Resistance of pathogenic and spoilage microorganisms to disinfectants in the presence of organic matter and their residual effect on stainless steel and polypropylene

The antimicrobial activity of the disinfectants tested against pathogenic and spoilage microorganisms was affected according to the type of organic matter present. SANICIP Q5 had a greater residual effect than the other disinfectants evaluated. Moreover, the residual effect of a disinfectant is greater on SS than on PP-B and is dependent on the microorganism tested.
