Avian Flu Confirmed in Commercial, Wild, Domestic Birds Across US, Brazil, Canada, Philippines Cleared

Multiple countries in the Americas are currently managing outbreaks of highly pathogenic avian influenza (HPAI) affecting commercial and non-commercial poultry. The Philippines has successfully contained its recent H5N9 avian flu outbreak with no new active cases reported following rigorous control measures. In the United States, a commercial poultry farm in Maricopa County, Arizona, has tested positive for avian flu, prompting quarantine and biosecurity actions, although there is low risk to the public. Brazil, the world's largest chicken exporter, is addressing fresh bird flu cases in wild birds and investigating a potential new commercial farm outbreak in Rio Grande do Sul, following earlier cases that triggered trade restrictions. In Canada, the first detection of HPAI in domestic birds in Prince Edward Island has been confirmed at a non-commercial poultry site, with authorities emphasizing biosecurity and vigilance during migratory seasons. These outbreaks underscore the ongoing threat of HPAI to poultry industries and the importance of surveillance and containment efforts internationally.
