Committee Report Questions Parasite Drug Use and Environmental Impact

The Environment and Climate Change Committee's report says intensive use of parasite medications lacks robust scientific backing and that chemicals like fipronil and imidacloprid, banned as agricultural pesticides due to wildlife risks, are entering rivers and land. Peers recommend treatments be sold only through vets, pharmacists, or trained staff, with thorough animal assessments and clearer risk labeling. They also call for stronger evidence on environmental and human health impacts, a precautionary approach to reduce unnecessary use, and a review of industry ties to regulators. The report notes that very little is known about the long-term effects of these chemicals on ecosystems and human health.
