Mapeamento de risco para presença de Listeria spp. em uma indústria de pizzas

Abstract

The bacteria of the genus Listeria spp. Are psychotrophic pathogenic microorganisms, their natogenicity occurs even at low colonization rates, causing severe diseases with high mortality rates in humans. The Listeria spp. Can form biofilms, so they can contaminate the surface of equipment, utensils and drains present in the industrial process, and may form microbial biofilms capable of colonizing internal parts of the equipment, becoming persistent in the productive environment. The objective of this work was to map the presence of microorganisms of the genus Listeria spp., As a way to investigate and demonstrate the main contamination points, and later to discuss ways to minimize this microorganism in the productive environment. During the 10- month period, samples were collected to verify the presence of listeria in equipment and also in the final product, where the results were verified and analyzed, with possible corrective actions were suggested according to the results, which demonstrated a percentage Higher contamination through inadequate food handling and possible flaws in the PPHO procedure, which has been developed a risk map, demonstrating the areas that require attention, since they have already shown positivity for the microorganism listeria, which can be used as a tool Quality control of this industry. The critical areas resulting from the work, are usually areas that have cooling and intense flow of people and inputs.
