China tainted milk 2011 5 3

A woman pushes a pram carrying a carton of Japanese milk powder outside a store in the Kowloon district of Hong Kong on March 16, 2011. Hong Kong residents have been bulk buying the preferred Japanese milk powder amid concerns that dangerous radiation seeping from stricken Japanese nuclear power plants could affect or contaminate further imports. Meanwhile Hong Kong has widened its top-level black travel alert to three more Japanese prefectures after explosions at a nuclear plant.
