The Centers for Disease Control and Prevention is currently investigating a multi-state outbreak of Salmonella infections linked to backyard poultry, including chickens and ducks.
As of April 29, 2026, a total of 34 cases have been reported across 13 U.S. states, with 13 hospitalizations. However, health officials warn that the actual number of cases may be significantly higher, as many infected individuals recover without medical care and are not tested.
The affected states include:
Florida, Illinois, Indiana, Kentucky, Maryland, Maine, Michigan, Mississippi, New Hampshire, Ohio, Tennessee, Wisconsin, and West Virginia.
Epidemiological investigations indicate that 79% of infected individuals had contact with backyard poultry. Additionally, several individuals reported acquiring poultry animals after January 1, 2026.
Despite ongoing investigations, authorities have not identified a single supplier responsible for the outbreak, suggesting a broader risk associated with backyard poultry handling.
Salmonella bacteria can be present in apparently healthy birds and may spread through:
Infection can occur when individuals touch contaminated surfaces and then touch their mouth or food.
The CDC advises individuals who own or interact with backyard poultry to follow strict hygiene practices:
Symptoms typically appear 6 hours to 6 days after exposure and may include:
Most healthy individuals recover within a week without treatment. However, severe illness may occur in young children, elderly individuals, and those with weakened immune systems.
Individuals experiencing symptoms after contact with backyard poultry are advised to seek medical attention promptly. Confirmed cases should also be reported to local or state health authorities to support outbreak tracking and response efforts.
