Colony shape tells more about salmonella survival in the feed mill

Norwegian researchers investigating the factors affecting the survival of salmonella in feed mills and fish meal factories found that cellulose was not an important factor in the biofilm matrix but that the different colony shapes affect persistence after drying and nutrient depletion in the biofilm. By Dick Ziggers Salmonella is a well known contaminant of feed and the feed industry, and the authorities and the industry are using large resources in the fight against salmonella. Despite this,
