A case of highly pathogenic H5N1 avian influenza (HPAI) has been detected in Caroline County, Maryland, according to the state’s laboratory testing. The affected premises have been quarantined, and birds on the properties are being depopulated to prevent disease spread.
This marks the first reported case of HPAI at a commercial poultry operation in Maryland since 2023. The U.S. Department of Agriculture’s National Veterinary Services Laboratory is confirming the results, with final confirmation expected soon.
Maryland Secretary of Agriculture Kevin Atticks emphasized that H5N1 does not affect poultry meat or egg products, which remain safe to consume. However, he urged commercial growers and backyard flock owners to be vigilant for signs of HPAI and follow biosecurity measures to prevent transmission.
Avian influenza is a contagious airborne respiratory virus that can spread through contact with infected birds, equipment, and human hands. The risk of transmission between birds and the general public is low, but individuals working directly with poultry or dairy farms may be more at risk.
To mitigate risks, the Maryland Department of Agriculture recommends common-sense biosecurity steps, including:
– Reporting suspected sick birds to 410-841-5810
– Clean and disinfect transportation equipment
– Remove loose feed
– Keep visitors to a minimum
– Wash hands before and after contact with live poultry
– Change clothes before entering poultry areas
The public can visit the Maryland Department of Agriculture website for more information on avian influenza and guidance from the U.S. Centers for Disease Control and Prevention.
