Abstract/OtherAbstract:
Food safety is a critical factor in the production of farmhouse cheese. In Ireland the varieties of farmhouse cheese produced reflect a much broader range than those produced commercially and some of these cheese varieties are associated with greater microbiological risk. These include cheese produced from unpasteurised milk and soft ripened cheese such as mould or smear-ripened cheeses which have high pH and relatively short ripening times. The aim of this study was to determine the microbiological quality of farmhouse cheeses in Ireland. Three hundred and fifty one cheese samples, from 15 cheese producers, were analysed for microbiological quality on a monthly basis throughout the year. The analyses included enumeration of Escherichia coli, Staphylococcus aureus and Listeria monocytogenes (using the relevant agars) and enrichment for L. monocytogenes. The cheeses selected were produced from ovine, caprine and bovine milk. Both unpasteurised and pasteurised milk cheeses were sampled and these included hard, semi-hard and soft cheeses, internal/external mould-ripened and smear-ripened cheeses and the cheeses represented different geographic regions. Of the cheeses tested, 94% were free of L. monocytogenes, all were within the EU limits for E. coli and only one cheese variety had S. aureus levels above the recommended numbers for the first 6 months of the year. Due to a modified production process the numbers were within the guidelines for the second six months. The results indicate that Irish farmhouse cheeses are of a high microbiological quality.
