Dear Commissioner,
A recent publication1 highlights the fact that the authors of two neurodevelopmental toxicity studies on chlorpyrifos and one on chlorpyrifos-methyl, commissioned by for regulatory purposes to evaluate the safety of these substances, have failed to correctly report all the adverse effects observed in pre- and post-natally exposed rat pups. The industry-sponsored studies2 in question are in line with the international OECD test guideline protocol and they were funded by (at the time) Dow Chemicals in the frame of the registration process for these 2 substances for approval. Today, Dow Chemicals has been rebranded “Corteva”3, the agricultural division of DowDupont.
