GM fears revived

The scientific establishment, including the European food safety authority, has rounded on a study published in September that appeared to show that feeding rats a popular genetically-modified (GM) corn gave them cancer (see PN 2550).

Critics have complained, for example, that too few rats were used in the trial – 50 of each sex is the norm for cancer studies. 

Professor Gilles-Eric Seralini, of Cannes University, has explained that he used only 10 of each sex because he was not expecting cancer to occur, as no previous GM food study had indicated such a risk.
