Biosecurity Questionnaire

Protecting Your Pig at the Show

Biosecurity Poster

A very special thanks to Dr. John Carr for making this very important document possible. Dr. Carr has proven himself a steadfast friend to the potbelly pig and those who share their lives with these fascinating but complex little creatures. In addition to all of his help in treat sick pigs, Dr. Carr has helped helped to keep countless pigs alive and healthy through his education in proper biosecurity techniques.

The rough draft of this document was presented to the North American Potbellied Pig Association Biosecurity Committee by the Chairman of that committee, Lorelei Pulliam, on December 7, 2005 for review and final revision. The idea and format of the checklist was originally created by Dr. Morgan Morrow of North Carolina State University. That checklist was reviewed, revised by the National Pork Board/American Association of Swine Veterinarians (AASV)Biosecurity Working Group and the National Pork Swine Health Committee, and the AASV Swine Health Committe, and Dr Sandy Amass, Director of the National Biosecurity Resource Center at Purdue University. Thanks to all of them, too!

This is an evolving and critical issue for all pig owners. Stay tuned as more information becomes available.

Bedding is stored with good rodent control measures	Excellent
Manure disposal:
Manure is piled close to the pig’s housing	Questionable

Rodents, feral animals and birds can be sources of pathogens for pigs. Rodents can carry the agents that cause Progressive Atrophic Rhinitis (Pasteurella), Escherichia coli scours, Leptospirosis, rotaviral diarrhea, Salmonellosis, and Swine Dysentery. Dogs can spread Swine Dysentery and Brucellosis pathogens. Wild animals can harbor Brucellosis, Leptospirosis, and Pseudorabies. Birds can carry bordetellosis and tuberculosis. There is also evidence that birds can transmit the viruses that cause Classic Swine Fever, PRRS, Influenza and TGE. Cats are a potential source of toxoplasmosis. Flies and mosquitoes can transmit PRRSv. It is difficult to control bird and other animals in outdoor facilities. This makes it paramount that managers be more cautious and observant. It must be remembered that the best biosecurity measures in the isolation facility will be thwarted if small animals are tracking their unwashed feet between groups of pigs or carrying pathogens from sick to well pigs.
