GMO potatoes: The risks to health

Dr Caius Rommens developed GMO potatoes, but subsequently renounced his work. He explains why we should be wary of the products he created

Dr Caius Rommens developed GMO potatoes for the Idaho-based agbiotech company Simplot. The chief genetic modification he introduced was to silence the potatoes’ melanin (PPO) gene. This gene, when operative, causes potatoes to discolour when bruised. The GMO potatoes do not discolour when bruised. They have therefore been marketed as bruise-resistant and are being sold without GMO labels in the US under innocuous-sounding names like Innate, Hibernate, and White Russet. They’ve also been approved in Canada but are not yet being sold there, according to research by CBAN.

After finding that “most GMO varieties were stunted, chlorotic, mutated, or sterile, and many of them died quickly, like prematurely-born babies”, Dr Rommens renounced his genetic engineering career and wrote a book about his experiences, Pandora’s Potatoes: The Worst GMOs, which is available from Amazon.

In an interview with GMWatch, Dr Rommens discussed the risks to health posed by the GMO potatoes he created.
