Initial research indicates dairy goats used to clear poison oak do not transfer toxicant to milk

Abstract

Dairy goats that eat poison oak do not transfer detectible amounts of the toxic principle, urushiol, to the milk or to the urine. Furthermore, this oily, toxic irritant is found in goat manure at less than 9% of its concentration in poison oak leaves. What does all this portend? That farmers using dairy goats to clear poison oak need not worry about contaminating the goats' milk with urushiol. More studies are underway.
