The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) today confirmed more H5N1 avian flu detections in poultry from three states, including on a second commercial broiler farm in Delaware’s Kent County.
Also, officials confirmed an outbreak at a backyard farm in Michigan’s Oakland County that has 100 birds, an event first announced by Michigan’s agriculture department yesterday.
APHIS also confirmed a detection in Missouri, which involves poultry at a backyard farm housing 20 birds in Perry County.
Meanwhile, APHIS confirmed one more H5N1 detection in dairy cattle, which involves another herd in California. The latest addition lifts the national total to 924 in 16 states and puts California’s total at 707 since the end of August 2024.
In other federal developments, the Centers for Disease Control and Prevention (CDC) revised its interim guidance for employers to reduce exposure to influenza A (including H5N1) in people working with animals. Changes were made to improve the readability and organization of the guidance, which now covers workers in a wider range of settings, including zoos and sanctuaries.
Preliminary positive in Maryland poultry
Separately, the Maryland Department of Agriculture (MDA) today announced that preliminary tests have identified avian flu at a broiler operation in Caroline County, which is located on the state’s eastern border with Delaware.
MDA officials said the outbreak is the first in Maryland’s commercial poultry since 2023 and the third in the Delmarva region, a recently affected part of Delaware.
