Okay, I hate to rain on everyone’s raw-milk parade here, but…
First and foremost, I was extremely disappointed by this video - and this is coming from someone who’s sympathetic to the natural-food camp. But IMO the video was very short on substantive criticism and very long on unsubstantiated rhetoric. In all honesty, it seems to me like Mike Adams and the rest of the crew at Natural News think their readers are idiots, based on the content of this video.
Secondly, I think it’s intellectually dishonest to refer to leukocytes (white blood cells) as “pus”. Yes, they’re present in pus (dead), but they’re also present throughout the body. Natural News might as well produce a video telling us repeatedly that we’re nothing but a bunch of walking pus-sacks.
Thirdly, I made some back-of-the-envelope calculations to find out just how much of a milliliter (mL) of milk would consist of leukocytes, in terms of both volume and mass. Based on this link, I used a cell radius of 10 micrometers, which is a conservative estimate (I can’t imagine bovine leukocytes being very different from human leukocytes). 750,000 of such cells would comprise a total volume of about 3.1415927 * 10^9 cubic micrometers. One milliliter is equal to one cubic decimeter, which is equal to 0.001 cubic meters, which is equal to 1.0 * 10^-15 cubic micrometers. The total fraction of one milliliter of milk taken up by these 750,000 cells would then be 0.0031415927, or 0.31415927%.
For mass, since cells are about as dense as water (1 g/mL), I used a leukocyte mass of 4.18879 * 10^-9 grams. 750,000 of the somatic cells would then collectively mass about 0.0031415925 grams. From here I used a density of milk of 1.027 g/mL (1 kg/L is the same as 1 g/mL). The total fraction of the mass of one milliliter of milk taken up by these 750,000 cells would then be 0.0030589995, or 0.30589995%.
So there you have it. Even at the maximum allowable level, less than 1% of milk, in terms of both volume and mass, would be taken up by somatic cells. I wouldn’t exactly call that drinking pus. That doesn’t even go into the fact that the somatic cell count is typically taken before the milk is processed. The pasteurization process would presumably kill all the leukocytes, if they weren’t dead already after milking.
