Veterinary Public Health

Veterinary Public Health

Veterinary Public Health (VPH) is a broad and diverse subject area considering the numerous direct and/or indirect interactions we as humans share with animals. Research in this area within the School focuses primarily on the safety of foods of animal origin. Animals are universally recognised as a significant reservoir of zoonotic microbiological hazards and contaminated foods are frequently implicated as vehicles responsible for disseminating these infectious agents to humans.

Research efforts are directed at the pre-harvest, harvest and post-harvest phases of the food chain. On this basis, it is essential that prevalences of these microorganisms are established and effective control measures identified in the various food chains to reduce the risk of human exposure. Research projects can entail surveillance studies designed to establish the prevalence, levels and significance of microbial hazards in food animals and foods of animal origin.  

Furthermore, targeted studies are also used to try and identify significant risk factors responsible for colonisation in animals by human enteropathogens and the dissemination of these agents during transportation, slaughter and processing. These investigations frequently involve both phenotypic and genotypic characterisation of microbiological hazards. In addition, zoonotic agents are frequently characterised as part of our research based on their virulence/pathogenicity and antimicrobial resistance profiles in order to ascertain a more accurate assessment of the risks they may pose to human health.  

We have external research partnerships with colleagues in various institutions and agencies, including Teagasc, Dept. of Agriculture, Food & the Marine, Food Safety Authority of Ireland, Cork Institute of Technology, Trinity College Dublin and NUI Galway. There are also interesting collaborations with colleagues in the UCD School of Agriculture & Food Science which have led to a number of research projects assessing the ability of novel non-thermal food processing technologies such as High Intensity Light Pulses (HILP), Pulsed Electric Fields (PEF), Ultrasonication (US) and Ultraviolet light (UV) to inactivate foodborne pathogens, improve food quality attributes and enhance shelf-life.  

Outputs of research in this area within the School can be disseminated to regulatory agencies, public health professionals and the Irish Agri-food sector, with the ultimate aim of improving human health through enhanced food safety whilst also facilitating the development of a more competitive and sustainable Agri-food sector in Ireland. In addition, the training and development of graduate research students and post-doctoral researchers is another important output from our VPH research programmes as they are a valuable human resource for both public bodies as well as the Irish Agri-food sector.
