BEIJING (Reuters) - China has ordered the world's top pork producer, WH Group Ltd <0288.HK>, to shut a major slaughterhouse as authorities race to stop the spread of deadly African swine fever (ASF) after a second outbreak in the planet's biggest hog herd in two weeks.
The discovery of infected pigs in Zhengzhou city, in central Henan province, about 1,000 km (625 miles) from the first case ever reported in China, pushed pig prices lower on Friday and stirred animal health experts' fears of fresh outbreaks - as well as food safety concerns among the public.
