Maryland - Avian influenza in wild birds 2025-2026

Laboratory testing has provided preliminary confirmation of Highly Pathogenic H5 Avian Influenza (HPAI) in seven dead snow geese found in Worcester and Dorchester counties.

Avian influenza is an airborne respiratory virus that spreads quickly among birds, although risk to human health is considered low.

Anyone who fills birdfeeders for the winter should feel free to do so, as songbirds also carry very low risk of getting or spreading the virus.

Poultry are at risk and owners should practice biosecurity measures as provided by the Maryland Department of Agriculture.

Hunting wild birds remains safe but some guidelines should be followed: Never harvest or handle wild birds that are obviously sick or found dead, wash your hands with soap and water or hand sanitizer immediately after handling game; use disposable gloves when handling game and double-bag offal and feathers; and use dedicated tools for cleaning game, whether in the field or at home, that are not used around poultry or pet birds.

Poultry Farmers Urged to Practice Enhanced Biosecurity

January 9, 2025


High Path Avian Influenza Identified in Maryland Wildlife

ANNAPOLIS, MD (January 9, 2025) – The Maryland Department of Agriculture is urging all poultry farmers to remain vigilant and practice enhanced biosecurity on their farms after U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed findings of highly pathogenic avian influenza (HPAI) in snow geese in Dorchester and Worcester Counties on Maryland’s Eastern Shore. These wild bird detections come in the midst of HPAI cases in two commercial poultry operations in Kent County, DE.

“The detections in our region should be very concerning to commercial and backyard flock owners,” said Secretary Kevin Atticks. “MDA is monitoring the situation very closely and will continue to provide updates as they become available.”

Migratory waterfowl moving through Maryland presents a heightened risk for HPAI, a devastating disease for poultry operations. HPAI is caused by an influenza type A virus, which can infect poultry (chickens, turkeys, pheasants, quails, domestic ducks, geese, and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds.

Commercial and backyard flock owners are urged to follow these guidelines to maintain a sanitary, biosecure premise:
  • Restrict access to poultry by posting “Restricted Access” signage, securing the area with a gate, or both.
  • Take steps to ensure that contaminated materials on the ground are not transported into the poultry growing house or area.
  • Provide the following items to anyone entering or leaving any area where poultry are kept:
    • Footbaths and foot mats with disinfectant;
    • Boot washing and disinfectant station;
    • Footwear change or foot covers.
  • Cover and secure feed to prevent wild birds, rodents or other animals from accessing it.
  • Cover and properly contain carcasses, used litter, or other disease-containing organic materials to prevent wild birds, rodents or other animals from accessing them and to keep them from being blown around by wind.
  • Allow MDA to enter the premises during normal working hours to inspect your biosecurity and sanitation practices.
  • Report any unusual bird deaths or sudden increases in very sick birds to the MDA Animal Health Program at 410-841-5810 or after-hours to 410-841-5971. Also contact the USDA at 866-536-7593.

ALERT

The Charles County Department of Health has received a report of dead wild birds (vultures) in the county (La Plata area). The birds have been collected and tested for highly pathogenic avian influenza (HPAI). Preliminary results were received today (9/12/2025) and are presumptively positive for avian influenza. Once we receive confirmed results, we will post the findings. The risk to the public is LOW; however, you should not handle dead or sick birds.

Avian influenza is a highly contagious airborne respiratory virus that spreads quickly among birds through nasal and eye secretions and droppings. The virus can be spread from flock to flock, including flocks of wild birds, through contact with infected poultry, equipment, and the clothing and shoes of caretakers. This virus affects poultry, like chickens, ducks, and turkeys, and some wild bird species, such as ducks, geese, shorebirds, and raptors (i.e. vultures).

IF YOU HAVE SICK POULTRY OR EXPERIENCE INCREASED MORTALITY

• Commercial poultry producers should follow the protocol of notifying the company they grow for when they notice signs of disease.
• Maryland backyard flock owners who notice any of the signs of HPAI in their flock should email the email the Maryland Department of Agriculture Animal Health team at md.birdflu@maryland.gov or animalhealth.mda@maryland.gov or by calling 410-841-5810. Please be prepared to provide your contact information, size of flock, location, and concerns. Do not take dead or sick birds to a lab to be tested to move them off-site.

As a reminder, backyard flock owners are required to register their flocks with the Maryland Department of Agriculture to assist in protecting Maryland’s poultry industries from diseases such as HPAI.

Additionally, the Maryland Department of Natural Resources urges waterfowl hunters to take safety precautions to prevent the spread of the virus by washing hands and clothes after handling game and using dedicated clothing, boots, and tools for cleaning game that are not used around domestic poultry or pet birds. Individuals who encounter a dead wild bird should call USDA’s Animal and Plant Health Inspection Service, which is coordinating collection and disposal efforts with the Department of Natural Resources, at 1-877-463-6497.

Discovery of black vulture carcasses force hiking trail closures around Conowingo Dam

By: Ryan Dickstein
Posted 1 hour and 13 minutes ago and last updated 1 hour and 3 minutes ago

DARLINGTON, Md. — Avian flu fears have forced the temporary closure of certain hiking trails surrounding Conowingo Dam.

Constellation, who operates the dam, said black vulture carcasses were recently collected near Fishermen’s Park that tested positive for H5N1 avian influenza..

Avian flu continues to impact Maryland wildlife and poultry farms

Dead black vultures found near Conowingo Dam test positive for avian flu

DARLINGTON, Md. —

An ongoing avian flu outbreak over four years continues to affect Maryland's wildlife and poultry farms, with state and federal agencies working to reduce its spread.

"Conowingo is one with the Black vultures that's sort of been a persistent location," said Josh Homyack, gamebird section leader with the Maryland Department of Natural Resources.

Dead black vultures found near Fisherman's Park at the Conowingo Dam tested positive for avian flu, leading Constellation, the dam's operator, to temporarily close the Wildflower and Mason Dixon hiking trails in May.

"In the past, these (Highly Pathogenic Avian Influenza) epidemics have kind of run their course, you know, and this one will, too. Sometimes, they do it in a year or two. Sometimes, it takes longer than this. Unfortunately, it's just one of the ones it takes longer," Homyack told WBAL-TV 11 News.
