APHIS offers the Defend the Flock education program to provide the tools and resources you need to make sure that you are doing everything possible to keep your birds healthy and reduce the risk that an infectious disease will spread from your property to other flocks. Biosecurity is the key to keeping our Nation’s poultry healthy!

USDA. Animal and Plant Health Inspection Service.

The Defend the Flock program provides information and resources from USDA and other experts for keeping poultry healthy. It includes practical tips from growers like you, veterinarians, state agencies, scientists, and industry professionals for practicing biosecurity every day. Biosecurity is a team effort. We have to work together to defend our nation’s flocks. Resources include information needed to practice good biosecurity is available here -- checklists, resource guides, videos, and other tools.

Avian influenza, or "bird flu," is a contagious viral disease of domestic and wild birds. It's a major threat to the poultry industry, animal health, trade, and the economy worldwide. Provides information how to report signs of animal disease, current status and information for controlling avian influenza.

Understanding how wild birds facilitate the maintenance, reassortment, and dispersal of influenza A viruses (IAV) is key to forecasting global disease spread. The current highly pathogenic avian influenza outbreak in North America highlights the question of how viruses are transported between continents. Recent NWHC research sheds light on this question and the potential role Iceland may play.

The first 2021/2022 detection of Eurasian strain (EA) highly pathogenic avian influenza (HPAI) H5N1 in North America occurred in December 2021 in Newfoundland and Labrador, Canada. Subsequently, HPAI EA H5 and EA H5N1 viruses have been confirmed in wild birds, backyard flocks, and commercial poultry facilities in both Canada and the United States. This HPAI distribution map will be updated weekly or as frequently as documented changes in distribution are available.

For the first time, scientists have tracked the movement of a wild bird known to be infected with highly pathogenic avian influenza in North America. The new research, led by the U.S. Geological Survey, can help improve estimates of when and where the virus could spread in the environment and to other birds.

ARS vaccine helps to defend rare bird from avian influenza. Scientists with the Agricultural Research Service (ARS) recently joined other federal agencies to take emergency action to protect one of America’s endangered species, the California condor.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has developed a publicly available dashboard that displays the results from nation-wide avian influenza virus (AIV) monitoring in wild bird populations. Data presented in the dashboard can identify increased AIV risk and can provide information to poultry producers, wildlife managers, and members of the public on AIV activity in their area.

The U.S. Department of Agriculture today announced it is taking several additional actions to ensure the health and viability of the nation’s livestock and poultry. In the two months since the initial detection of H5N1 in dairy cattle, USDA has worked quickly and in concert with its federal and state partners to better understand the virus and contain the disease and remains committed to seeking additional ways to collect the data needed to better understand and mitigate the risk created by this outbreak.

USDA announced the agency is planning to enhance testing and monitoring for H5N1, building on measures taken by USDA since the beginning of the avian influenza outbreak. In partnership with state veterinarians, USDA will implement a tiered strategy to collect milk samples to better assess where H5N1 is present, with the goal to better inform biosecurity and containment measures, as well as to inform state-led efforts to reduce risk to farm workers who may be in contact with animals infected with H5N1. Since this disease was first detected in dairy cattle in March 2024, the USDA and state and federal partners have taken several steps to better understand the virus and work to eliminate it from dairy herds.

The U.S. Department of Agriculture is providing $502 million under the Animal Health Protection Act to the Animal and Plant Health Inspection Service (APHIS) to prepare for potential additional detections of highly pathogenic avian influenza (HPAI) in the United States.

USDA continues to successfully combat HPAI in the United States. In May 2022, there were a total of 18 commercial poultry HPAI detections. In May 2023, there were 0 commercial poultry detections, a decrease of 100% from the previous year. Additionally, there has not been a case of HPAI in commercial poultry since April 19, 2023 or in backyard poultry since May 18, 2023.
