U.S. egg farmers face challenges in controlling severe bird flu outbreak

U.S. egg farmers are struggling to control a severe bird flu outbreak, with millions of birds culled and significant financial and emotional tolls reported. Previous containment strategies, like culling infected flocks, are proving less effective this time. The outbreak has led to increased human cases, including the first U.S. death linked to the virus. Experts are concerned about the virus spreading to mammals and the potential risks to human health, prompting calls for new approaches, including vaccination. Vaccination is a contentious topic, as it could impact poultry exports and trade. While some experts advocate for its use to control the outbreak, logistical challenges and trade implications remain significant barriers to implementation.
