'A review of research from Belgium's Catholic University of Louvain has confirmed that Parkinson's disease is linked to occupational exposure to pesticides.
The researchers, working with the Louvain Center for Toxicology and Applied Pharmacology, analyzed studies between 1985 and 2011 that looked at pesticide exposure by workers who handled pesticides. These included farm workers who sprayed pesticides.
The overall conclusion of the research found that those who handled pesticides were significantly more likely to contract Parkinson's disease. In four studies, where the Parkinson's diagnoses were confirmed by neurologists, those handling pesticides had an average of over two-and-a-half times the risk of contracting Parkinson's disease. The increased risk ranged from 46% higher to almost four-and-a-half times higher among the workers.'
