Figure 1 Blanketing creates a physical and biological barrier that prevents pathogens from growing on the same surface Figure 2 Biosurfactants act like detergents to break down pathogenic biofilms Figure 3 Exopolysaccharides interfere with the ability of pathogens to produce biofilms or stick to a surface Trouw Pet Nutrition Outlook Volume 4 8 Probiotics and pet food Biofilm formation Biofilm is a matrix of carbohydrates proteins and other compounds produced by bacteria It helps bacteria stick to surfaces and protects them from the surrounding environment As biofilms age cells break of and become aerosolized spreading to other areas of the plant Biofilms are dificult to remove with routine cleaning and sanitation Accessibility Any area not routinely cleaned or sanitized whether piping that runs under equipment crevices that cannot be scrubbed or areas high above the facility floor has the potential to harbor pathogenic bacteria Probiotics as part of the food safety solution Probiotics not only boost animal health directly They can also provide benefits when companies use them to establish and maintain healthy microbial populations in manufacturing plants Probiotics have a number of mechanisms by which they can enhance food safety in the manufacturing environment These include blanketing biosurfactant production and exopolysaccharide production Blanketing involves populating a surface with probiotics and allowing them to take hold there This blanket is a physical and biological barrier that prevents pathogens from growing on the same surface but allows probiotic bacteria to proliferate Figure 1 Biosurfactants act like detergents They change surface tension breaking down pathogenic biofilms and preventing new pathogenic microbes from adhering to the surface Figure 2 Exopolysaccharides interfere with the ability of pathogens to produce biofilms or stick to a processing surface Figure 3 Because they are living organisms probiotics can grow and spread into areas of the manufacturing
