In 1995, Pusztai began research on genetically modified potatoes containing the GNA lectin gene from the snowdrop plant.[1] His research team fed raw and cooked genetically modified potatoes to rats, using Desiree Red potatoes as controls. In 1998, Pusztai said in an interview on a World in Action programme that his group had observed damage to the intestines and immune systems of rats fed the genetically modified potatoes. He also said, "If I had the choice, I would certainly not eat it," and "I find it's very unfair to use our fellow citizens as guinea pigs."[2]
