Pesticide exposure among farmers linked to poor sense of smell later
A Michigan State University study is the first to show an association between unusually high pesticideexposure and poor sense of smell among aging farmers.
The research examined more than 11,200 farmers over a 20-year period. At the start of the study, about 16 percent of participants reported having experienced a high pesticide exposure event, or HPEE, such as a large amount of pesticide spilling on their body. Two decades later, they were asked if they suffered olfactory impairment, a partial to complete loss of sense of smell.
