Fipronil is a broad-spectrum phenylpyrazole insecticide. It is authorised in the EU for use in veterinary medicine to combat insects control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects. It is not permitted for use on food-producing animals. Fipronil-sulfone is the primary biological metabolite of fipronil and Fipronil-desulfinyl is the primary environmental metabolite. The Maximum Residue Limit (MRL) for fipronil is expressed as the sum of fipronil and fipronil sulfone and has been set at 0.005mg/kg (5ppb) in the European Union. Fipronil is not carcinogenic. Animal studies carried out by the European Food Safety Authority (EFSA) and the World Health Organisation (WHO) reported adverse effects on the nervous system were observed after short-term exposure.
