routes and its potential evolution. Notably, the virus, which was previously known for its high lethality and bird-to-human transmission, has demonstrated new patterns of infection, including mammal-to-mammal spread. This shift, along with an uptick in bird and mammal infections since 2020 and the virus's presence in cow and goat milk, has escalated concerns about a possible pandemic, emphasizing the importance of enhanced safety measures in agricultural practices.
