Abstract

Dishcloths or also called dish towels are utensils that have many uses in domestic kitchens. But a dishcloth can be a means of contamination, mainly because it remains humid, being one of the great attractions to bacteria. And its participation in cross-contamination can be one of the biggest problems because it contaminates other clean objects. The aim of this study was to evaluate contamination by Staphylococcus aureus, Coliformes and Salmonella spp., in dishcloths used in domestic kitchens. For the methodology, 30 samples of dishcloths were collected in order to be processed for the cultivation and identification of bacteria, in specific culture media and later the analysis of the resistance profile to Beta- Lactamicos was carried out. After that, the study of methods for descontamination of dish towels was carried out. The results showed that the analyzed cloths were contaminated mainly with bacteria from the family Enterobacteriaceae, of the genres Enterobacter, Citrobacter e Klebsiella, in addition to Escherichia coli and a sample was contaminated with Salmonella spp. The best way found to decontaminate dishcloths is to use 0.1% Sodium Hypochlorite. Regardless of the number of days of use and activities carried out, it is necessary to properly clean the dishcloths. In addition to separating cloths for each use in the kitchens.
