New Séralini study shows Roundup damages sperm

Professor Gilles-Eric Séralini is a French scientist researching pesticides and GM (genetically modified, genetically engineered, GE) crops. He’s published a new study in which rats (Rattus norvegicus) were exposed to the world’s most popular weedkiller, Roundup (active ingredient glyphosate) for eight days. It was bad news for their sperm, not so much during those eight days but for months afterwards.

Claire Robinson*, Managing Editor of GMO Seralini, explains the new study. This was ‘the first [study] to measure the delayed effects of exposure to Roundup on sperm in mammals from a short exposure…

‘The study’s findings should raise alarm in farm workers, as well as people who spray Roundup for municipal authorities and even home gardeners. People exposed to lower doses repeated over the long term, including consumers who eat food produced with Roundup and people who happen to be exposed to others’ spraying activities, should also be concerned.’

Here’s the new science.

In case you’d like a reminder, here’s my blog post about how Roundup and Roundup Ready crops work.

You might also want to look at the series of blog posts in which I comment on Prof Séralini’s most famous (or infamous) previous study. That study was a feeding trial in which rats ate a GM maize (corn, Zea mays) called NK603 from Monsanto and the Roundup which NK603 had been engineered to resist.

Here in Britain, and no doubt in other countries too, cute Roundup adverts appear on our television screens. Roundup is easy to buy with our groceries and gardening supplies. Doesn’t it look easy to spray a little weedkiller? As I continue my series about Prof Séralini’s rat-feeding trial, please remember that Roundup is poison.

* Claire Robinson is also one of the leaders at Earth Open Source.

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.

  1. Heard reports that Roundup’s ingredients, combined with glyphosate, make it many times more harmful than its active ingredient glyphosate alone. Drench your farm crops/food with poison in an acceptable practice to save the work of weed pulling. Drench your lawn with poison to avoid looking at dandelions. Then poison your body with chemo to get rid of the Roundup caused cancer. Perfect sense.
