Pesticide exposure linked to higher motor neurone disease riskPeople who are exposed to pesticides through their work may face a significantly higher risk of developing amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND), according to a new review of international research. Overall, occupational exposure to pesticides was associated with a 1.6-fold increase in ALS risk. Despite these limitations, the researchers say the review strengthens the evidence that occupational pesticide exposure could be an important risk factor for ALS. The findings also highlight the importance of measures to reduce pesticide exposure in workplaces, particularly in sectors such as agriculture, horticulture and grounds maintenance, where regular contact with these chemicals is common. The researchers say improving exposure monitoring and strengthening workplace protections could help reduce the risk while further research continues.
