Outbreak-associated Salmonella enterica Serotypes

Outbreak data and case–control studies have linked some serotypes to certain foods or exposures. Information obtained during outbreak investigation is a key tool in understanding which foods are common sources of pathogens contributing to foodborne infections. During outbreak investigations, illnesses can be linked to a particular food by using epidemiologic or laboratory evidence. We analyzed foodborne disease outbreak data to determine associations between food commodities and serotypes to help inform future outbreak investigations, foodborne illness source attribution analyses, and control measures.
