QUEEN ANNE’S COUNTY, MD — Maryland health officials on Tuesday said a second case of bird flu has been detected in a commercial poultry farm in Queen Anne’s County, according to a news release.

The case of highly pathogenic H5N1 avian influenza marks the second in less than a week, according to the Maryland Department of Agriculture. The previous case was discovered at a poultry operation in Caroline County, officials said Friday.

The newest case brings the number of affected poultry operations in the Delmarva region to four. Last month, two cases were confirmed in Kent County, Delaware.

Confirmation of the Queen Anne’s County case is pending testing by the U.S. Department of Agriculture’s National Veterinary Services Laboratory. Meanwhile, state officials have since quarantined the affected facilities and birds on the properties were being depopulated to prevent the spread of the disease.

Birds from affected flocks will not enter the food system, officials said.

Avian influenza — also known as bird flu — is a highly contagious airborne respiratory virus that spreads easily among birds through nasal and eye secretions, as well as manure. The virus can be spread in various ways from flock to flock, including by wild birds, contact with infected poultry, equipment, and the clothing and shoes of caretakers.

The virus affects poultry, like chickens, ducks, and turkeys, along with some wild bird species such as ducks, geese, shorebirds, and raptors.

According to the Department of Health, the risk of transmission between birds and the general public is low; however, those who work directly with poultry or dairy farms may be more at risk.
