Abstract: The poultry sector presents a great speed of expansion when compared to the main productive sectors that make up the meat production complex, around the world and, for poultry farming to reach high productivity, it is necessary to combine nutrition, genetics, management and health. Therefore, sanitary management and health are fundamentally important requirements for the production of meat and laying birds to increase. The objective of this work was to compare the efficiency and effectiveness of three active ingredients (quaternary ammonia, hypochlorite and phenol) used in the disinfection of poultry facilities in the aviary of the State University of Maranhão - UEMA, located on the school farm of Campus Paulo VI; to determine the number of colony forming units (CFU) for each of the active ingredients used in disinfection and identify the genera of bacteria and fungi present in poultry facilities. The work consisted of two stages: in the first, drag swabs were collected from the aviary's poultry facilities during the 15-day sanitary void period (at the exit of the chicken batch, after dry cleaning and after wet cleaning and disinfection) and the second stage, microbiological analyzes of 47 samples were carried out in the Food and Water Microbiology Laboratory of the UEMA Veterinary Medicine course. All of the isolated strains were confirmed as belonging to species of the Enterobacteriaceae Family (11 species of Enterobacteriaceae were phenotypically identified, totaling the 78 isolates obtained from swabs collected) and of the genus Staphylococcus spp. (nine species of Staphylococcus were phenotypically identified, totaling 87 isolates obtained from the swabs collected), which leads to the conclusion that the active ingredients of the disinfectants used (quartenary ammonia, phenol and sodium hypochlorite) were neither efficient nor effective in eliminating these microorganisms.
