On 11 September 2012, the Science Media Centre published response comments (by Prof. Rick Roush, Assoc. Prof. Peter Dearden, Prof. Peter Langridge and Dr. Ian Edwards) in reply to expert scientific opinions about the safety of GM wheat varieties that have been developed by the Commonwealth Scientific and Industrial Research Organisation of Australia. [...] After reviewing the response comments, ENSSER is disappointed by the Science Media Centre's decision to post personal attacks by the commentators on the authors of the original reports, rather than engage in a scientific debate that might have been useful to journalists, its stated audience.
