Multiple-serotype Salmonella outbreaks at two prisons in Arkansas were linked to problems with food preparation, hand washing and food safety training, according to a report by the CDC and the Arkansas Department of Health.
On Aug. 7, 2012, the Arkansas Department of Health began an investigation after learning of a diarrhea outbreak among 260 inmates in prison A. Stool specimens from seven inmates tested positive for Salmonella, and three serotypes were identified: S. anatum, S. cerro and S. heidelberg.
