Abstract

AbstractHuman consumption of sea turtles remains prevalent throughout Mexico even though laws restricting trade and take of threatened and endangered species have been in place for several decades. The illegal consumption of sea turtles represents a risk to animal conservation, and the pathogens in the meat can adversely affect human health. In 2017, we surveyed 201 adult residents of 22 coastal communities about their diets, health, and attitudes about the environment, and we collected hair samples that were tested for heavy metals. A large percentage of the samples had high levels of mercury (87%), arsenic (81%), lead (65%), aluminum (57%), and cadmium (31%). Odds ratios suggested that the 28% of participants who reported recent sea turtle consumption had an increased likelihood of high metal levels even after adjusting for sex, age, and consumption of fish that bioaccumulate heavy metals. Conservation efforts may be more successful when they appeal to people's self‐interest rather than merely focusing on ecological benefits. Concerns about toxins in sharks, tuna, and other types of deep‐sea fish have reduced human consumption of some species. Both sea turtle conservation and human health may benefit from awareness campaigns that emphasize the adverse outcomes associated with eating sea turtles while continuing to affirm the economic benefits of healthy ecosystems. Transdisciplinary research that draws on ecology, epidemiology, toxicology, law, and public policy provides a valuable foundation for solving complex health issues. Creative reframing of biodiversity concerns will be necessary for promoting planetary health in a time of accelerating environmental change.
