EU pesticide reforms spark backlash from scientists over weakened safeguards

Researchers from 27 European institutions have raised concerns over proposed changes to the EU’s pesticide approval process. They warn that the Omnibus Package could weaken key safeguards designed to protect health and the environment. The group has put forward alternative measures to improve transparency and efficiency in evaluations. Under current rules, active substances in pesticides must undergo regular re-evaluations. Since 2011, 59 substances have failed reapproval due to health or environmental risks. The Omnibus Package, however, would grant most substances indefinite approval, ending these periodic reviews.

The proposed changes would also shift the burden of proof from manufacturers to authorities. At the same time, the role of scientific evidence in national product authorisations would be reduced. Additionally, banned substances could remain in use for up to three years after their phase-out date.

In response, the researchers propose several improvements. They recommend standardised assessment criteria and clearer responsibilities for manufacturers to provide proof of safety. Public access to approval studies should also be guaranteed. To catch risks after authorisation, they suggest linking pesticide usage data to monitoring systems and expanding residue measurements. The researchers argue that their proposals would strengthen the approval process. Faster evaluations could be achieved by assigning tasks based on expertise. Their measures aim to ensure the system remains scientifically robust, transparent, and efficient without compromising safety standards.
