Public Perception of Pesticide Exposure in Vermont

Introduction. Pesticides include chemicals and biological agents used to prevent, destroy, or mitigate pests.  Overexposure may cause acute and chronic health effects.  Studies indicate varying levels of public awareness and knowledge of exposure sources and health risks. It is vital to gauge knowledge and perceptions to identify areas for improved communication and outreach.

Methods. A 22-question survey was developed to assess Vermonters’ perception, exposure, and demographics, and was distributed at 6 locations in Vermont (n=240).  10% of surveys were randomly selected for quality control.  Data were analyzed using Excel, GraphPad, and Fisher’s exact test. 

Results. Of the 240 respondents, 48% were male and 52% were female. 81% had an undergraduate degree or higher. 37% were 18-44yr and 64% were 45yr or older. 93% reported using pesticide-containing products, although only 29% of respondents indicated self-reported pesticide exposure in the last year. Food ranked first for greatest personal source (33%) and perceived risk (31%) of pesticide exposure.  More women than men were concerned/very concerned about the health effects from exposure (p=0.0031). Of respondents, 31% were confident in their healthcare professional’s knowledge about pesticide exposure; only 10% were confident in their personal knowledge.

Conclusions. The vast majority of Vermonters (93%) reported using pesticides while only 29% reported pesticide exposure. Given disparity between public use and perception, further education of the public about sources of pesticides, health risks, and precautions is essential.  Increasing healthcare professionals’ knowledge and discussions with patients about pesticide use could complement public education strategies, and be used in other locations.
