Introduction Certain bacteria develop a fortress or biofilm in the environments they colonize which provides shelter from antimicrobials and other sanitation procedures.
A biofilm is formed when planktonic (or free/stand-alone) cells in an aqueous environment adopt a multicellular lifestyle by attachment to, and colonization of, a solid surface (Claessen et al., 2014). This may occur on a submerged surface or at the air-liquid interface (known as pellicle formation; Wu et al., 2012).

Reilly, Ph.D. Every food processing plant contains a biofilm somewhere in the facility or on equipment. No matter how well the facility cleans and sanitizes, the biofilm may continue to be a source of pathogens and may manifest as disease in animals or humans. The intent of this article is to offer a solution to prevent, reduce or eliminate this biofilm/pathogen from the food processing plant when there are no other possible corrective actions.

FOOD SAFETY NEWS 23/01/14 Salmonella Biofilms Extremely Resistant to Disinfectants. Researchers have discovered that common disinfectants face an uphill battle killing Salmonella once it has had the time to form a biofilm – a community of cells that attach to each other and a surface, increasing the density of bacterial growth and providing support from harsh environments.
Researchers at the National University of Ireland, Galway, allowed Salmonella enterica cells to grow for seven days before applying three types of disinfectant — sodium hypochlorite, sodium hydroxide and benzalkonium chloride. They found that none of the disinfectants was able to kill the cells after that amount of time. Even soaking the biofilms in disinfectant for an hour and a half failed to kill them. The strains she tested were able to form a biofilm on glass, steel, polycarbonate plastic, glazed tile and concrete.

Food Control 31 (2013) 572e585 Biofilm formation in food industries: A food safety concern. FOOD PROCESSING TECHNOLOGY 16/09/13 Reducing Bacterial Biofilms on Food Factory Floors. Bacteria that persist within the food and drink manufacturing centres are those which survive and grow under the prevailing environmental conditions (temperature, product residues and moisture levels, etc) and remain viable and attached to surfaces following cleaning and disinfection.
Careful consideration should be given to the selection of surface materials and the choice of cleaning regimes if you wish to minimise the presence of biofilms on surfaces within food factory environments. Food factory floors are exposed to forklifts and machinery as well as food and liquid contaminants so the demands on the flooring performance are much higher than is required in most commercial settings. A particular favourite within food factory companies is non-slip epoxy or polyurethane resin systems. While these systems are quick and easy to install, the material emits high levels of odours and has a low life expectancy, adding to a company’s maintenance costs and inconveniences.

Technologie SLIPS : les biofilms ont-trouvé leur maître ? Un communiqué de Harvard School of Engineering and Applied Science du 30 juillet rapporte une nouvelle qui sans doute fera du bruit, « Un nouveau revêtement expulse les biofilms pour de bon » La technologie « Slippery » (ou de glissade) a montré qu’elle peut prévenir plus de 99% du slime bactérien dangereux de se former sur les surfaces.
Les biofilms ne vont plus avoir de support solide pour exister en tant que tel. Une équipe de chercheurs de Harvard a mis au point un habile moyen pour empêcher les communautés bactériennes inopportunes de ne jamais se former sur une surface. Les biofilms se collent sur à peu près tout, des tuyaux en cuivre, des coques de navires en acier aux cathéters en verre. Les revêtements visqueux ne sont pas que juste une nuisance, cela entraîne une efficacité énergétique diminuée, une contamination de l'eau et des aliments, et surtout dans les hôpitaux, des infections persistantes. . « Les biofilms ont été incroyables à nous déjouer.

Yet, until a few years ago, it was not at all understood. Even now, most growers don't understand what biofilm is, what problems it causes, and most importantly, how to control it.

Stabilized & activated food grade hydrogen peroxide:New zero residue water treatment and biofilm control solution Biofilms are the most underrated threat to successful Horticultural production, especially in re-circulated water systems.
Biofilms can form within days and are a safe-haven for pathogen multiplication and a constant source of infection for irrigated crops. Over and above the fact that biofilm blocks drippers, 80% of all plant infections come through the water source, almost always as a consequence of biofilms. Plant immune systems can survive attacks by individual planktonic pathogens on a daily basis, but when a biofilm sloughs and releases hundreds of thousands of pathogens at once into the irrigation water, the plant's immune system becomes overwhelmed and infection rapidly follows.

FOOD CONTROL - JUNE 2013 - Biofilm formation in food industries: A food safety concern. Abstract Foodborne diseases have always been a threat to human health. They are considered an emergent public health concern throughout the world.
Many outbreaks have been found to be associated with biofilm. It is well documented that biofilm has become a problem in food industries as it renders its inhabitants resistant to antimicrobial agents and cleaning. Embor200843.pdf.

Comprehensive Reviews in Food Science and Food Safety Volume 11, Issue 2, pages 133–147, March 2012 Biofilm Formation in Milk Pr. Abstract Abstract: Bacteria in milk have the ability to adhere and aggregate on stainless steel surfaces, resulting in biofilm formation in milk storage tanks and milk process lines. Growth of biofilms in milk processing environments leads to increased opportunity for microbial contamination of the processed dairy products. These biofilms may contain spoilage and pathogenic microorganisms. Čapla et al. 2012 : 1 (February Special issue) 733-741 SANITATION PROCESS OPTIMALIZATION IN RELATION TO THE MICROBIAL BIOFILM OF.
