Research Project: Environmental Management Strategies for Improving Health and Well-being in Poultry Production

Location: Poultry Research

Project Number: 6064-13000-014-005-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 31, 2019
End Date: Jul 30, 2024

1. Analyze data from bio-aerosol samplers (3.a.1). 2. Determine concentration and size distribution of airborne E. coli particles in poultry houses (3.a.2). 3. Develop Ultraviolet (UV) radiation and Electrostatic Particle Ionization (EPI) systems applicable to airborne APEC mitigation (3.a.3). 4. Application of techniques to promote bird health and productivity.

To evaluate and compare sampling performances, the 3 bio-aerosol samplers will be used to collect E. coli-laden dust particles generated by an automated system. The bio-aerosol samplers will be aligned and will perform air sampling simultaneously for 30 mins. The test will be repeated 21 times. Captured particles (CFU m-3) will be assessed and results will be analyzed. Results will be applied to the assessment of airborne E. coli concentration and size distribution in broiler and egg layer facilities over a course of 2 years. Both temporal/seasonal and spatial impacts will be considered, and APEC strains will be differentiated via molecular-based means. Utilizing previously identified bio-aerosol samplers and test chambers, Ultraviolet (UV) radiation and Electrostatic Particle Ionization (EPI) systems will be evaluated to mitigate airborne E. coli.
