Why is this research important for Alberta ag?
The current highly pathogenic avian influenza (HPAI) outbreak in Alberta has impacted 32 poultry flocks including 20 commercial poultry operations leading to depopulation of close to one million birds. The HPAI outbreak is linked to H5N1 sub type, and it has been attributed to death of migratory and non-migratory wild birds as well as some mammals.
Although the outbreak impacted poultry operations severely during the winter and spring, the number of cases has declined during the summer with only one case recorded during July. It is expected that cases will increase with the cooler temperatures during the fall and winter. However, it is not clear that original mode of transmission of HPAIC to the impacted poultry operations as to contamination of water and air by migratory wild birds or farm to farm spread. It is also not clear if non-migratory birds living at the vicinity of poultry operations are also playing a role in viral transmission.
This research aims to understand if the original mode of introduction of HPAICV to the layer flocks is contaminated water or air by migratory wild birds, determine the airborne HPAIV in primary control zone of HPAIV infected premises in order to understand the risk of airborne spread, and determine if non-migratory birds are playing a role in the contamination of layer premises.
What benefits can producers expect from this research?
Outcomes from this project will help define effective, science-driven biosecurity procedures, and outbreak control measures. Given the economic importance and also the public health importance of HPAI, this research project has the potential to provide a major contribution to the Alberta’s poultry industry in addition to indirectly addressing some public health issues relevant to personnel in contact with poultry. This research project will have a strong impact on fundamental understanding of the transmission of HPAIV among poultry flocks, and as such, the advancement of science.
