Vienna – Feeding mice with genetically engineered maize developed by the US-based Monsanto corporation led to lower fertility and body weight, according to a study conducted by the University of Veterinary Medicine in Vienna presented Tuesday. In the study, mice fed with the NK603 x MON810 sweetcorn variety over a period of 20 weeks showed a smaller litter size and lighter offspring than mice fed with non-engineered maize.
The differences “were statistically significant in the third and fourth litters,” according to an abstract of the study led by Professor Juergen Zentek and commissioned by Austria’s Environment Ministry.
Although in an alternative set-up of the study the differences between the groups of mice were found to be less pronounced and statistically not significant, the environmental organization Global 2000 said this meant that further long-term tests were needed.

Austria has long resisted calls by the European Commission to allow the use of genetically modified food, but it finally had to lift its ban on MON810 maize as animal feed last year.
However, Austrian feed companies have so far agreed to a self- imposed ban on MON810.
