Maize 1507: The crop of European fear and indecision

By Nick Dinan

Most of us know that maize is one of the four staple crops for human nutrition, rice, wheat and potatoes being the others. Considering global food insecurity, in what ways could we make this crop better? Perhaps the more urgent question is how have betterments to the crop been restricted, particularly within the ever-skeptical European Union.

1507 maize is a genetically modified version of maize produced by Pioneer DuPont with the aim of being cultivated within the EU. This variety of transgenic maize has the ability to produce an insecticide (Bt-toxin), derived from genes of the bacterium Bacillus thuringiensis. 1507 maize is protected from pests such as the European corn borer – caterpillars of this species chew tunnels that compromise the structural integrity of Maize, destroying it in the process.

The crop was first presented in Spain in 2001. However, a chain of bureaucratic constraints, with repeated drafts of proposals for the crop being delayed due to the indecision of the European Commission, has delayed 1507 maize’s entry into the European market for 12 years. Ever most concerning is that 1507 maize meets all of the European Union’s regulatory requirements for genetically modified crops, such as safety compared to the original crop.

Reservations about 1507 maize are clear – can we ingest a toxin that has the capacity to kill insects? Maize is one of our staple crops; won’t the over-consumption of such a toxin have long-term adverse effects on our health? Who would want to feed their child toxic corn? Copious amounts of research refute these reservations.

The proteins expressed in 1507 maize (Cry1F & Pat) that produce the Bt toxin are not toxic or allergenic to humans and animals. You might say we’re unsure of the long-term effects of the Bt toxin – how do we not know that there isn’t a network of dangerous pathways the toxin may ignite? Quite simply, there isn’t – creation of 1507 maize is not intertwined with the application of the Bt toxin. In fact, Bt sprays have had a history of controlling insect pests by spraying since the 1920s, where it is universally understood to be safe due to the specificity of the chemical for pests. Furthermore, 1507 maize and maize have nutritional equivalency, as well as identical risks of hybridization with wild populations (very low) and levels of environmental impact. It did not take 12 years to discover these facts; in 2005 the GMO Scientific Panel of the European Food Safety Authority (EFSA) concluded 1507 Maize to be just as safe as ordinary maize.

Only on the 6th of November did the European Commission approve cultivation of the crop. The concerns of a GM-conservative government and populace was embodied in protests from environmental groups about safety, despite frustratingly manifest evidence that should have silenced their qualms.

This is the third GM crop to be approved for cultivation in the European Union. We could perceive this as a victory, but ultimately this huge delay represents the unwarranted skepticism of the developed world towards GM crops. Perhaps we don’t have the same degree of urgency, eradicated by the luxury of huge choice in what we eat. The organic, “gene-less” tide may be okay for now, but we’re at the risk of creating a culture not based on efficient cultivation that will be required in the future.
