As known from other casessuch as MON810 (a genetically engineered maize expressing Cry1Ab Bt toxin), independent research [71] has shown that the data provided by industry do not show the true range of variation of Bt toxins in the plants. soybeans naturally contain many allergens, these immunogenic properties raise specific questions. (3) Fully evaluated and reliable protocols for measuring the Bt concentration in the plants are needed, in addition to a comprehensive set of data on gene expression under varying environmental conditions. (4) Specific attention should be paid to the herbicide residues and their conversation with Bt toxins. Conclusions The case of the soybeans highlights several regulatory problems with Bt soybean plants in Rabbit Polyclonal to MAP4K3 the EU. Moreover, many of the issues raised also concern other genetically engineered plants that express insecticidal proteins, or are engineered to be resistant to herbicides, or have those two types of traits combined in stacked events. It remains a matter of debate whether the standards currently applied by the risk assessor, EFSA, and the risk manager, the EU Commission, meet the standards for risk analysis defined in EU regulations such as 1829/2003 and Directive 2001/18. While this publication cannot provide a final conclusion, it allows the development of some robust hypotheses that should be investigated further before such plants can be considered to be safe for health and the environment. In general, the concept of comparative risk assessment needs some major revision. Priority Bupranolol should be Bupranolol given to developing more targeted approaches. As shown in the case of these approaches should include: (i) systematic investigation of interactions between the herb genome Bupranolol and environmental stressors as well as their impact on gene expression and plant composition; (ii) detailed investigations of the toxicity of Bupranolol Bt toxins; (iii) assessment of combinatorial effects taking into account long-term effects and the residues from spraying with complementary herbicides; (iv) investigation into the impact on the immune and hormonal systems and (v) investigation of the impact on the intestinal microbiome after consumption. Further and in general, stacked events displaying a high degree of complexity due to possible interactions should not undergo a lower level of risk assessment than the parental plants. was authorised for import and use in food and feed in the EU [1]. The soybeans combine the expression of an insecticidal Bt toxin, Cry1Ac, present in the parental event MON87701, with herbicide resistance to glyphosate from parental event MON89788. While Bt toxins are expressed in several genetically engineered maize and cotton herb events, MON87701 and its stack MON87701??MON89788 are the first Bt soybean varieties cultivated in countries, such as Brazil and Argentina, to be given authorisation for import into the EU. This review discusses some specific health risks posed by the genetically engineered soybeans and the risk assessment undertaken by the European Food Safety Authority based on the data from the company Monsanto, which carried out field trials in the US and Argentina [1]. Monsanto, however, did not investigate any combinatorial health effects emerging from Bupranolol the stacked trait. The data provided by the applicant concern acute toxicity testing with a high dosage of the isolated Bt toxin in mice [2]. In addition, they provided two 90-day studies with meal derived from MON87701; the data from these studies showed a range of uncertainties, such as significant changes in body weight [2]. Monsanto also provided data on allergenicity [1, 2]. Some of the findings are discussed in the relevant passages below. We elaborate on potential health impacts due to toxic, immunogenic or combinatorial effects involving the Bt toxins, and on the residues from spraying with the complementary herbicide. As yet, there has not been a fully comprehensive review of possible health impacts due to Bt toxins expressed in genetically engineered plants in conversation with constituents from soybeans that, in addition, are resistant (used herein as a synonym for tolerant) to glyphosate or.
