Presence of microorganisms from isolated Megaselia spp. in foodservice establishments

Introduction: the transmission of harmful pathogens by arthropods is an increasing health concern. More concretely, flies are known to be able to transmit the infectious agent mechanically. Objective: the present work shows a case report occurred from foodservice establishments where were isolated and identified, at the first time, Megaselia spp. in the food preparation place. Furthermore, microorganisms were analyzed from these flies. Method: it is based in entomological and microbiological analysis. Results: mesophilic aerobic flora and Enterobacteriaceae were found in all the samples, exceeding the limits established from food commodities on 41.7% (5/12) for mesophilic aerobic bacteria and 66.7% (8/12) for Enterobacteriaceae. Furthermore, 25% (3/12) of analyzed flies were found positive to Escherichia coli, data that can be linked with the microbiological food results. The most surprising results were the presence of S. aureus in 66.7% (8/12) of the analyzed flies. Conclusions: a binomial relationship among Megaselia spp. and bacteria is demonstrated being an important study to demonstrate that must be checked more hygienically measurement in foodservice.
