Abstract

Glyphosate is currently the most widely used herbicide in the world. Initially thought to be non-carcinogenic in humans, in 2015 glyphosate was classified as a “probable carcinogen” by the International Agency for Research on Cancer due to several small epidemiological studies indicating a link between the pesticide and hematologic cancers, especially non-Hodgkin’s lymphoma (NHL). The current work is an ecological study using counties in Kentucky, Arkansas, and Iowa to compare glyphosate usage to NHL incidence using a multivariate Poisson regression. We found no significant correlation between glyphosate use and NHL incidence, though caution should be taken to draw significance from a population-level study. Future work should revisit large cohort studies to further investigate this potential link.
