The Devils' Fruit describes the features and facets of the strawberry industry as a harm industry, and explores author Dvera Saxton's activist ethnographic work with farmworkers in response to health and environmental injustices. She argues that dealing with devilish - as in deadly, depressing, disabling, and toxic - problems requires intersecting ecosocial, emotional, ethnographic, and activist labors. Through her work as an activist medical anthropologist, she found the caring labors of engaged ethnography take on many forms that go in many different directions. Through chapters that examine farmworkers' embodiment of toxic pesticides and social and workplace relationships, Saxton critically and reflexively describes and analyzes the ways that engaged and activist ethnographic methods, frameworks, and ethics aligned and conflicted, and in various ways helped support still ongoing struggles for farmworker health and environmental justice in California. These are problems shared by other agricultural communities in the U.S. and throughout the world.
