The worst-ever outbreak of highly pathogenic avian influenza continued, with the virus affecting flocks in the U.S. and abroad.
On Feb. 21, the USDA's Animal and Plant Health Inspection Service announced an HPAI outbreak in a commercial broiler production flock in Lancaster County, Pa. The USDA stated that 97,700 birds were affected, and the outbreak is still considered active.
That is the third commercial broiler outbreak so far in 2023. On Jan. 20, a detection in Weakley County, Tenn. affected 267,800 birds, and a Feb. 7 outbreak in Leake County, Miss. affected 89,800 birds.
Like the U.S., Canada is also grappling with historic HPAI outbreaks. According to the Canadian Food Inspection Agency, approximately 7.2 million domestic birds in Canada have been affected in the last year, with 3.7 million cullings in British Columbia alone. The Globe and Mail notes that more than $82 million has been paid, to date, as compensation for cullings.
South America, Caribbean cases
HPAI was recently declared "endemic" by world health experts, and the virus has continued its spread to other countries.
In the last week, both Argentina and Uruguay confirmed their first cases among wild birds, according to Poultry World. Currently, Brazil, Guyana, and Suriname are the only South American countries without detections. Argentina’s secretary of Agriculture, Livestock and Fisheries, Juan José Bahillo, blamed migratory birds for the country's detection; the secretary called an emergency meeting to address matters.
Additionally, WATT cited WOAH reports that three birds at Cuba's Jardín Zoológico de La Habana zoo in Havana died from HPAI. The detection resulted in the culling of 82 birds in the zoo's area.
