I raised 4 kids on raw milk and never had any problems. Yeah, there's parasites in milk or any raw food. If you ever watch a toddler all day you realize it's a wonder any of us survive to adulthood with all the germs we ingest. You can't and shouldn't sterilize everything.
When my son started drinking pasturized milk he developed seasonal allergies and hayfever. Once I convinced him to give up his pasturized milk he was astonished to find his allergies completely cured.
