You might want to think twice about food shopping at Walmart before the next family barbecue. The store has admitted it will start selling genetically engineered sweet corn – the first such sweet corn to be widely available as a whole, unprocessed food on American supermarket shelves.

The sweet corn has been genetically engineered to withstand large amounts of Roundup weed-killer and also to produce a pesticide, Bt toxin, within the corn itself. Yum, a little butter and salt with that?

This is the first time Monsanto has engineered a vegetable that could be served straight to your dinner table. Its health impacts on humans are largely unknown - but if this unlabeled and potentially dangerous products succeeds, Monsanto is sure to bring us even more. Even worse, if the product is successful at Walmart, even more grocery chains may start selling unlabeled GMO produce directly to consumers.

In light of this information, what’s a consumer to do? How can we tell if the sweet corn on our barbecue is genetically engineered?

We can’t, until we get labeling.

Please sign and share widely. Help us give consumers a choice about purchasing potentially dangerous GMOs, and stop the sale of unlabeled Bt toxin sweet corn at Walmarts and other grocery stores across the country.
