A Community Outbreak of Salmonella enterica Serotype Typhimurium Associated With an Asymptomatic Food Handler in Two Local Restaurants

Abstract

Between January and April 2012, the city of Long Beach Department of Health and Human Services investigated an outbreak involving 19 case patients who had tested positive for Salmonella enterica serotype Typhimurium with indistinguishable pulsed-field gel electrophoresis patterns. All cases were residents of or traveled to the city of Long Beach, California, during their incubation period, and the majority of patients reported eating at one of two restaurants in Long Beach. This article describes the outbreak investigation that traced the source to an asymptomatic food handler working at both restaurants and highlights the importance of maintaining a high index of suspicion for food handlers when faced with local outbreaks of diarrheal illness.
