My wife used to administer Medical services in Santa Barbara country: coordinating translators and a program providing insurance to undocumented children. Many of the recipients worked the fields and I was always astonished to hear the frequency of occurrence of certain birth defects in these populations.

It's entirely possible the occurrence wasn't elevated relative to populations she didn't work with or I didn't hear about... but I've long suspected that there's a story hiding in plain sight that's bigger than even the recent cancer-related damages. Especially given that many of the workers are Mixtec and so are incredibly isolated from society-at-large (many would pretend to understand Spanish and didn't realize they could request Mixtec-speaking translators).
