Processing of the case in Central Hesse shows the interaction of other unfavorable factors
Feeding the genetically modified, insect-resistant Bt-176 maize from Syngenta is not responsible for the health problems of dairy cows on a farm in Central Hesse. The scientific processing, analysis and final evaluation of possible causes was completed in January 2003. In the conclusion of this causal research, independent experts and the responsible Robert Koch Institute (RKI) in Berlin come to the conclusion that an interaction of several unfavorable, health-damaging factors, but not Bt-176 maize, caused the deaths.
Syngenta regrets the events and problems on the farmer's farm. That's why the company helped him find the triggering factors. Syngenta's support was provided on the one hand in the form of examinations and analyzes as well as the involvement of recognized experts. On the other hand, Syngenta also supported the farmer financially in the situation that threatened his existence, in order to help him out until the causes were clarified. This clarification was completed for the company with the receipt of the final report from the RKI.
After the experts consulted had attested deficiencies in feeding and hygiene, the farmer expressed the hypothesis in December 2001 that the Bt maize could possibly be related to the problems. In April 2002, Syngenta arranged for an official sample to be taken, in which not only the Bt maize but also the other components of the feed ration were sampled.
The experts consulted name a mixture of high infectious microbial pressure, harmful concentrations of fungal toxins in the feed, excess protein in the animals, feeding of unsatisfactory quality grass silage and significant feeding errors as the causative factors for the disease and death of the cows. In addition, the animals have been exposed to frequent feed changes in rapid succession, which is a problem for the digestive tract and the health of ruminants. At the suggestion of Syngenta, an examination of the population for botulism, a bacterial poisoning, was carried out in 2002. The toxic pathogen itself could be detected in dead animals or antibodies in living animals. Despite these serious results, the farmer declined advice from an independent feeding expert and refused to take further samples.
Syngenta emphasizes that scientific evidence and recognized experts rule out Bt maize from any association with the problems encountered on the farm.
1. The BT-176 maize fed in the central Hessian company is approved as animal feed in Germany, so it passed the safety tests of the approval process with positive results. In Spain, maize has been grown on an area of around 20.000 hectares for years. There have also been positive experiences from the USA, although Syngenta is now marketing an even more successful successor product there.
2. In its final report, the responsible approval authority, the Robert Koch Institute, came to the conclusion that the suspicion of a connection between the deaths and the feeding of Bt-176 maize could not be substantiated.
Theo Jachmann, Managing Director of Syngenta Germany: "Syngenta has worked closely with the farmer and consulted recognized experts to solve the problem. Several factors such as botulism, a very serious bacterial poisoning, came to light. All of them Those involved should not ignore the problems that actually exist and are clearly identified by the experts, otherwise they not only damage a new future technology, but also endanger consumers.
