A new strain of bird flu, H5N9, has been confirmed at a duck farm in California, marking the first reported outbreak of this rare virus in the United States. The discovery follows a troubling increase in bird flu cases in the Bay Area, including the H5N1 strain. Health officials are investigating the situation, which has led to the killing of around 119,000 ducks to control the outbreak. Concerns are growing over the implications of this new strain, as it raises questions regarding poultry health and food safety. Experts advise vigilance regarding the symptoms of bird flu and discuss the safety of consuming chicken and eggs during this outbreak.
