Toxic chemicals in pet flea treatments harming wildlife, UK study warns
A UK study warns that toxic chemicals in pet flea treatments are harming wildlife and potentially affecting human health. The chemicals fipronil and imidacloprid, banned for use as pesticides, are causing irreversible damage to aquatic life and bird populations. Urgent government action is needed to limit these harmful substances, as their presence in the environment is linked to declining wildlife and cognitive issues in children with autism.
- ▪Chemicals banned as pesticides are still used in flea treatments, harming wildlife.
- ▪Fipronil and imidacloprid are linked to lower cognitive scores in children with autism.
- ▪The government is urged to conduct an environmental risk assessment and consider banning these flea treatments.
