In this follow-up conversation with Raw Farm's CEO & Founder Mark McAfee, we explore the nuanced differences between raw milk and UV pasteurization technology. Mark shares his expert perspective on UV treatment as a middle ground between raw milk and traditional heat pasteurization, explaining why it preserves some bioactives while eliminating the beneficial bacterial diversity that makes raw milk unique.

We dive into the technical aspects of milk safety, including Raw Farm's advanced PCR testing protocols that provide daily pathogen screening, and discuss the practical challenges of scaling raw milk production. Mark also shares his guide on how to source clean raw milk from your local farm.
