Mais estudos demontram que animais alimentados com dietas OGM enfrentam distúrbios hepáticos e renais

A new report reviewing 19 studies of mammals fed with commercialized GM soybean and maize which account for more than 80% of all GMOs grown on a large scale appears to indicate liver and kidney problems in the mammals fed on the GMO diet.

The report by Gilles-Eric Seralini et al is published in Environmental Sciences Europe. The authors studied raw data of 90-day-long rat tests that include biochemical blood and urine parameters of mammals eating GMOs modified for pest resistance. The tests were conducted as a result of court actions or official requests and the authors reviewed the studies in the light of modern scientific knowledge.

Though the tests may not point to chronic toxicity of GMOs the authors nonetheless cautioned that the signs highlighted in the kidneys and livers could spell the onset of chronic diseases and suggested that more detailed and prolonged studies be conducted. The authors stated that since no minimal length for the tests is yet obligatory by European law for any of the GMOs cultivated on a large scale this is socially unacceptable in terms of consumer health.

The authors also suggested an alternative to conventional feeding trials, to understand the biological significance of statistical differences. This approach will make it possible to avoid both false negative and false positive results in order to improve safety assessments of agricultural GMOs before their commercialization for cultivation and food/feed use and imports.
