Between 1993 and 2006 more than 1500 people in the United States became sick from drinking raw milk or eating cheese made from raw milk. In addition, CDC reported that unpasteurized milk is 150 times more likely to cause food borne illness and results in 13 times more hospitalizations than illnesses involving pasteurized dairy products.
Whether raw milk is safe to drink depends on the health of the cows, the handling of the milk; the cleaning and sterilization of equipment, and storage time and temperature. Pasteurized which removes over 99% of the bacteria significantly reduces the chance of becoming sick from contaminated milk.
Federal laws prevent the interstate sale of raw milk but many states allow sales within the state. The push, if you want to call it that to allow raw milk sales across the country comes from small dairy farms struggling to survive, health food addicts that believe in the magic properties of raw milk, and right wing nuts who want to abolish all food safety laws.
Pasteurized milk is also made from raw milk and is also sometimes included in raw milk stats.

The study was called “Nonpasteurized Dairy Products, Disease Outbreaks, and State Laws, 1993–2006” It says in the abstract: “Nonpasteurized products caused a disproportionate number (≈150× greater/unit of product consumed) of outbreaks” Nowhere in the results do you find 150x or “greater/unit of product consumed”

It says “1% of U.S. residents consume raw milk” which is from the 2002-2003 FoodNet Population Survey. It's 3% in the 2006-2007survey. It refers to outbreaks not cases. Raw milk outbreaks average 20 cases per outbreak. Pasteurized milk averages 1,645 cases per outbreak.

Why just 1993–2006? In 1985, there were over 16,000 confirmed cases of Salmonella infection that were traced back to pasteurized milk from a single dairy. From 1993–2006 there were only 2,098 all together.

In 2007 the number of raw milk consumers tripled. They all ready knew this for 4 yrs. This study only involved “outbreaks in which investigators reported whether the product was pasteurized or raw.” In most outbreaks involving pasteurized dairy, investigators do NOT report that the milk is pasteurized; they just say “milk” or “cheese.”
-----
It compared “raw milk AND raw milk products” to just “pasteurized milk” and not pasteurized milk products. When a person goes to the hospital with a food-borne illness, the first question asked is “Did you drink raw milk?” If the person answers yes, he or she is immediately admitted and no further questions are asked. Most of these people are out in just a day or two despite the horrific safe record hospitals have.

The association is completely arbitrary. We don't know if the cause is even bacterial, which bacteria if it is, or where it came from. All these bacteria can be pasted by human contact. Some are even airborne or in soil and most if not all are already in our bodies. When they aren't in our body that could be called an imbalance. Look up Fecal microbiota transplantation (FMT) stool poop. So we go from 150x to 50x to 5x to 1.35x to 0.7x before we even consider that fact that most pasteurized milk outbreak-associations are unreported and raw milk outbreak-associations are over reported.
