Abstract The microbiological status of raw milk sold from vending stations at farm level in northern Germany was determined in relation to hygiene quality parameters and the presence of foodborne pathogens. For this, one hundred and ten samples were examined. The total viable count (TVC) was higher than 5 log cfu mL−1 in 36.4% of the milk samples. Counts of Pseudomonas spp., Enterobacteriaceae, yeasts and moulds were detected at mean values of 3.9 ± 1.3 log cfu mL−1, 2.7 ± 1.2 log cfu mL−1, 3.1 ± 0.9 log cfu mL−1 and 1.5 ± 0.8 log cfu mL−1, respectively. Overall, only 43% of the raw milk samples were of satisfactory quality from a microbiological point of view. Campylobacter jejuni and Arcobacter butzleri were determined in the enrichment broth of three raw milk samples. A long-term monitoring of three farms revealed that individual differences in farm management practice influenced raw milk quality.

德国北部直销原奶微生物质量与安全

摘要 在德国北部农场级别的自动售货站出售的原料奶的微生物状况是根据卫生质量参数和食源性病原体的存在来确定的。为此，检查了一百一十个样品。在 36.4% 的牛奶样品中，总活菌数 (TVC) 高于 5 log cfu mL-1。检测到假单胞菌属、肠杆菌科、酵母菌和霉菌的计数平均值为 3.9 ± 1.3 log cfu mL-1、2.7 ± 1.2 log cfu mL-1、3.1 ± 0.9 log cfu mL-1 和 1.5 ± 0.8 log cfu mL-1 -1，分别。总体而言，从微生物的角度来看，只有 43% 的原料奶样本质量令人满意。在三个原料奶样品的增菌肉汤中测定了空肠弯曲杆菌和布茨勒弧菌。
