Australia paused the use of a common berry pesticide after rising consumption increased potential exposure, especially for young children. Australia’s agricultural regulator has temporarily halted the use of a widely used pesticide called dimethoate on blueberries, raspberries, and blackberries. The one-year suspension is not based on new evidence about the chemical itself. Instead, the Australian [...]

Products have been confirmed to contain chemicals such as paraquat, paraquat dichloride, dimethoate and acephate, which pose serious risks to human health, plant health and the environment

The federal pesticide authority has updated how the chemical dimethoate can be used on berries after new data confirmed skyrocketing consumption has been putting young children over the safety limit.

...Seventeen highly dangerous pesticides are still traded Experts say the use of dangerous pesticides and agrochemicals by farmers and traders to protect crops, control weeds and store food products is quietly poisoning Nigerians and damaging their health and the environment. Some of the most hazardous pesticides include: atrazine, butachlor, dichlorvos, carbendazim, cypermethrin, dimethoate, duron, endosulfan, glyphosate, and imidacloprid. Others include carbofuran, chlorpyrifos, paraquat, mancozeb and permethrin.

Australia’s regulator has suspended use of a common pesticide used on blueberries, raspberries and blackberries known as dimethoate.

Comprehensive profiling of impurities in organophosphorus pesticides, such as dimethoate, remains challenging due to their structural diversity, trace abundance, and analytical constraints. This can be overcome by integrating multiple analytical techniques to enhance impurity profiling of pesticides, particularly dimethoate, but little has so far been carried out in this field. Herein, a novel integrated analytical platform, synergizing high-performance liquid chromatography-diode array/charged aerosol detection (HPLC-DAD-CAD) with Orbitrap high-resolution mass spectrometry, empowered by MS-DIAL/SIRIUS artificial intelligence-driven annotation, was developed. The chromatographic conditions (column, mobile phase additive, organic phase, sample solvent, and gradient program) were optimized. The dual-detector synergy strategy simultaneously captured chromophoric and attenuated chromophoric species. Innovatively coupling MS-DIAL and SIRIUS identified three known impurities and 15 novel structures by a workflow leveraging spectral deconvolution, sub-ppm molecular formula prediction, and fragmentation modeling. Under the optimized setting, the method achieved a detection limit of 0.03 µg g⁻1 and trace level sensitivity ≥0.01%. The fragmentation pathways were also demonstrated for a total of three key impurity classes (phosphorothioate esters, disulfide-linked compounds, and alkyl-modified derivatives), linking their formation with synthetic routes and storage degradation. Overall, the proposed extensible analytical framework establishes the foundation for pesticide impurity surveillance, strengthening reference material certification, production optimization, and agrochemical safety governance.

Australia suspended dimethoate on berries as rising consumption may raise exposure risks for young children; washing berries reduces residues to keep them safe.
