MANFREDI, Eduardo A  and  RIVAS, Marta. Food poisoning outbreak in a kindergarten in the Province of Buenos Aires, Argentina. Rev. argent. microbiol. [online]. 2019, vol.51, n.4, pp.354-358. ISSN 0325-7541.  http://dx.doi.org/10.1016/j.ram.2018.08.008.

On November 27, 2008, a foodborne disease outbreak associated with the consumption of chicken salad occurred in a kindergarten in the District of Hurlingham, Province of Buenos Aires. Thirty-seven children and 10 adults with gastrointestinal symptoms were affected. Five children were hospitalized with signs of dehydration, one of them requiring intensive care. Staphylococcus aureus subsp. aureus was isolated from the mentioned food in 4 out of 5 stool specimens from the patients, and in 3 out of 5 food handlers (nose of food handler #1, hands of food handlers #2 and 3). The isolates carried the genes coding for enterotoxins SEA and SED. The macrorestriction patterns showed 100% similarity by pulsed-field gel electrophoresis using the SmaI enzyme. A timely outbreak investigation allowed us to identify the causative agent of the food poisoning as well as the failures in food processing and to implement corrective measures.

Keywords : Staphylococcus aureus; Enterotoxins; PCR; SmaI-PFGE.
