Summary
WHO human and non-target safety review of Bti, including use in drinking-water containers.
Key findings
Bti is not considered to pose a hazard to humans through drinking-water and is recommended under WHOPES for control of container-breeding Aedes aegypti even in water receiving little or no further treatment.
Limitations
Safety conclusion is qualitative and emphasizes the need for a properly assayed, quality-controlled product.
