Ill people reported purchasing live baby poultry from several suppliers, including feed supply stores, Internet sites, hatcheries, and friends in multiple states. Ill people reported purchasing live poultry to produce eggs, learn about agriculture, have as a hobby, enjoy for fun, keep as pets, or to give as Easter gifts. Some of the places ill people reported contact with live poultry include their home, someone else’s home, work, or school settings.
Public health officials collected samples from live poultry and the environments where the poultry live and roam from the homes of ill people in several states. Laboratory testing isolated four of the outbreak strains of Salmonella.
