Barbara Allegrezza, et al. v. Monsanto Co.

Summary

In this trial, Mark McCostlin developed non-Hodgkin lymphoma, which his representatives claim was due to his use of Monsanto's Roundup herbicide. Plaintiffs allege that Monsanto was aware of Roundup's carcinogenic risks yet hid them for financial gain.

Defendant Monsanto claims that Roundup is safe and that studies showing an increase in cancer from glyphosate, an active ingredient in the herbicide, rely upon flawed science.
