  • Project start date: 1 January 2005
  • Project status: Completed
  • Project type: Food safety
  • Discipline: Microbiology and food hygiene
  • Author/s: Mr Jim Buckley, Cork County Council
  • Collaborator/s: Single supplier

Research objective

The objective of this project was to conduct a comprehensive surveillance and monitoring programme of milk production holdings—specifically bovine, ovine, and caprine farms—that supply milk for farmhouse cheese production. The aim was to establish baseline data on the prevalence and characteristics of key pathogens that pose food safety risks in unpasteurised dairy products.

The pathogens of interest included Salmonella, Campylobacter, Listeria, Enterobacteriaceae, Staphylococcus aureus, and Mycobacterium avium paratuberculosis. By monitoring these pathogens across various seasonal cycles, the project sought to generate crucial information for risk assessment and epidemiological investigations. This data is intended to enhance understanding of the potential food safety risks associated with unpasteurised dairy products, thereby informing and improving risk management strategies and safety protocols in the production of farmhouse cheese. The project was funded collaboratively by safefood and the Food Safety Authority of Ireland.
