Abstract

Bacteria of the genus Salmonella are pathogens that infect several animal species, including humans. Certain serovars of Salmonella enterica can colonize the digestive tracts of poultry and proliferate without causing evident clinical signs. However, these pathogens pose a risk to public health, as poultry-derived foods become potential sources of human infection and result in economic losses for poultry farming. Disinfectants with antimicrobial properties are employed for sanitization in pathogen control programs within poultry production, including bacteria of the genus Salmonella. However, little is known about the susceptibility of Salmonella spp. to these molecules and the link between biocides and antimicrobial resistance. In this context, the present study aims to evaluate the Minimum Inhibitory Concentration (MIC) of disinfectants based on quaternary ammonium, peracetic acid, sodium hypochlorite, and glutaraldehyde, agents widely utilized in farms and food industries, as well as hospital environments.
