The Government’s first priority with regard to pesticides is to ensure that they will not harm people or pose unacceptable risks to the environment. A pesticide may only be placed on the market in Great Britain if the product has been authorised by our expert regulator, the Health and Safety Executive (HSE), following a thorough risk assessment
It has been illegal to sell or use paraquat in the UK since 2007. HSE has therefore not carried out a recent risk assessment.
HSE is aware that several studies have been undertaken investigating associations between exposure to paraquat and Parkinson’s disease. HSE is not aware that a causal link has been demonstrated.
