Resumen
To obtain a quality product it is necessary to control several factors involved in food production such as the production environment. The aim of this study was to evaluate the microbial contamination on surfaces of equipment, the handlers, water and air from different sectors of production of a poultry feed mill, located in the state of Minas Gerais. A total of 90 water samples were collected 65 samples on the surface of handlers as samples, 88 on the surface of production equipment and 93 samples in ambient air. It was observed high levels of contamination on the surfaces of the hands of manipulators and production equipment (6.1x104 CFU g-1), highlighting the coliform group. Particles were observed in air, with high levels of bacterial contamination (3.8x104 CFU g-1) and fungi (5.3x103 CFU g-1). The species mesophilic microorganisms were found in the water. It was concluded that the high levels of contamination found in the low agents was owed control of the production system of industry. This fact resulted in increased risk of microbial contamination of the final products and handlers.
