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.
