Why is milk pasteurized?
In the 1800s, many US dairies began commercially producing low quality raw milk in the inner cities of Boston and New York and others. These Brewery dairies would feed their cows very poor quality “brewer’s mash.” The resulting milk was very weak and nearly blue from lack of protein, mineral, and fat content. This occurred during the Jamaican rum embargo. During this same time period, the dairy industry did not use or have access to refrigeration, stainless steel, milking machines, rubber hoses, hot water, or chlorine as a sanitizer.

The cows stood in manure and there was no access to pasture (sounds like some factory dairy farms of 2005). The resulting unhealthy milk from these sources literally killed millions. The heating of milk to high temperatures reduced this horrible blight. During this same t
