In acute toxicity studies with male/female rats, which were tube-fed homogenized GM tomatoes, toxic effects were claimed to be absent. In addition, it was concluded that mean body and organ weights, weight gains, food consumption and clinical chemistry or blood parameters were not significantly different between GM-fed and control groups. However:
The unacceptably wide range of rat starting weights (±18% to ±23%) invalidated these findings.
No histology on the intestines was done even though stomach sections showed mild/moderate erosive/necrotic lesions in up to seven out of twenty female rats but none in the controls. However, these were considered to be of no importance, although in humans they could lead to life-endangering hemorrhage, particularly in the elderly who use aspirin to prevent thrombosis.
Seven out of forty rats on GM tomatoes died within two weeks for unstated reasons.
These studies were poorly designed and therefore the conclusion that FLAVR SAVRTM tomatoes were safe does not rest on good science, questioning the validity of the FDA’s decision that no toxicological testing of other GM foods will in future be required.
GM maize: Two lines of Chardon LL herbicide-resistant GM maize expressing the gene of Phosphinothricin Acetyltransferase Enzyme (PAT-PROTEIN) before and after ensiling showed significant differences in fat and carbohydrate contents compared with non-GM maize and were therefore substantially different. Toxicity tests were only performed with the PAT-PROTEIN even though with this the unpredictable effects of the gene transfer or the vector or gene insertion could not be demonstrated or excluded. The design of these experiments was also flawed because:
The starting weight of the rats varied by more than ±20% and individual feed intakes were not monitored.
Feed conversion efficiency on PAT-PROTEIN was significantly reduced.
Urine output increased and several clinical parameters were also different.
The weight and histology of the digestive tract (and pancreas) was not measured.
Thus, GM maize expressing PAT-PROTEIN may present unacceptable health risks.
Эти тесты еще хуже, чем те, которые клеймил ты
Но им, почему-то. ты говото поверить
