Abstract

This scientific opinion reports on a risk assessment for the authorisation for (continued) marketing of genetically modified maize T25 for food and feed uses, import and processing. Maize T25 contains a single insertion locus containing a pat cassette conferring tolerance to glufosinate-based herbicides. Bioinformatic analyses, protein expression data and genetic stability studies did not raise safety issues. The compositional, agronomic and phenotypic characteristics of maize T25 grain and its conventional counterpart showed no differences that are of relevance for food/feed safety. The safety assessment identified no concerns regarding the potential toxicity and allergenicity of the newly introduced PAT protein. The compositional data indicating the nutritional equivalence of maize T25 were supported by the results of the feeding studies. There was no evidence that the genetic modification might significantly change the overall allergenicity of maize T25. Considering all available information related to the agronomic and phenotypic characterisation of maize T25, the EFSA GMO Panel did not observe any enhanced fitness characteristics of maize T25 that will change its capacity to spread, establish or persist compared with non-genetically modified (GM) maize, except in the presence of glufosinate-based herbicides. Considering its intended uses as food and feed, interactions with the biotic and abiotic environment were not considered an issue. Risks associated with an unlikely but theoretically possible horizontal gene transfer from maize T25 to bacteria have not been identified. The monitoring plan and reporting intervals were in line with the intended uses. The Panel concluded that maize T25, as described in the applications, is as safe as its conventional counterpart with respect to potential effects on human and animal health or the environment in the context of its intended uses for food and feed, import and processing

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
