Human S. typhimurium infections linked to exposure to microbiology laboratories
CDC and public health officials in several states have identified a multistate outbreak of Salmonella Typhimurium infections linked to various clinical, commercial, and teaching microbiology laboratories. Twenty-four people infected with the outbreak strain of Salmonella Typhimurium were reported from 16 states.
Six ill people were hospitalized. No deaths were reported. This strain of Salmonella Typhimurium has previously been associated with infections linked to microbiology laboratory exposure in 2011 and 2014. Laboratory-associated salmonellosis continues to be a public health problem. This outbreak is a reminder that bacteria used in microbiology laboratories can sicken people who work in labs.
