Pedersen, who produces 13,000 pigs a year and supplies Europe's largest pork company Danish Crown, says he became so alarmed at the apparent levels of deformity, sickness, deaths, and poor productivity he was witnessing in his animals that he decided to experiment by changing their diet from GM to non-GM feed.
The results, he says, were remarkable: "When using GM feed I saw symptoms of bloat, stomach ulcers, high rates of diarrhoea, pigs born with the deformities ... but when I switched [to non GM feed] these problems went away, some within a matter of days."
Pedersen claims that independent testing revealed all of his deformed pigs had glyphosate in their organs. He shows me a chart he suggests shows a clear correlation between the volume of glyphosate found in pig feed and higher numbers of cranial and spinal deformities. "The more glyphosate, the more deformities," he says, bluntly.
