A young couple took their teats to the streets of downtown Xi'an, Shaanxi Province, selling milk squeezed fresh to order from four goats, according to China News Service. Though the clever curbside service on July 8 drew both crowds and cash, experts voiced concerns over food safety issues. Sun Chengzhi, Director of nutrition at Dalian Health Check Center, told Peninsula Morning Post that the vendors should have been approved by health authorities and maintain proper hygiene while milking. Sun Lidan, the director of respiratory medicine at Dalian Friendship Hospital, warned of the dangers of spreading Brucellosis, an bacteria that transmits from animals to people, often through unpasteurized milk, that causes high fever and convulsions.
