OGM Maize cause tumours in rongeurs

A report out yesterday showed that rats fed  OGM ( genetically modified ) maize, spelt mais  in French and prounced like mice, get mammary tumours quite quickly. Roundup the weedkiller had very similar effects on the rats. I was reading this report in the Depeche when the same report came on France 2 Tele Matin. Ronguers are rats, mice anything that gnaws.
