InhibioList was a collaboration between the farming industry and research institutions. It has proven to be both difficult and expensive to keep food production premises free of Listeria, partly because the bacteria can survive in biofilm, which makes them very resistant. Listeria can also be a problem on the live fish; discoveries have been made, among other things, in waiting cages, on transport pipes and in well boats. The project has therefore also investigated biofilm formation in seawater and with various marine cultures. The fish slaughterhouses in the project regularly took bacteria samples at defined locations in the company and the samples were tested for the presence of Listeria bacteria. Samples with Listeria were serotyped and examined using "genetic fingerprinting" methods to detect any house strains that survive in the company over time and pose a risk of cross-contamination of products. Most strains had either serotype IIa or IVb. In the main, the strains with serotype IIa are good biofilm formers, while the strains with serotype IVb are poor. Strains that were good biofilm formers were used in product development. Laboratory tests to investigate the effect of different disinfectants on Listeria strains in biofilm were established, and the effectiveness of different disinfectants on potential house strains investigated. The idea behind the product development was to use a group of substances that counteract the formation of biofilm, but at the same time are environmentally friendly, as an addition to liquid products, in coating or polymer. Laboratory studies on the ability of the various Inhibio substances to inhibit biofilm production by Listeria from the factories were carried out. Substances that gave a good effect in solution were cast into different coatings and in different types of plastic. These were examined in various biofilm tests to identify materials with a good effect against biofilm formation. The project succeeded in developing polymer prototypes with antibiofilm properties. The developed prototypes showed effectiveness against Listeria and marine microorganisms and have the potential to be used in various places in the aquaculture production chain, such as e.g. in tanks and equipment, cages, in well boats or in building structures. The project has mapped regulatory conditions for future Inhibio products and, in that context, has had the active substance investigated with regard to ecotoxicity and biodegradability. Until the technology is ready to start the industrialization process, i.e. has progressed somewhat further in the qualification process, there will be no need for approvals.
