backBrazil’s health regulator Anvisa has issued RDC 998/2025, a landmark rule that creates clear and standardized procedures for evaluating pesticide exposure risks among workers, applicators, nearby residents and people who circulate through treated areas. The measure fulfills requirements of the country’s new Pesticide Law and addresses a long-standing regulatory gap, since previous rules focused primarily on dietary risk to consumers.
The new regulation sets unified technical parameters, makes non-dietary risk assessment mandatory and requires companies to submit the Daroc dossier to demonstrate that proposed uses are safe. It also mandates the use of the national “avaliAR” calculator, which standardizes exposure estimates using Brazilian and international data, and introduces more realistic risk-reduction measures, including protective equipment tailored to actual field conditions.
Implementation will be phased in, applying both to new registrations and to updates of existing products. Anvisa will also publish a detailed technical guide and launch an online hub with manuals, formulas, tutorials and explanatory materials.
The agency expects the rule to significantly strengthen protections for rural workers and surrounding communities, raise the technical rigor of risk assessments and bring Brazil closer to leading international safety standards. The regulation enters into force 180 days after publication.
