Milking hygiene in automatic milking systems must meet exceptionally stringent standards. The milk must be safe in terms of its bacteriological quality; primary contamination must be prevented by consistently good udder health, and secondary contamination minimised by hygienically sound udder cleaning and interim cleaning of the teat cups and udder-cleaning equipment. The effectiveness of the cleaning and disinfection of the udder-cleaning equipment and teat cup was bacteriologically investigated on dairy farms in the German state of Hesse by means of swab samples. At the same time, milk samples were taken in a sterile manner from the milk separator and milk storage tank for differentiated quantitative bacteriological analysis. The results of the cell-count and bacterial-count analyses of the milk supplied by the AMS farms are shown. The results reveal hygienic weak spots: interim cleaning and disinfection of the components is unsatisfactory, which is in turn reflected in the bacteriological quality of the milk. There is a failure to effectively prevent the transmission of udder pathogens, with a tendency towards higher cell counts as a consequence. The efficiency of the cleaning and disinfection of the milking-machine components in automatic milking systems is in urgent need of improvement, in order to prevent the transmission of udder pathogens on the one hand, and to ensure a high level of food safety as well as compliance with food-hygiene legal requirements on the other.
