Once the biofilms form on food contact surface, they are quite resistant to antimicrobial agents because of slimy layer formed by bacteria. Wash dishes, pots, pans and utensils and detached parts in hot, soapy water. 1,2 . So, make sure you do the following things: . Biofilms are usually heterogeneous resulting in a specimen that is difficult to visualize. Non food contact surfaces include surfaces throughout the food preparation area that do not come in contact with exposed food. Surface Topography The relationship between surface roughness and the attachment and growth of bacteria may vary. This is because dirty, damp cloths allow bacteria to breed. In K.L. McGuire J. Within biofilms, different bacterial communities cooperate with each other rather than compete. Temperature, pH, electrolytes, and non-electrolyte are also important factors that in turn affects hydrophobicity and surface charges. The steps for proper handwashing are as follows: Wet hands with warm water. You should change dish cloths and tea towels regularly to avoid any bacteria growing on the material. In practice, surface preparation embraces many things, which fall under this term. Even though there are few studies on interaction of bacteriophage with biofilms, there was a report that bacterial viruses could infect starter culture in cheese industry. Pseudomonas fragi is found to be able to grow on stainless steel with thread-like structures. Surface preparation is the essential first stage treatment of a steel substrate before the application of any coating, and is generally accepted as being the most important factor affecting the total success of a corrosion protection system..
