About this episode

Lianne Sheppard discusses the implications of glyphosate use and findings from the Seattle Glyphosate Symposium.

Did you know that glyphosate is the most commonly used herbicide in the world, and because of its ubiquitous use, glyphosate can be found in most of our bodies? Join Food Sleuth Radio host and Registered Dietitian, Melinda Hemmelgarn for her conversation with Lianne Sheppard, PhD, Professor in the Departments of Environmental and Occupational Health Sciences, and Biostatistics at the University of WA-Seattle. Sheppard discusses highlights and conclusions from the Seattle Glyphosate Symposium, and the risks from long term, low-level exposure. She also discusses why EPA registration of a pesticide does not mean that the pesticide is safe. To see the pesticides (insecticides, herbicides, fungicides and rodenticides) used in your part of the country, see the USGS maps of pesticide use: https://water.usgs.gov/nawqa/pnsp/usage/maps/compound_listing.php Related Websites: Glyphosate symposium : https://deohs.washington.edu/sgs/statement
