She was met with skepticism, particularly because she was a woman and did not have a Ph.D. She warned that raw milk should be pasteurized to protect people from various diseases. During the 1920s, scientists around the world made the same findings, and eventually, "Brucella" was confirmed as the disease that caused what was then known as undulant fever and Malta fever. Her findings led to the pasteurization of milk in 1930. As a result, the incidence of brucellosis in the United States was significantly reduced.
Raw milk (CDC), and the Food and Drug Administration (FDA) in the United States, and other regulatory agencies around the world say that potential pathogens from raw milk, including possibly tuberculosis, diphtheria, typhoid, and streptococcal infections, make it potentially unsafe to consume. Similarly, a recent review authored by the Belgian Federal Agency for the Safety of the Food Chain and experts from Belgian universities and institutions concluded that "raw milk poses a realistic health threat due to a possible contamination with human pathogens. It is therefore strongly recommended that milk should be heated before consumption. With the exception of an altered organoleptic
