GM microorganisms pose huge challenges for risk assessment and governance

A recent review by researchers from Environment Agency-Austria, Austrian Academy of Sciences and the German Federal Agency for Nature Conservation identifies critical biosafety and wider governance risks of environmental applications of genetically modified microorganisms (GMMs), including those developed by genome editing. It focuses on two case studies of commercialised applications: 1) GM microalgae for biofuel production and 2) GM soil bacteria for increased nitrogen fixation. GMMs are “fundamentally different to GM higher organisms”, raising specific challenges. Their microscopic size complicates detection of their environmental presence, hindering assessment and monitoring of their survival following intended or accidental release. Bacteria and microalgae also readily exchange DNA via horizontal gene transfer, raising the risk of spread of both intended and unintended engineered sequences and traits. Moreover, bacteria are capable of rapid genetic change, with the potential for evolutionary adaptation, providing “new opportunities to evolve, adapt, and spread”. Third World Network via GMWatch

Bayer increases its spending on lobbying in Iowa since introduction of pesticide labelling bill

Bayer, the biotech company and manufacturer of Roundup, has substantially increased its spending on lobbying in Iowa since the introduction of a pesticide labelling bill (the “cancer gag act”) in 2024. In 2025, according to client reports published by the state, Bayer paid lobbyists $123,250. Reports for 2024 show $86,099 spent. Between 2021 and 2023, years before the pesticide labelling bill was introduced, Bayer spent annually between $20,000 and $30,000 on its lobbying efforts. Iowa Capital Dispatch

India should learn from Bt cotton fiasco

After the GM Bt cotton fiasco, pushing GM maize with glyphosate tolerance is repeating a dangerous mistake, writes policy analyst Devinder Sharma. Punjab Agricultural University has been given the go-ahead to conduct field trials of Bayer’s GM herbicide-tolerant and insecticidal maize. @Agri4Food on X
