ResumenThis chapter addresses (1) the distribution and abundance trends of key wildlife hosts of food-borne zoonotic infections in Europe; (2) some representative case-studies regarding food-borne zoonoses shared with wildlife, with particular regard to the role of direct and indirect human-livestock-wildlife interactions; and (3) the efforts required to monitor and eventually control diseases shared with wildlife. Zoonotic agents may reach human beings both direct from wildlife, e.g. through game meat manipulation and raw consumption, or indirectly through contaminated vegetables or through the infection of livestock which might in turn transmit the agent to human beings. However, not all wildlife species have the same relevance, and not all taxa have been studied deeply enough to reveal their actual role as a source of human pathogens. Given the widespread distribution and the current trends of wildlife populations, and their close interaction with humans and domestic animals, prevention remains the best tool for limiting the occurrence of wildlife-related food-borne zoonotic disease events. However, it is advisable to monitor both disease prevalences and wildlife populations in order to record any significant changes and take action accordingly. Predicted future changes include growing abundances of certain relevant host species, notably synanthropic birds and rodents and opportunistic species such as the wild boar and the red fox. Along with this, increased farming, translocating and feeding of wildlife will also contribute to create appropriate environments for zoonotic pathogen emergence. Disease control efforts, even if restricted to a minority of pathogens, are therefore predicted to become more common.
