A cross-sectional study on biosecurity practices and communication networks of poultry exhibition in Australia.

Poultry exhibitors are perceived to pose a biosecurity risk due to the high frequency of movements of birds and the close contact between birds at poultry shows. This cross-sectional study assessed the risks posed by poultry exhibitors in Australia using face-to-face interviews (n=46) at eight poultry shows and a postal survey. Univariable and multivariable logistic regression analyses were used to investigate associations between age, sex, location, number of birds, number of shows attended per year and distance travelled to a show, with biosecurity and communication practices. A total of 357 (29.1%) exhibitors responded to the postal survey. Among all participants (n=403), most had owned poultry for more than 15 years (71.9%), kept less than 200 birds (83.4%), mainly chicken (96.7%) and waterfowl (17.8%), and reported not having any commercial poultry operation within 5 km of their property (85.4%). Despite most exhibitors (90.8%) having at least some knowledge of biosecurity principles; some of their practices could pose a risk for disease introduction and spread. Most exhibitors kept their birds with outdoor access (87.0%) and 67.0% of exhibitors reported contact of wild birds with domestic birds being possible. Only 60% and 40.6% of exhibitors cleaned transport cages after each use and isolated birds for over two weeks, respectively, with men and exhibitors keeping more birds less likely (P=0.003) to conduct this practice. Most exhibitors (75.0%) attended more than 5 shows per year, travelling long distances (up to 1000 km) to attend a show. Although most exhibitors would source and sell their birds from and to other exhibitors and at poultry shows, some reported sourcing (15.2%) and selling (25.3%) their birds at live bird markets. In addition, contact with veterinarians was low (23.1%), with younger exhibitors and women more likely to contact a veterinarian than older exhibitors (P=0.006) and men (P=0.017). Other poultry exhibitors were reported as the most useful source of information, followed by the poultry club, the veterinarian and Internet. Less than a quarter of exhibitors perceived the government agencies as a useful source of information. Newspapers, newsletters, emails and websites were the preferred methods of information delivery. However, information seeking behaviour was found to differ significantly (P<0.05) among gender and different age groups. Differing biosecurity, health and communication practices among poultry exhibitors found in this study need to be considered for the development of successful biosecurity extension and communication programmes.
