“Son of Séralini” – Monsanto’s response to his latest PR stunt

By Brandon Mitchener

Three years ago, Prof. Gilles-Eric Séralini shocked the world with a PR campaign alleging that feeding lab rats genetically modified (GM) maize and water laced with herbicide lead to the development of terrible tumors. His research was later retracted by the same scientific journal that had published, only to be republished a year later in a lesser journal. We have reacted to that saga elsewhere.

Now, just like the line from The Shining, and using the same scare tactics, “He’s back!”

Today in Paris, Mr. Séralini is telling people that all tests done on lab rats for the past decade or more–including his own–were invalid because of alleged “contamination” by GM ingredients and pesticides. He bases this conclusion on the fact that he was able to detect traces of GM proteins and glyphosate in the rat feed given to the lab rats.

Here’s our response:

Trace levels of various compounds in laboratory feed are not uncommon or surprising, and it certainly does not imply a feed safety risk.  Researchers already use diets that are certified to limit the maximum concentrations of many of these substances in order to be certain no health effects are triggered and that the results of their studies are valid. This paper irresponsibly misleads readers by insinuating conclusions that the authors did not even study and by calling into question every rodent toxicological study ever conducted – including their own.

BACKGROUND

The presence of trace levels of various compounds is not surprising and does not imply a feed safety risk.

Researchers specifically use diets that are certified to limit the maximum concentration of many of these substances.

Overall, as written, this paper is misleading and insinuates conclusions that were not even studied.  The authors are not calling into question our research – but every rodent toxicological study ever conducted, including their own.

DECLARAȚIE MEDIA:

Nivelurile de urme de diferiți compuși în hrana de laborator nu sunt neobișnuite sau surprinzătoare, și cu siguranță nu implică un risc de siguranță alimentară. Cercetătorii folosesc deja diete care sunt certificate pentru a limita concentrațiile maxime ale multora dintre aceste substanțe, în scopul de a fi siguri că nu sunt declanșate efecte asupra sănătății și că rezultatele studiilor lor sunt valabile. Această lucrare induce în eroare cititorii în mod iresponsabil insinuând concluzii pe care autorii nu le-au studiat și punând în discuție fiecare studiu toxicologic la rozătoare realizat vreodată – inclusiv al lor.
