                                According to a 2024 study, the vigorous fermentation process in raw milk kefir resulted in a significant reduction of E. coli, suppressing its growth by nearly 5 log units. This reveals that properly made kefir possesses strong antimicrobial properties that fight against unwanted pathogens.
