Cockroaches can carry and disseminate microorganisms. The objective of this study was to investigate the presence of coagulase-positive Staphylococcus, Salmonella spp. and Listeria monocytogenes from cockroaches in residential kitchens. The study was conducted from March to December 2010 and involved 120 inspections. In each kitchen, three traps were placed and left for 24 hours. The samples were subjected to microbiological analysis for Salmonella sp., L. monocytogenes and coagulase-positive Staphylococcus. The insects were also quantified, sexed and classified. Twenty-nine cockroaches were collected, none of which was contaminated with Salmonella sp., coagulase-positive Staphylococcus or L. monocytogenes. However, microorganisms of the genus Citrobacter sp. (23.52%), Enterobacter sp. (23.52%), Proteus sp. (23.52%), Serratia sp. (5.88%), Flavimonas sp. (2.94%), Morganella sp. (2.94%), Providencia sp. (2.94%), Alcaligenes sp. (2.94%), Staphylococcus sp. (8.82%) and Acinetobacter (2.94%) were found. Thus, we observed that cockroaches can carry microorganisms which reinforces the importance of the control of these insects.
