Ontario Agricultural College researcher Dr. Keith Warriner explained the link between raw milk and tuberculosis to CBC News, following the release of a report that found the drink caused the deaths of Indigenous children at a residential school. 

Warriner said it wasn’t until the early 20th century that people began to view and accept raw milk as a cause of one form of tuberculosis, and that pasteurized milk only became federally mandated in 1991. 

A professor in the Department of Food Science, Warriner researches food safety and microbiology with an emphasis on food borne viruses like listeria.
