Every single day, you take several IQ tests. You just aren't aware of them. Did you look both ways before crossing the street? Did you get a flu shot? Did you buy that $4 organic banana? These are all IQ tests, and the result is either pass/fail. Occasionally, flunking one of these daily IQ tests has very real consequences. The CDC reports that, in August 2016, at least 17 people in Colorado flunked an IQ test when they consumed raw milk and became sick. Milk samples and patient samples both tested positive for antibiotic-resistant Campylobacter jejuni, which causes vomiting and diarrhea.
Many things in life invite skepticism, but the safety of pasteurized milk is not one of them. In fact, the CDC's new report states that unpasteurized dairy products cause 840 times more illnesses and 45 times more hospitalizations than pasteurized products. But guess what? Raw milk sales are rising as people (falsely) believe it's healthier.
In spite of the fact that fewer states allowed the sale of raw (unpasteurized) milk in 2010-2012 than in the previous 2 years, the number of outbreaks of food poisoning linked to its consumption increased from 30 to 51, according to a study in the journal Emerging Infectious Diseases.
