title: ASalmonella EntericaSubsp.EntericaSerovar Enteritidis Foodborne Outbreak after Consumption of HomemadeLasagne.
abstract: In the latest year, and also in 2013,Salmonellawas the most frequently detected causative agent in foodborne outbreaks (FBOs) reported in Europe. As indicated in EFSA report (2015) the serotypes mostly associated to FBOs areS.Typhimurium and Enteritidis; whileSalmonellaTyphimurium is generally associated with the consumption of contaminated pork and beef, FBOs due toSalmonellaEnteritidis are linked to eggs and poultry meat. In this study it is described the investigation of a domestic FBO involving four adults and linked to homemadelasagne. Investigations were performed to determine the relatedness ofSalmonellastrains, identify the sources of infection, and trace the routes ofSalmonellacontamination in this FBO.Salmonellastrains were isolated in 3 out of 4 patient stool samples and fromlasagneand all of them were serotyped asS.Enteritidis. Pulsed-field gel electrophoresis (PFGE) analysis revealed the genotypical similarity of all the strains. Although serotyping and PFGE analysis identified the common food source of infection in this FBO, it was not possible to determine how or at what point during food preparation thelasagnebecame contaminated withSalmonella.
