Multistate outbreaks of human salmonella infections linked to live poultry in backyard flocks

Must read

WASHINGTON — USDA has reported that as of June 29, 2015, 181 people infected with the outbreak strains of salmonella have been reported from 40 states with 33 ill people being hospitalized. No deaths have been reported.

The Centers for Disease Control & Prevention, public health veterinary, and agriculture officials in many states and USDA’s Animal & Plant Health Inspection Service (USDA-APHIS) are investigating four multistate outbreaks of human salmonella infections linked to contact with live poultry.

Epidemiologic, laboratory, and traceback findings have linked these four outbreaks of human salmonella infections to contact with chicks, ducklings and other live poultry from multiple hatcheries. Eighty-two (86 percent) of the 95 ill people who were interviewed reported contact with live poultry in the week before their illness began.

CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory conducted antibiotic resistance testing on Salmonella isolates collected from seven ill people infected with one of the outbreak strains. All seven isolates were susceptible to all antibiotics tested on the NARMS panel.

Antibiotic resistance testing continues on additional isolates collected from ill people infected with the outbreak strains.

APHIS states that backyard flock owners should take steps to protect themselves and their families:

  • Always wash hands thoroughly with soap and water right after touching live poultry or anything in the area where the birds live and roam.
  • Do not let live poultry inside the house.
  • Learn about additional recommendations to prevent salmonella infections from live poultry. These recommendations are important and apply to all live poultry, regardless of the age of the birds or where they were purchased.
  • Mail-order hatcheries, agricultural feed stores and others that sell or display chicks, ducklings and other live poultry should provide health-related information to owners and potential purchasers of these birds prior to the point of purchase. This should include information about the risk of acquiring a salmonella infection from contact with live poultry. ?Read the advice to mail-order hatcheries and feed stores and others that sell or display live poultry.
  • In the four outbreaks the number of ill people identified in each state is as follows: Alabama (17), Arizona (3), Arkansas (4), California (3), Colorado (2), Delaware (2), Georgia (4), Indiana (3), Iowa (1), Kentucky (4), Louisiana (2), Maine (2), Maryland (4), Massachusetts (1), Michigan (3), Minnesota (6), Mississippi (13), Missouri (1), Montana (3), Nevada (2), New Hampshire (1), New Jersey (3), New Mexico (2), New York (6), North Carolina (3), Ohio (15), Oklahoma (1), Oregon (5), Pennsylvania (12), South Carolina (10), South Dakota (2), Tennessee (6), Texas (5), Utah (4), Vermont (2), Virginia (11), Washington (6), West Virginia (2), Wisconsin (1), and Wyoming (4).
