Microorganisms are far more sensitive to disinfectants once they have been detached from the surface to which they were adhering. Mechanical action with brushes and medium and high-pressure jets is recognized as being highly effective in eliminating biofilm (Holah et al. 1990b;Carpentier and Cerf 1993). Acid products are no more effective than hot water, while chlorinated alkaline detergents are the most effective for detaching biofilm, followed by nonchlorinated alkaline detergents (Carpentier and Cerf 1993). Peroxides have been reported to be effective for the removal of bacteria biofilms and widely used in the food industry (Fatemi and Frank 1999; Stopforth et al. 2002).
