Annapolis, MD – The Maryland Department of Agriculture announced on April 4, 2026, the release of a control area in Cecil County following a case of highly pathogenic avian influenza (HPAI). This decision marks a significant step in managing the ongoing surveillance efforts against the virus that has affected both domestic poultry and wild bird populations in the state.
The release applies to all farms in the former control area, except the previously infected premise, which remains under quarantine. Farms outside other active control areas are now free from movement and placement restrictions, as well as the need for enhanced surveillance testing specific to the area.
According to the department, routine HPAI surveillance will continue across the entire state. Producers who introduced birds before the control area was lifted are still obligated to undergo biosecurity audits if not already completed.
To qualify for the release of a control area, several stringent conditions must be fulfilled. These include the depopulation of the infected flock and the proper capping of compost piles. Initial virus elimination procedures on the infected premises must also be finalized. Additionally, required surveillance testing for both commercial and backyard flocks needs to be conducted, with ongoing routine checks persisting statewide.
Even post-release, farms that skipped biosecurity audits and placed chicks prior to the closure must still comply with these requirements.
HPAI, commonly known as bird flu, is a highly contagious airborne respiratory virus. It spreads rapidly among birds via nasal and eye secretions as well as manure. The virus transmits between flocks—including wild bird flocks—through direct contact with infected poultry, shared equipment, or contaminated clothing and footwear of caretakers.
This pathogen impacts a variety of poultry species, including chickens, ducks, and turkeys. In the wild, it affects birds such as ducks, geese, shorebirds, and raptors, posing risks to Maryland’s diverse avian wildlife.
The Maryland Department of Agriculture emphasizes vigilance among poultry owners. Commercial producers are advised to immediately notify their contracting company upon observing disease signs. Backyard flock owners should refrain from transporting dead or sick birds to labs or off-site locations. Instead, they are urged to report unusual mortality or illness spikes to the MDA Animal Health Program at 410-841-5810.
This latest development in Cecil County underscores the state’s proactive approach to containing HPAI outbreaks. Since the detection of the virus in wild birds became more common in Maryland, authorities have implemented robust monitoring and response strategies to protect both agricultural interests and natural ecosystems.
The release of the control area demonstrates that containment measures are effective when protocols are followed diligently. However, the persistence of the virus in wild bird populations highlights the need for continued awareness and preventive actions among all stakeholders.
For more context on HPAI’s impact, the department notes that while the virus primarily affects birds, poultry products remain safe for consumption when handled properly, as confirmed by federal guidelines.
In light of these events, Maryland’s agricultural community is reminded of the importance of biosecurity practices to prevent further spread. This includes limiting access to poultry areas, disinfecting equipment, and monitoring for symptoms such as respiratory distress, reduced egg production, or sudden deaths.
As spring migration approaches, wildlife enthusiasts and hunters are also encouraged to report any unusual bird mortality to relevant authorities, aiding in early detection efforts.
The Maryland Department of Agriculture continues to provide resources and support to mitigate the risks associated with HPAI, ensuring the health of both farmed and wild bird populations. For more information, visit Maryland Department of Agriculture.
