Scientific Opinion


This scientific opinion evaluates the risk assessment for the authorisation for (continued) marketing of genetically modified insect-resistant and herbicide-tolerant cotton MON 531 × MON 1445 for food and feed produced from it. Cotton MON 531 × MON 1445 was produced by conventional crossing methods, and the stack is homozygous for the newly introduced traits. The integrity and the stable co-inheritance of the parental events were demonstrated in the stack. Molecular characterisation did not reveal safety issues. No biologically relevant differences were identified in the compositional, phenotypic and agronomic characteristics of cotton MON 531 × MON 1445 in comparison with its conventional counterpart and its composition fell within the range of non-GM cotton varieties, except for the Cry1Ac, CP4 EPSPS and NPTII proteins. No safety issues were identified with regard to toxicity and allergenicity of food and feed produced from cotton MON 531 × MON 1445. A feeding study in catfish confirmed that toasted cottonseed meal from MON 531 × MON 1445 is as nutritious as toasted cottonseed meal from its conventional counterpart and four commercial non-GM cotton varieties. Products from cotton MON 531 × MON 1445 do not contain viable plant parts. The insert structure in cotton MON 531 × MON 1445 may facilitate the stabilisation of the nptII gene in plasmids of environmental bacteria through double homologous recombination. However, considering the overall limited occurrence of horizontal transfer of DNA in plant material to bacteria, and the very low exposure to DNA from cotton MON 531 × MON 1445, the EFSA GMO Panel concludes that it is highly unlikely that cotton MON 531 × MON 1445 will contribute to the environmental prevalence of nptII genes. Potential interactions of cotton MON 531 × MON 1445 with non-target organisms and the abiotic environment were not considered to be an issue because of low exposure levels. A post-market environmental monitoring plan is not required.
