China’s melamine-tainted milk scandal is increasingly global in its impact, as Cadbury PLC became the latest company to announce a recall amid concerns that chocolate from its Chinese plant may be contaminated with melamine. Cadbury recalled all products made in its Beijing plant, which were distributed throughout mainland China, Australia, Taiwan and Hong Kong. Although government tests did not detect the chemical in their milk products, the company said they took this precautionary step because of questionable results of additional testing.
