Jeffrey W. Hull, MD, FAAP, practicing pediatrician, provided the following response to the question "Do you feel that it is accurate to state that there is indeed pus in milk?" in a Jan. 4, 2008 email to

“No. Pus contains much more than simply white cells. There are dead neutrophils present, live nutrophils, dead tissue cells, blood proteins, dead and sometimes live bacteria…Pus is a pejorative and prejudicial term in this context, especially for material aimed at the scientifically naive. White cells – both neutrophils but also immunity bearing lymphocytes – are present in all mammalian milks. They have no bearing on the health of the beverage. Only bacterial or mycobacterial contamination of milk is of any relevance in my view.”
