This bill aims to prohibit federal departments, agencies, or courts from interfering with the interstate traffic of unpasteurized milk and milk products packaged for direct human consumption. It specifically prevents federal action, such as deeming these products adulterated or misbranded, solely because they are unpasteurized, thereby removing a significant federal barrier to their movement across state lines. This non-interference applies under specific conditions, ensuring that federal authorities cannot restrict products based solely on their unpasteurized status if state laws are followed. For federal non-interference to apply, the milk or milk product must originate from a state that permits its distribution for direct human consumption, including retail sales or "cowshare" arrangements. The product must also be produced, packaged, and transported in full compliance with all applicable laws of that originating state, including specific labeling and warning requirements. Furthermore, the unpasteurized milk or milk product must be destined for another state that similarly allows its distribution for direct human consumption. Importantly, the bill explicitly states that it does not preempt any State law, ensuring that states retain their authority to regulate unpasteurized dairy within their borders.
