Opinion of the Scientific Committee/Scientific Panel

This scientific opinion reports an evaluation of a risk assessment for placing on the market of insect resistant genetically modified (GM) cotton (Gossypium hirsutum L.) 281-24-236 x 3006-210-23 (Unique Identifier DAS-24236-5 x DAS-21Ø23-5) for food and feed uses, import and processing. The GM cotton 281-24-236 x 3006-210-23 has been produced by conventional crossing between lines of the single cotton events 281-24-236 and 3006-210-23. The cotton 281-24-236 x 3006-210-23 expresses combined traits encoded by cry1F in event 281-24-236 and by cry1Ac in event 3006-210-23, both genes conferring resistance to certain lepidopteran pests. Both single events contain pat genes used as a selectable marker. The structure of the inserts in the single cotton events was retained in the stack 281-24-236 x 3006-210-23. Expression levels of Cry1Ac, Cry1F and PAT proteins were demonstrated to be comparable to those of the respective single events. The results of comparative analyses indicated that cotton 281-24-236 x 3006-210-23 and its respective single events are compositionally, agronomically and phenotypically equivalent to its conventional counterpart, except for the expression of Cry1Ac, Cry1F and PAT proteins. The safety assessment identified no concerns regarding toxicity and allergenicity of cotton 281-24-236 x 3006-210-23. A feeding study on broiler chickens confirmed the nutritional equivalence of this GM cotton to its conventional counterpart and two commercial non-GM cotton varieties. The intended uses of cotton 281-24-236 x 3006-210-23 exclude cultivation within the European Union. The environmental risk assessment is therefore restricted to the indirect exposure through manure and faeces mainly from animals fed with cotton products of 281-24-236 x 3006-210-23 and with the accidental release into the environment of cotton 281-24-236 x 3006-210-23 grains during transportation and processing. There are no indications of increased likelihood of establishment or survival of feral cotton plants. If accidental spillage and subsequent release into the environment of cotton 281-24-236 x 3006-210-23 seeds occur, cotton 281-24-236 x 3006-210-23 plants would have a selective advantage only under infestation of target pest species or in presence of glufosinate-ammonium herbicides, which are not commonly used on cultivated cotton or in most areas where the GM cotton might be spilled. In conclusion, the EFSA GMO Panel considers that information available for cotton 281-24-236 x 3006-210-23 addresses the scientific comments raised by Member States and that the cotton 281-24-236 x 3006-210-23 as described in this application is as safe as its conventional counterpart and other appropriate comparators with respect to potential effects on human and animal health and the environment in the context of its intended uses. The EFSA GMO Panel concludes that cotton 281-24-236 x 3006-210-23 is unlikely to have any adverse effect on human and animal health and the environment, in the context of its intended uses.
