This purpose of this poster is to provide an approach to biosecurity in a zoo for preventing and managing infectious diseases that could threaten the health of the animal collections, employees, guests, and others on or using the zoo facilities. According to the U.S. Department of Agriculture, the word “biosecurity” is defined as those precautions taken to minimize the risk of introducing an infectious disease into an animal population.8 We use the term to refer to all programs of infection control within a zoo facility. Several publications are available to help in formulating general biosecurity measures in zoos.1-7
These general guidelines can be used by veterinarians in zoos to set up procedures for staff, volunteers, and contractors that work with and around animals in zoo facilities. Biosecurity procedures for specific diseases or circumstances can be addressed separately (e.g., primate safety guidelines, bat handling guidelines, reptile handling guidelines, highly pathogenic avian influenza, and exotic Newcastle disease,6 etc.).
Categories of biosecurity measures can include those for facilities, animal care staff, collection animals, animal feed, wild and feral animals, routine disease surveillance, biosecurity communications and education, employee preventive and occupational health care, and enhanced biosecurity and control measures in the event of a foreign animal disease in the region.
A group of senior zoo staff can be assigned to address infectious disease and zoonosis threats. The group can draft, approve, and periodically review biosecurity guidelines and convene as needed to address specific infectious disease situations.
The authors acknowledge the collaborative contributions that were provided by the Collection Health and Curatorial Staff of the Zoological Society of San Diego in the creation of these guidelines.
