"Regarding one of the medicines, one of the laboratories confirmed the presence of DNA of human species, but the other laboratory has not confirmed the same. Regarding the other medicine, neither of the laboratories found DNA of any human origin," he said adding, a third sample was confirmed containing animal organ.

"We have sent reports to the Uttaranchal government and also further information sought by them. The state government is the competent authority to enquire into the matter further and take necessary action," he said in reply to a series of questions on the matter.

The CPI(M) member had submitted two samples of medicines for epilepsy and virility on which several tests, including DNA, were conducted by reputed national laboratories in Hyderabad, Chennai and Kolkata, he said.
