Salmonella Heidelberg is highly prevalent in poultry. This pathogen is associated with multidrug-resistant and biofilm-producing isolates, both of which are associated with increased persistence in food-processing facilities. Cleaning and disinfection processes are essential for guaranteeing hygienic and sanitary conditions. Several traditional compounds used in poultry facilities have shown decreased biofilm removal efficiency. This study aimed to evaluate the antibiofilm activity of four commercially available products (three detergents and one disinfectant) against S. Heidelberg biofilms formed on polypropylene surfaces. All S. Heidelberg strains produced biofilms on polypropylene surfaces at 28 °C and approximately 70% formed biofilms at 37 °C. The Biofilm and biomass production by S. Heidelberg was significantly lower (p<0.05) after using the alkaline detergent, than after the control and other treatments. There were no significant differences (p>0.05) between the other treatments. The alkaline detergent resulted in a reduction of more than 90% in the biofilm-forming strains at 28 °C.
