Dietary supplements, particularly those containing ingredients of natural origin, may contain microbiological contaminants, both bacterial and fungal. The present study evaluated the microbiological purity of selected dietary supplements containing plant-based ingredients before their release to the market, as well as raw materials of plant origin which are used in the production of such supplements. A total of 122 samples of supplements and 30 materials of plant origin were studied, with 92.1% exhibiting different degrees of bacterial contamination. Eight samples (5.3%) were contaminated by aerobic bacteria in amounts exceeding 10 CFU/g. Five (3.3%) of the studied supplements were found to contain bacteria from the family at a level exceeding 10 CFU/g. Furthermore, a considerable proportion of the studied samples (86.8%) contained fungal contamination. Microbiological contamination may contribute to a deterioration in quality and stability of dietary supplements. In addition, high levels of pathogenic bacteria and microorganisms may pose a risk to consumers.
膳食补充剂，尤其是那些含有天然来源成分的产品，可能含有细菌和真菌等微生物污染物。本研究评估了选定的含有植物性成分的膳食补充剂在投放市场之前的微生物纯度，以及用于生产此类补充剂的植物源性原材料。共研究了122份补充剂样品和30份植物源性材料，其中92.1%表现出不同程度的细菌污染。8个样品（5.3%）被需氧菌污染，污染量超过10 CFU/g。在所研究的补充剂中，有5份（3.3%）被发现含有肠杆菌科细菌，含量超过10 CFU/g。此外，相当一部分研究样品（86.8%）含有真菌污染。微生物污染可能会导致膳食补充剂的质量和稳定性下降。此外，高水平的病原菌和微生物可能会对消费者构成风险。
