The project ‘DairyNET – Hygiene control in dairies’ was built both on common synergy tasks performed in all Nordic countries and on national research studies. The synergy tasks dealt with rapid detection of cleaning agents and disinfectants residues, detection of organic soil in processing equipment hot spots and detection of moulds contaminating cheese. The national research dealt with a checklist for hygiene control; milk quality through the whole process line; air quality; contamination routes for Listeria; quality of process waters; efficiency of CIP procedures; hygiene in supply systems; ultrasound cleaning procedures; bacterial resistance to disinfectants; hygienic design and integrated hygiene systems.
