Backyard poultry keeping has grown steadily among gardeners and homesteaders who value fresh eggs and self-sufficiency. This year the Centers for Disease Control and Prevention tracked an unusually large cluster of Salmonella infections linked to those same flocks. The agency has now declared the multistate outbreak over.
Extent of the Illnesses
A total of 1,253 people across 46 states and Puerto Rico became ill with one of seven outbreak strains: Salmonella Altona, Enteritidis, Indiana, Infantis, Kedougou, Mbandaka, or Saintpaul. One in five patients was younger than five years old, though ages ranged from infants to 99 with a median of 36. Roughly one-third of those affected required hospital care, and two deaths were recorded. The CDC sequenced every confirmed human isolate. Hundreds showed resistance to at least one antibiotic, including fosfomycin, nalidixic acid, and tetracycline. These findings underscore that backyard flocks can carry strains capable of complicating treatment when illness occurs.
How the Bacteria Reached Households
Most people or their caregivers reported buying chicks and ducklings from agricultural retail stores. Others obtained birds from acquaintances, hatcheries, or local farms. Investigators traced the same genetic strains found in patients to samples collected from live poultry and shipping boxes in six states. Eight hatcheries were identified as sources of infected birds, though none were publicly named. The first illnesses began in late February. The CDC issued its initial alert in mid-April when only 34 cases had been confirmed. By the time the outbreak was declared over, the total had grown dramatically. Public health officials note that many additional cases likely went undetected because not every sick person seeks testing.
Comparison With Earlier Years
This event ranks as the second-largest backyard-poultry Salmonella outbreak on record. The largest occurred in 2020, when pandemic-related stay-at-home orders coincided with a surge in new flock owners. Annual totals have fluctuated since, yet the pattern of springtime peaks tied to chick purchases has remained consistent. The current episode also stands out for the number of distinct Salmonella serotypes involved and the geographic spread. Even so, the CDC emphasizes that the risk stems from specific handling practices rather than poultry ownership itself.
Practical Steps for Current Flock Owners
Health authorities continue to stress basic hygiene measures that sharply reduce transmission. Wash hands thoroughly after any contact with birds, coops, or equipment. Keep poultry areas separate from food preparation spaces and never allow birds inside the home. Supervise young children closely during interactions and ensure they wash hands immediately afterward. Regular coop cleaning, prompt removal of droppings, and sourcing birds from reputable suppliers further lower exposure. Those who notice signs of illness in their flock should consult a veterinarian and avoid handling sick birds without protection. These steps align with long-standing recommendations that have helped many keepers avoid problems even during active outbreaks.
What Remains Unknown
Investigators have not released the names of the implicated hatcheries, leaving some buyers without a clear way to trace their birds. It is also unclear whether new biosecurity protocols at hatcheries will prevent similar events next spring. For now, the CDC’s declaration signals that the immediate wave of illnesses has subsided, yet the underlying risk factors persist for anyone raising poultry at home. Continued vigilance remains the most reliable safeguard.
