On the surface of it, his now-controversial research was perfectly straightforward: he fed genetically modified potatoes expressing a snowdrop lectin to rats and looked to see whether this food affected their physiology, particularly the gut, metabolic process and immune system.
Pusztai had mentioned two lines of genetically modified potatoes, meaning the two GNA lines, and this was reported by the media. The Rowett institute mistakenly assumed the media was talking about a second line transformed with concanavalin A (ConA), a Jack Bean lectin that is toxic to mammals.
Oct 16, 1999 · In response to Stanley Ewen and Arpad Pusztai's letter on the health risks of genetically modified foods (Aug 21, p 684),1 we would like to clarify several points about the methodology of our review of data on the possible toxicity of genetically modified (GM) potatoes.

Apr 17, 1999 · Arpad Pusztai, a biochemist who used to work at the Rowett Research Institute in Scotland, said he had shown that GM potatoes were harmful to rats because of their genetic modification alone.
May 5, 1999 · Thus expression of this lectin in food plants might render them unattractive to insects but safe for human consumption, particularly if the food (potato) is always cooked before ingestion. Pusztai’s experiments, whatever their results, would not show that all genetically modified foods were unsafe.

Oct 22, 1999 · The study made headlines around the world in August 1998, when Pusztai, a scientist at the Rowett Research Institute in Aberdeen, announced in a television interview that a diet of genetically modified (GM) potatoes could stunt rats' growth and impair their immune system.
