Low-Level Pesticide Exposure Linked to Parkinson's Disease
 

Apparently it doesn't take much to do the job.

I can certainly attest to pesticide exposure! My husband's summer jobs during college included some limited extermination work but also he dusted crops in west Texas with his small plane using an agent that was later identified as being Agent Orange! It is theorized that this may have also contributed to the severe case of colon cancer he had 20 years ago without having it in his family.
