The State Food and Drug Administration (SFDA) is investigating an allegation by Nigeria that a consignment of drugs labeled 'Made in India' were, in fact, fake pharmaceuticals produced in China, said SFDA spokesperson Yan Jiangying.

The Times of India reported this week that the forged anti-malaria pharmaceuticals were "a large consignment" and that they were seized by the Drug Regulatory Authority (NAFDAC) of Nigeria.

Had the drugs not been intercepted, about 642,000 adults would likely have taken the potentially harmful product, said NAFDAC.
