Among 193 ill persons with available information, 49 (25 percent) have been hospitalized. Sixty percent of ill persons are children 10 years of age or younger. Epidemiologic, laboratory, and traceback findings have linked this outbreak of human Salmonella Typhimurium infections to contact with chicks, ducklings, and other live baby poultry purchased from multiple feed stores and sourced from multiple mail-order hatcheries. Continuing traceback investigations to determine the ultimate source of Salmonella Typhimurium infected live poultry linked to this outbreak have been difficult because of the complicated distribution network for these birds.
