Local inhabitants of Mustang district of Nepal drink fresh raw blood from Yak (Bos grunniens) because they think the blood has healing properties in addition to providing strength to the human body. Beyond the "blood drinking" practices in the high hills of Nepal, there lies an unknown health hazard. The hypothesis of this project: The blood of yak in Himalayas of Nepal contain microbes which can potentially harm the drinkers of yak's raw blood.
