One stage of honey production is extraction. Honey is a product with minimal types and levels of microorganisms; however it could be contaminated during its manipulation. The aim of this work was to evaluate the microbiological contamination of honey at different processing points. Mould and yeast, total coliform number as well as the presence of Salmonella spp. were determined in 50 samples. All comb and centrifugal honey-extractor samples showed low levels of mould and yeast (< or = 10 CFU/g of honey) and an absence of total coliforms. Contamination problems were observed at the uncapping stage of beeswax-capped honey separation, showing that the "unheated" honey process would imply more risks. Ten to fifty CFU/g of honey of mould and yeast were observed in four out of 30 samples from the honey pump and drums. The present work shows the importance of preventing contamination at the beeswax-honey separation stage, and also highlights the need to perform microbiological studies in the honeyhouse, which would contribute to determine critical points in control quality systems.
蜂蜜生产的一个阶段是提取。蜂蜜是一种微生物种类和含量极少的产品;然而,在加工过程中它可能会被污染。这项工作的目的是评估蜂蜜在不同加工点的微生物污染情况。对50个样本测定了霉菌和酵母菌、总大肠菌群数量以及沙门氏菌属的存在情况。所有蜂巢和离心式蜂蜜提取器样本显示霉菌和酵母菌含量较低(≤10 CFU/g蜂蜜)且无总大肠菌群。在分离封盖蜂蜜的开盖阶段观察到了污染问题,表明“未加热”的蜂蜜加工过程意味着更多风险。在蜂蜜泵和储存罐的30个样本中有4个样本观察到蜂蜜中霉菌和酵母菌含量为10至50 CFU/g。本研究表明了在蜂蜡 - 蜂蜜分离阶段防止污染的重要性,同时也强调了在蜂蜜加工车间进行微生物研究的必要性,这将有助于确定质量控制体系中的关键点。
