Pus In Milk

So, at work today I heard a guy talking about the pus in milk. I had no idea what he was talking about so of course I googled it. Apparently milk isn't the only thing that you're drinking after you pour yourself a glass of milk...

 A dairy cow filters ten-thousand
quarts of blood through her udder each day and
uses dead white blood cells (somatic cells) to
manufacture her milk. These dead cells are pus
cells. Dairy scientists are aware that when
one quart of milk is tainted with 400 million
or more pus cells, some 35% of the milking
cows in the herd are infected with mastitis.
Udders bleed, discharges, including bacteria and blood drip into the milk.

 Disgusting right? I thought so too. Check out the chart below. Yeah, it's a little outdated (2001), but still...

(The following list contains the number of pus cells
expressed per milliliter of milk... about the size of a
thimbleful. To obtain the number of pus cells per LITER of
milk [about one quart] please add three zeros to the
following numbers)
