Outbreak Advisory

  • CDC, many state departments of health and agriculture, and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service are investigating eight multistate outbreaks of human Salmonella infections linked to contact with live poultry in backyard flocks.
    • These outbreaks are caused by several kinds of Salmonella bacteria: Salmonella Braenderup, Salmonella Enteritidis, Salmonella Hadar, Salmonella I 4,[5],12:i-, Salmonella Indiana, Salmonella Infantis, Salmonella Mbandaka, and Salmonella Typhimurium.
  • As of May 25, 2017, 372 people infected with the outbreak strains of Salmonella have been reported from 47 states.
    • Illnesses started on dates ranging from January 4, 2017 to May 13, 2017.
    • 71 ill people have been hospitalized, and no deaths have been reported.
    • 36% of ill people are children younger than 5 years.
  • Epidemiologic, traceback, and laboratory findings link the eight outbreaks to contact with live poultry, such as chicks and ducklings, which come from several hatcheries.
    • In interviews, 190 (83%) of 228 ill people reported contact with live poultry in the week before illness started.
    • People reported purchasing live baby poultry from several sources, including feed supply stores, websites, hatcheries, and from relatives.
  • Contact with live poultry and the areas where they live and roam can make people sick with Salmonella infections. Chicks, ducklings, and other live poultry that look healthy and clean can still carry Salmonella bacteria.
  • Outbreaks( linked to contact with live poultry have increased in recent years as more people keep backyard flocks. In 2016(, a record number of illnesses were linked to contact with backyard poultry.

  • CDC, multiple states, and the U.S. Food and Drug Administration (FDA) are investigating a multistate outbreak of Shiga toxin-producing Escherichia coli( O157:H7 (STEC O157:H7) infections.
    • Twelve people infected with the outbreak strain of STEC O157:H7 have been reported from five states.
    • Six ill people have been hospitalized. Four people developed hemolytic uremic syndrome, a type of kidney failure, and no deaths have been reported.
    • Eleven of the 12 ill people in this outbreak are younger than 18 years old.
  • Epidemiologic evidence available at this time indicates that I.M. Healthy brand SoyNut Butter is a likely source of this outbreak. I.M. Healthy brand SoyNut Butter may be contaminated with E. coli O157:H7 and could make people sick.
  • CDC recommends that consumers do not eat, and childcare centers, schools, and other institutions do not serve, any I.M. Healthy brand SoyNut Butter varieties and sizes, or I.M. Healthy brand granola coated with SoyNut Butter.
    • Even if some of the SoyNut Butter or granola was eaten or served and no one got sick, throw the rest of the product away. Put it in a sealed bag in the trash so that children, pets, or other animals can’t eat it.
  • This investigation is ongoing and quickly changing. CDC will provide updates as more information becomes available.
