The journey that dairy products undertake starts at the dairy farm and ends at the consumer's table, where milk fluid or other dairy products are consumed. Throughout that process, milk stability is critical, and farms can contribute to a positive consumer experience by managing farm-level factors that can impact the final products. In that aspect, microbiology plays a vital role, so staying up to date with the latest information is essential to reduce dairy product waste. In this episode, featuring Dr. Nicole Martin, we discuss how farm factors, particularly somatic cell count and bacteria plate count, influence the quality of the final products. Additionally, we delve into the significance of cold-resistant bacteria and spore-forming bacteria, as well as consumer decision that contribute to dairy food waste.
