Dairy Goats Cleared in Poison Oak Study

Anyone who has ever contracted the terrible rash associated with poison oak will have a profound appreciation for the adage Leaves of Three, Don't Touch Me. To avoid exposing workers during the removal of poison oak, goats are being used increasingly as a chemical-free way to eradicate poison oak. While goats have proven to be efficient and economical in removing the troublesome brush, some people expressed concern that the irritating toxic chemicals found in poison oak, called uroshoils, might be entering the milk of dairy goats and posing a health threat to consumers of dairy goat products. In a recent study conducted at the UC Davis Dairy Goat Facility, a team of UC researchers found otherwise. They fed varying amounts of poison oak foliage to dairy goats. No uroshoils were found in the milk, indicating that farmers using dairy goats to clear poison oak need not worry about contaminating the goats' milk. The results of the study are reported in the current issue of California Agriculture, a research magazine published by the UC Division of Agriculture and Natural Resources.
