I tend not to argue safety with folks who try to convince me that I am putting my kids at risk. I just tell them my story and why it led me to MY choice: when my husband and I learned of the benefits of raw milk, we did have some concerns because of the broad view that it is very unsafe. He was a medical student at the time and I hold a BS in biochemistry and worked in scientific research. Therefore we felt confident we could sift through the literature ourselves rather than relying on secondary information. What surprised us is what we DIDN'T find. In the dairy industries own journals, we found NO research on safety of any sort. With all the media buzz about safety of dairy being of mega-importance, it was odd to me that ongoing studies were absent in our findings. What we DID find was study after study about how to best market (pasteurized) milk to the masses. When we got to the study where they had a panel of taste-testers see what they thought of pasteurized milk from cows with mastitis, determining that YES they could sneak this milk in but it would need a slightly shorter shelf life, we knew we were done with our research and done with pasteurized milk forever.
This is the story I told my state representative when I met with her about Minnesota's Fair Milk Access Bill when she asked me about safety. I will not tell another family how to determine what foods are safe and nourishing for their family, but the above is how our family decided on which milk to drink. I now advocate that ALL milk drinkers do their own research. Drinking pasteurized milk is a choice too -- so I feel when people ask me to "learn about the dangers of raw milk", its fair for me to urge them to learn more about their choice too.
Another important aspect in any food safety discussion is "terrain". For us raw milk is part of a nourishing, whole foods diet. We want our bodies' terrains to be able to handle any pathogens that we may come into contact with. When we start sterilizing our food supply, we take away the massive contribution that whole, living foods confer on our ability to fight these pathogens.
