Tufts-affiliated researchers may become incriminated in violating research ethics guidelines. They carried out a study to test the efficacy of Golden Rice,  a genetically modified crop incorporating beta carotene, in providing the adequate needs of Vitamin A. The study involved 24 children whose ages ranged from 6-8 years in Hunan Province, China. The study acquired ethical approval from Tufts University IRB and Zhejiang Academy of Medical Sciences in China.

According to Greenpeace international, Golden Rice is not fit for human consumption and they are alleging that researchers failed to acquire informed consent from participants or the appropriate approval from the Chinese government.
