Within biofilms microorganisms are generally well-protected against the influence of disinfectants, antibiotics [1] and the host immune system  and as a consequence biofilms are extremely difficult to eradicate . As such, they cause major problems in medicine, agriculture, (food) industry and the household environment. Biofilms are problematic in particular food industry sectors such as brewing, dairy processing, fresh produce, poultry processing and red meat processing . Reduction of bacterial contamination of poultry products during processing is of major concern among processors and those concerned with food safety. Biofilm can grow on abiotic surfaces of different equipment in food industry and poses a risk to human health. Furthermore, food processing surfaces and equipment may be favorable environments for Pseudomonas biofilm formation. This is why many potential Pseudomonas species virulence factors have been identified using animal models of infection, including those that allow bacteria to move over, attach to, and effectively colonize mammalian tissues, and secreted enzymes and toxins that allow Pseudomonas to cross tissue barriers and evade host immune defences. In this background, attention should be focused on better understanding the factors influencing production and distribution of the biofilm in certain species of Pseudomonas which had a rapid biofilm evolution, adaptation and resistance.
