France checks the scientific validity of shocking GM food study

French Prime Minister Jean-Marc Ayrault says he is prepared to call for a wider European ban on genetically modified produce following an alarming new study that throws the safety of the food into doubt. The report claimed that 200 rats fed GM corn produced by US firm Monsanto had suffered tumours as big as ping-pong balls. Ayrault has ordered that the scientific validity of the study be checked by the country’s health watchdog. So far Monsanto has not responded to the findings.
