Another organism that survives pasteurization is paratuberculosis, in milk. It is commonly found in commercial dairy herds. In my opinion, this is alarming.

Many consider it to be a candidate for the cause of Crohn’s disease. Johne’s disease, which occurs in a subset of cattle infected by paratuberculosis, bears many similarities to Crohn’s disease.

When Crohn’s disease was first described, it was believed to be an intestinal tuberculosis, though tests seemed to counter this idea; to this day, it remains difficult to test humans for paratuberculosis infections.
