Infections Associated with Exotic Cuisine: The Dangers of Delicacies

"Exotic" food dishes are an expression of regional culture, religion, and ethnicity worldwide. With the increase in international travel to remote areas of the world, globalization of the food supply, and changes in food habits, more people are consuming dishes once considered exotic. Such behavioral changes require awareness by consumers and clinicians about the risks of food-borne infections. This chapter addresses pathogens associated with consumption of raw or undercooked seafood including anisakidosis, Diphyllobothrium latum infection, flukes, and other infectious and toxin-mediated diseases. We discuss the geographic distribution of the pathogens, symptomatology, and basic principles of treatment. Food products derived from turtles, snakes, and other reptiles are reviewed, and we address the risk of gnathostomiasis, sparganosis, trichinellosis, and other pathogens. In discussing infections associated with undercooked beef, pork, and bush meat, we address dysentery, amebiasis, toxoplasmosis, Taenia infections, and risks of novel viral infections, among others. We also review infectious risks from poultry, dairy, and other food items, focusing on those organisms encountered less frequently by clinicians in developed countries. The wide range of infectious organisms related to exotic cuisine underscores the importance of educating the adventurous traveler and warrants continued vigilance on the part of the clinician.
