Farmers prepare to vaccinate pigs Thursday in Zhuji, East China's Zhejiang Province. The local government requires mandatory vaccines for livestock, and offers farmers a subsidy of 80 yuan ($13) for each dead pig they dispose of in an environmentally friendly way. Nearly 10,000 pig corpses have been found in the Huangpu River over the past week, and Jiaxing in Zhejiang is believed to be the source of the dead animals. Photo: CFP
