Nationwide Salmonella outbreak linked to handling live animals
The Centers for Disease Control and Prevention is collaborating with public health, veterinary, and agriculture officials in many states, as well as the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS), to investigate seven separate multistate outbreaks of human Salmonella infections. Results from these investigations showed that contact with live poultry in backyard flocks was the likely source of these outbreaks.
In seven separate multistate outbreaks, a total of 324 people infected with the outbreak strains of Salmonella were reported from 35 states. Among people who reported the date they became ill, illnesses started on dates ranging from January 4, 2016 to May 11, 2016.
In interviews, ill people answered questions about contact with animals and other exposures in the week before becoming ill; 217 (91%) of the 238 people interviewed reported contact with live poultry in the week before their illness. Ill people reported purchasing live baby poultry from several different suppliers, including feed supply stores, Co-Ops, 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 at their home, someone else’s home, work, or school settings.
CDC's NARMS laboratory conducted antibiotic-resistance testing on clinical isolates collected from three people infected with one of the seven outbreak strains. All three isolates were susceptible to all antibiotics tested. CDC's NARMS laboratory continues to conduct antibiotic-resistance testing on additional clinical isolates collected from ill persons infected with one of the outbreak strains.
