The latest food safety scandal in China might be its most damaging. A former doctoral student at one of the country's national testing centers for genetically modified organisms went public with allegations of scientific fraud, including claims that records were doctored extensively, that unqualified personnel were employed under illegal contracts and -- most seriously -- that authorities refused to take action when his concerns were aired privately. China's Ministry of Agriculture responded to a social media storm by suspending operations at the center. That might take care of the current scandal, but the Chinese public's hostility toward GMOs won't go away so easily. Those concerns have only grown over the past decade as the government has increased its support of GMOs, including approval of the state-owned ChinaChem Group's $43 billion takeover offer for the Swiss seed giant Syngenta.
