Some of us have suspected all along…pesticide is not good for you. When dealing with pests in our homes, some people prefer to “squish” rather than “spray”. Some prefer to escort the creature away politely, while many others practice prevention.
For the Agricultural industry, using chemicals is standard accepted proceedure, and has been the subject of an ongoing NIH study on the link between Parkinson’s Disease and pesticide.
New research shows a link between use of two pesticides, rotenone and paraquat, and Parkinson’s disease. People who used either pesticide developed Parkinson’s disease approximately 2.5 times more often than non-users.
The study was a collaborative effort conducted by researchers at the National Institute of Environmental Health Sciences (NIEHS), which is part of the National Institutes of Health, and the Parkinson’s Institute and Clinical Center in Sunnyvale, Calif.
“Rotenone directly inhibits the function of the mitochondria, the structure responsible for making energy in the cell,” said Freya Kamel, Ph.D., a researcher in the intramural program at NIEHS and co-author of the paper appearing online in the journal Environmental Health Perspectives. “Paraquat increases production of certain oxygen derivatives that may harm cellular structures. People who used these pesticides or others with a similar mechanism of action were more likely to develop Parkinson’s disease.
The authors studied 110 people with Parkinson’s disease and 358 matched controls from the Farming and Movement Evaluation (FAME) Study to investigate the relationship between Parkinson’s disease and exposure to pesticides or other agents that are toxic to nervous tissue. FAME is a case-control study that is part of the larger Agricultural Health Study, a study of farming and health in approximately 90,000 licensed pesticide applicators and their spouses.
There are no home garden or residential uses for either paraquat or rotenone currently registered. Paraquat use has long been restricted to certified applicators, largely due to concerns based on studies of animal models of Parkinson’s disease. Use of rotenone as a pesticide to kill invasive fish species is currently the only allowable use of this pesticide.
“These findings help us to understand the biologic changes underlying Parkinson’s disease. This may have important implications for the treatment and ultimately the prevention of Parkinson’s disease,” said Caroline Tanner, M.D., Ph.D., clinical research director of the Parkinson’s Institute and Clinical Center, and lead author of the article.
The NIEHS supports research to understand the effects of the environment on human health and is part of NIH.
The National Institutes of Health (NIH) is the Nation’s Medical Research Agency and includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. It is the primary federal agency for conducting and supporting basic, clinical and translational medical research, and it investigates the causes, treatments, and cures for both common and rare diseases.

On the subject of chemicals and pest control – in at least one Gilbert, Arizona home, the capture/release method is preferred over pesticide use, and is utilized 95% of the time. All bets are off, however, when it comes to large spiders. The exception to the large spider squishing policy would be “Granddaddy Long Legs”. How one could contemplate squishing something with the word “Granddaddy” in it is beyond me.
