Abstract

Introduction: The use of medicinal plants has risen worldwide. In Iran, herbal waters and rose waters are of traditional medicinal products and as a result, they are widespreadly consumed. Therefore, diagnosis of microbial quality of these products is important. The aim of this study was to evaluate microbial quality of herbal extracts distributed in Kashan, Iran.

Methods: In this descriptive study, 256 samples of herbal waters and 191 samples of rose waters (total samples of 447) distributed in Kashan during 2012 to 2013 were purchased and transferred to laboratory. Then microbial tests such as total aerobic bacterial count, mold and yeast count, total coliforms, and detection of Enterococcus, Pseudomonas and sulphite-reducing Clostridia were evaluated based on national standard of Iran.

Results: Contamination with Pseudomonas and Enterococcus was observed in the herbal water samples. 196 cases (43.84%) of the total samples, 113 cases (44.15%) of the herbal waters and 83 cases (43.45%) of the rose waters were usable based on the national standard of Iran. Neither herbal waters nor rosewater samples were contaminated by E.Coli and Sulphite-reducing clostridia. Additionally, none of the rosewater samples was contaminated by Coliforms and Pseudomonas.

Conclusion: Based on the findings and due to the fact that these products are contaminated with aerobic mesophilic bacteria, mold and yeast, to minimize the risks we recommend to apply pasteurized temperature, high-quality packaging material and hygiene observance in processing time of herbal waters and rose waters.

Keywords: Herbal waters, E. coli, Clostridia, Enterococcus, Pseudomonas

Implication for health policy/practice/research/medical education:

The herbal products such as the ones distributed in Kashan might be contaminated with aerobic mesophilic bacteria, mold and yeast, therefore, it is suggested that manufacturers of herbal waters pay attention to the hygiene observance, Good Hygiene Practice, the use of pasteurization temperatures, observance of condition of the manufactory and appropriate packaging in the manufacturing processes to reduce secondary contamination and enhance the quality of the final product.
