This aim of this study was to assess the microbiological and anthelmintic drug residue risks associated with raw milk used for cheesemaking and raw milk cheese, over an 18-month period. Samples of raw milk, milk filters, curd and cheese from nine raw milk artisan cheese producers in the south of Ireland were tested. Numbers of presumptive Bacillus cereus group, Escherichia coli, Salmonella spp., Staphylococcus aureus and Listeria monocytogenes were determined. The determination of anthelmintic drug residues, including benzimidazoles, flukicides, macrocyclic lactone (avermectin and milbemycins), levamisole and morantel was also performed. Neither L. monocytogenes, nor Salmonella spp. were detected in any of the samples tested and no anthelmintic drug residues were detected. Only one of the samples did not conform with regulatory numbers for other bacteria. This survey has shown a good microbiological and residue quality (and low risk) of the raw milk cheese and raw milk used for raw milk cheese produced in Ireland. Moreover, it has shown the importance of frequent assessment of raw milk used for cheesemaking and for raw milk cheese, as it allows the identification of potential problems facilitating resolution of these issues before they cause any public health threat.

这项研究的目的是评估在18个月内与用于制奶酪和原料奶干酪的原料奶相关的微生物和驱虫药残留风险。测试了爱尔兰南部9家原奶工匠奶酪生产商的原奶，滤奶器，凝乳和奶酪的样品。确定了推测的蜡状芽孢杆菌组，大肠杆菌，沙门氏菌，金黄色葡萄球菌和单核细胞增生李斯特菌的数量。还进行了驱虫药残留物的测定，包括苯并咪唑，杀螨剂，大环内酯（阿维菌素和米尔倍霉素），左旋咪唑和莫兰特。无论是单增李斯特菌，也没有沙门氏菌属。在所测试的任何样品中均检测到了虫病，并且未检测到驱虫药残留。只有一个样品不符合其他细菌的法规编号。这项调查表明，在爱尔兰生产的生乳奶酪和用于生乳奶酪的生乳具有良好的微生物和残留质量（风险低）。此外，它表明了经常评估用于制干酪和用于原料乳干酪的原奶的重要性，因为它可以识别潜在问题，从而在这些问题引起任何公共卫生威胁之前促进解决这些问题。
