Ecuador accused US scientists on June 16 of taking thousands of unauthorised blood samples from indigenous Huaorani and selling them.
The Huaorani are known for a unique genetic profile and disease immunity and the samples are believed to have been sold by the Coriell Institute for Medical Research to Harvard University Medical School.
Ecuador鈥檚 constitution bans the use of genetic material and scientific research in violation of human rights.
There were about 鈥3500 procedures鈥 in which blood was drawn without authorisation from 600 Huaorani, who live in Ecuador鈥檚 Amazon basin region, said Higher Education and Science Ministry chief Rene Ramirez.
Samples 鈥渨ere taken on more than one occasion鈥, he said while revealing details of a new government investigation.
In an initial investigation two years ago, the Huaorani said US scientists duped them between 1990 and 1991. They were told the blood samples were for medical tests, but the results never materialised.
鈥淚t was demonstrated that the Coriell Institute has in its stores samples [from the Huaorani] and that it sells genetic material from the Huaorani people,鈥 the report said.
President Rafael Correa said there was information indicating that samples had been taken as far back as the 1970s 鈥渋n complicity with the oil company operating in the area鈥.
Correa said the blood was being used in research. He said there was 鈥渘o US federal legal grounds to sue鈥 but he would look for other litigation options.
