title: Diseases Transmitted by Domestic Livestock: Perils of the Petting Zoo.
abstract: Petting zoo venues encourage or permit public contact with animals which provide opportunities for education and entertainment. These venues vary but are common at county or state fairs, zoos, and aquariums. In addition to these common petting zoo settings, animals are present in many other venues where the public is permitted to contact them and their environment. Thus, humans may have contact with animals in a wide range of settings, and transmission of infectious diseases from animals to humans may occur at any of these venues, creating perils associated with petting zoos.There are many considerations when evaluating perils associated with the wide range of venues where animal contact can occur. First, many venues or events draw large numbers of people; some operate during a short time frame, while others, such as zoos and aquariums, operate year round. Second, petting zoos and other animal contact venues are particularly popular with children, who compared with adults, commonly have less stringent hygienic practices and are more susceptible to severe disease outcomes. Finally, there is remarkable variability in the physical layout of venues that permit animal contact and in the types of animals that may be contacted. Animal contact areas range from well-designed permanent exhibits targeting risk reduction to various temporary or seasonal exhibits established without detailed planning. Many petting zoos house only small ruminant species such as sheep and goats, but other venues house a wide variety of mammalian species, exotic animals, poultry and other avian species, reptiles and amphibians, and aquatic animals.
