The Dirty Truth: How Biofilms in Milking Equipment May Fuel Mastitis in Dairy Cows and Threaten Dairy Hygiene

Biofilms, resilient bacterial communities encased in a self-produced matrix, pose a significant threat to dairy farming. These microbial formations develop on surfaces that are frequently exposed to moisture and organic material, making milking equipment an ideal breeding ground. Once established, biofilms are notoriously difficult to remove, resisting standard cleaning protocols and allowing pathogenic bacteria to…

Raw Milk Testing for the 21st Century: Key Parameters for Achieving High Quality 

The quality of processed dairy products is inextricably tied to the quality of raw milk at production, and throughout pre-processing storage and handling. Pasteurization, while quite literally a lifesaver, is no magic bullet when it comes to improving quality. As domestic and international markets for US dairy products evolve, expectations of increasing shelf life are…

Prevalence of Cold-tolerant Spore-forming Bacteria in the Milk Supply 

The shelf life of pasteurized fluid milk is challenged by bacterial contamination that enters the finished milk supply through two portals: a) contamination by Gram-negative psychrotrophic bacteria during processing after pasteurization; and b) contamination by Gram-positive spore-forming bacteria that enter primarily through the raw milk supply. In today’s processing environment, where post-pasteurization contamination is largely…
