Most cows suffer mastitis due to their unusually large udders. This disease not only harms the animals, it also harms anyone who attempts to live off their milk. The average glass of milk contains seven drops of pus! Antibiotics are a part of the feed of these cows and are intended to prevent a fulminating infection. These drugs are also excreted in their milk along with large quantities of dioxins since there is no regulation on pesticides for animal feed.
