Abstract

The objective of this study was to evaluate the efficacy in vitro of disinfectants commonly used in sanitizing poultry farms and biodegradable disinfectants against Salmonella serotypes isolated from poultry farms in the state of Parana, Brazil. The experiments were performed using the contact time of 20 minutes and disinfectants tested in three concentrations recommended by the manufacturer, half the recommended concentration and twice the recommended concentration, as well as the presence and absence of organic matter. In general, all disinfectants caused significant reduction in the microorganisms counts compared to the control. In the absence of organic matter, disinfectants based on organic acids showed the best results against the serotype Gallinarum biovar Gallinarum and disinfectants based onglutaraldehyde and sodium hypochlorite against the serotypes Typhimurium and Intantis. In the presence of organic matter, as commonly found in the poultry environment, it was observed that all disinfectants showed decreased effectiveness, and the disinfectant based on organic acids had the lowest CFU counts. Accordingly, the disinfectant based on organic acids proved to be potential alternative for use in poultry due to effectiveness in controlling Salmonella serotypes isolated from poultry.
