A foodborne outbreak of Salmonella enteritidis vehicled by duck and hen eggs in southern Italy.
A foodborne outbreak of Salmonella enteritidis PT4 is described. This microrganism was detected in a home-made dessert, in the duck and hen eggs used for its preparation and in faecal samples of six persons involved in the outbreak. PCR ribotyping revealed that all the strains shared a profile of S. enteritidis never previously identified in southern Italy and quite different from that of the strains simultaneously isolated in the same geographic area. The possible identification of a clonal variant of S. enteritidis PT4 host-adapted to duck is hypothesized.
