As of July 13, 2018, 212 people infected with the outbreak strains of Salmonella have been reported from 44 states.

  • Illnesses started from February 15, 2018 to June 21, 2018.
  • 34 ill people have been hospitalized, and no deaths have been reported.
  • 26% of ill people are children younger than 5 years.

Epidemiologic, traceback, and laboratory findings link these outbreaks to contact with live poultry, such as chicks and ducklings, which come from multiple hatcheries.

  • In interviews, 100 (72%) of 138 ill people with information available reported contact with chicks or ducklings in the week before their illness started.
  • People reported obtaining chicks and ducklings from several sources, including feed supply stores, websites, hatcheries, and from relatives.

WGS analysis to identify antibiotic resistance was performed for 118 isolates from ill people in this outbreak. Twenty-two isolates from ill people contained genes expected to cause resistance or decreased susceptibility to all or some of the following antibiotics: ampicillin, streptomycin, sulfamethoxazole, tetracycline, gentamicin, ceftriaxone, amoxicillin-clavulanic acid, cefoxitin, ciprofloxacin, and fosfomycin. Ninety-six isolates did not identify predicted resistance. Testing of 5 outbreak isolates using standard antibiotic susceptibility testing by CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory confirmed these results. Some infections may be difficult to treat with commonly recommended antibiotics, and may require another kind of antibiotic.

Here is a good reminder:
