The Short Version
The claim is well-supported. The CDC, AAP, and multiple peer-reviewed studies consistently document that raw milk can harbor dangerous pathogens (Salmonella, E. coli, Listeria, Campylobacter) and has been linked to hundreds of outbreaks, thousands of illnesses, and hundreds of hospitalizations. Unpasteurized dairy causes far more illness per serving than pasteurized dairy. While some observational studies correlate farm-exposure raw milk consumption with lower allergy rates, these findings are non-causal and no authoritative body recommends raw milk consumption based on them.
