Gloeckner continued to lose cows and many more had to be put down due to serious illnesses, compelling him to stop using GM feed from 2002. He approached the Robert Koch Institute and Syngenta to conduct a full investigation. However, only one cow was ever analysed and the data are still unavailable to the public. Unsurprisingly, no causal relationship between the GM feed and deaths was determined; and there is still no explanation for the deaths.
But in 2009, the farmer learned of a feeding study allegedly commissioned by Syngenta in 1996 that resulted in four cows dying in two days. The trial was abruptly terminated. Now Gloeckner, along with a German group called Bündnis Aktion Gen-Klage and another farmer turned activist Urs Hans, have brought Syngenta to the criminal court to face charges of withholding knowledge of the US trial, which makes the company liable for the destruction of the farmer’s 65 cows. Syngenta is also charged with the deaths of cattle in the US trial and on Gloeckner’s farm, which should have been registered as “unexpected occurrences”. Most seriously, the German head of Syngenta Hans-Theo Jahmann, is charged for withholding knowledge of the US study from the judge and from Gloecker in the original civil court case.
