“While the use of the word ‘pus’ is admittedly pejorative, it is nonetheless an appropriate word. To say ‘white blood cells’ would not convey the emotional – nor the holistic – totality of the real situation. In reality, hormone treated cows, in confined spaces, over-bred for production, denied fresh grass and over-milked, are going to be stressed and are going to have far higher rates of mastitis [infected teats] than well-cared for cows (and goats) at an organic dairy devoted to raw milk – and this WILL mean far higher counts of inflammatory cells and inflammation products in the milk – ‘pus’…

I have no trust at all in arguments from the pasteurized milk side of the debate; defending their side on the basis that all milk contains ‘some’ white blood cells and therefore the word ‘pus’ should not be used… Modest amounts of white blood cells normally found in clean, healthy milk (which are there because the faithful little helpers get EVERYWHERE looking for germs), is not the same as inflammatory cells and inflammatory products from inflamed teats and udders.”
