More than 110 people have been arrested in China for selling pork from diseased animals. The Public Security Ministry said more than 1,000 tons of contaminated pork and 48 tons of cooking oil produced from the meat have been seized across 11 provinces. The investigation reportedly began at the end of 2013 into producers who have been buying pigs that died from diseases at low prices for years with the help of government livestock insurance agents. The ministry said that the seized products were valued at more than 100 million yuan ($16 million) and that 75 suspects have already been prosecuted. China is no stranger to food scandals. In January 2014, the Chinese branch of Walmart super stores issued a recall of donkey meat products after some of it was found to contain fox DNA. In 2013, more than 10,000 dead pigs were found floating down a river in Shanghai that supplies tap water to the eastern Chinese city.
