“…Warmer seas may contribute to increased cases of human shellfish and reef-fish poisoning (ciguatera) in tropical regions and a poleward expansion of the disease (14)(15)(16)(17). However, there is little new evidence that climate change significantly alters the prevalence of these diseases.…”

This article reviews the potential impacts of climate change on food security. It is found that of the four main elements of food security, i.e., availability, stability, utilization, and access, only the first is routinely addressed in simulation studies. To this end, published results indicate that the impacts of climate change are significant, however, with a wide projected range (between 5 million and 170 million additional people at risk of hunger by 2080) strongly depending on assumed socio-economic development. The likely impacts of climate change on the other important dimensions of food security are discussed qualitatively, indicating the potential for further negative impacts beyond those currently assessed with models. Finally, strengths and weaknesses of current assessment studies are discussed, suggesting improvements and proposing avenues for new analyses.hunger ͉ vulnerability ͉ food supply ͉ agriculture

“…Given this population's substantial reliance on marine resources, we suspected that ciguatera fish poisoning might be a significant health threat. Ciguatera poisoning is the most common form of fish poisoning and afflicts populations dependent on marine resources throughout the tropics Lehane & Lewis (2000). Ciguatera toxins are produced by a marine dinoflagellate associated with macroalgae and accumulate up the food chain, most commonly achieving dangerous levels in large, often predatory, fishes Hokama & Yoshikawa-Ebesu (2001).…”

The evolution of cultural adaptations: Fijian food taboos protect against dangerous marine toxins

The application of evolutionary theory to understanding the origins of our species' capacities for social learning has generated key insights into cultural evolution. By focusing on how our psychology has evolved to adaptively extract beliefs and practices by observing others, theorists have hypothesized how social learning can, over generations, give rise to culturally evolved adaptations. While much field research documents the subtle ways in which culturally transmitted beliefs and practices adapt people to their local environments, and much experimental work reveals the predicted patterns of social learning, little research connects real-world adaptive cultural traits to the patterns of transmission predicted by these theories. Addressing this gap, we show how food taboos for pregnant and lactating women in Fiji selectively target the most toxic marine species, effectively reducing a woman's chances of fish poisoning by 30 per cent during pregnancy and 60 per cent during breastfeeding. We further analyse how these taboos are transmitted, showing support for cultural evolutionary models that combine familial transmission with selective learning from locally prestigious individuals. In addition, we explore how particular aspects of human cognitive processes increase the frequency of some non-adaptive taboos. This case demonstrates how evolutionary theory can be deployed to explain both adaptive and non-adaptive behavioural patterns.

“…In some cases, the disease progresses with prolonged neurological symptoms including chronic fatigue, weakness and depression. A chronic phase of CFP lasting many years has also been reported in up to 20% of those acutely exposed [1,6,12,13] but CFP sometimes causes death (case fatality rate, 0.1-20%, depending on the area of impact). Sometimes, cardiovascular symptoms appear such as palpitations.…”

“…Sometimes, cardiovascular symptoms appear such as palpitations. Stress, excessive alcohol consumption, and ingestion of non-toxic fish may induce a recurrence of symptoms [13]. Treatment of ciguatera is only symptomatic by the use of antiemetic, antidiarrheic, antihistaminic, analgesic and vitaminotherapy.…”
