The dairy industry needs to move toward production of high quality, good tasting, extended shelf life (less than 14 days) fluid milk products to enable our products to compete in the marketplace with shelf-stable convenience beverages (e.g., soft drinks, juices and sports drinks). It is clear that the bacterial quality of raw milk will have an increasingly important influence on final product quality. Overcoming the newly recognized hurdle presented by spore-forming bacteria will require a joint effort between producers, haulers and processors. Our current research goal is to better understand how bacterial contaminants enter the milk supply at the dairy plant and at the farm level. This information will enable development of management and sanitation practices for reducing bacterial contamination, which will ultimately increase consumer satisfaction with our products.
