    Research output: Book/ReportReport


    The research work in DairyNET - Hygiene control in dairy environment (P00027), which is the third Nordic project in dairy hygiene funded by the Nordic Innovation Centre (formerly the Nordic Industrial Fund), has focused on hygiene and quality issues relating to raw milk, process surfaces, equipment and utensils, process waters, air and final products e.g. semi-hard cheese as well as contamination routes for Listeria from the cow shed to that the products leave the dairy. The 3 synergy tasks common for all national projects dealt with detection of cleaning agent or disinfectant residues left on process surface before production start-up, visualisation of organic soil in problematic spots using a UV-light based method to pinpoint poor hygienic design and detection of fungal contamination on cheese using CREAD agar. The work was carried out in the Nordic dairies Arla Foods, Milko, Nordurmjólk, Norrmejerier, Skåne mejerier, TINE and Valio Ltd together with the research organisations BioCentrum-DTU, DTI, IFL, KTH, Matforsk, SIK, the University of Akureyri and VTT Biotechnology as well as the following suppliers of chemicals, reagents and equipment: Finnsonic Oy, JohnsonDiversey, Lagafors Fabriks AB, Mjöll, TetraPak Nordic Processing and Orion Diagnostica Oy from May 2001 to October 2004. New procedures in hygiene based on the project findings have been implemented in processing at the dairies.
