What started as an isolated salmonella outbreak at a Mustang, Oklahoma school has now become a multi-state outbreak investigation. In late September, 10 cases of salmonella were reported from a Mustang city school district in Oklahoma. By the end of the month 15 caseshad been identified from three different counties (Canadian county, Oklahoma county, and Carter county). Several days later, the outbreak investigation had expanded to the states of Iowa and Nebraska who were each reporting several cases of a similar strain of salmonella. The strain identified in the Oklahoma cases has been confirmed as Salmonella Java. Recent news reports state that there are now 14 confirmed cases from Mustang city schools, 3 additional suspect cases throughout the state, and several being investigated in Iowa and Nebraska. The source of the outbreak has not yet been identified.
