Tıbbi Bitki Çaylarında Mikrobiyolojik Kalitenin ve Bazı Patojenlerin Araştırılması

Tıbbi bitki çayları sağlık üzerine olumlu etkilerinden dolayı her yaş grubu tarafından tüketilmektedir. Bu çalışmada ambalajlı ve ambalajsız olarak perakende satışa sunulan farklı tıbbi bitki çaylarının (kekik, nane, rezene, adaçayı, ıhlamur, hatmi, sinameki, defne, civanperçemi ve anason) mikrobiyolojik kalitesinin belirlenmesi amaçlandı. Analiz edilen 120 örneğin %95, %90, %77.5, %74.16, %42.5, %14.17, %3.33 ve %2.5’inin sırasıyla toplam mezofilik aerobik bakteriler (TMAB), küf-maya, Enterobacteriaceae, koliform, sülfit indirgeyen anaerob bakteriler, Staphylococcus-Micrococcus spp., Escherichia coli ve Salmonella spp. ile kontamine olduğu belirlendi. Ancak örneklerin hiçbirinde Staphylococcus aureus ve Bacillus cereus tespit edilmedi. En yüksek ortalama TMAB (5.03 log10 kob/g) sayısı nane örneklerinde; Enterobacteriaceae (4.19 log10 kob/g), koliform (3.87 log10 kob/g) ve küf-maya sayısı (4.92 log10 kob/g) ise hatmi örneklerinde bulundu. Kapalı ambalajlarda satışa sunulan örneklerdeki ortalama Enterobacteriaceae ve koliform bakteri sayıları açıkta satışa sunulan örneklerden önemli derecede daha düşük bulundu (P

Investigation of Microbiological Quality and Some Pathogens in Medicinal Herbal Teas

Medicinal herbal teas are consumed by all age groups for beneficial effects on health. In this study, it was aimed to determine the microbiological quality in packaged and unpackaged different medicinal herbal teas (thyme, mint, fennel, sage, linden, alcea, senna, laurel, yarrow and anise) sold at retail. Out of the 120 analysed samples, 95%, 90%, 77.5%, 74.16%, 42.5%, 14.17%, 3.33% and 2.5% were contaminated with total mesophilic aerobic bacteria (TMAB), mold-yeast, Enterobacteriaceae, coliform, sulphide reducing anaerobe bacteria, Staphylococcus-Micrococcus spp., Escherichia coli and Salmonella spp., respectively. However, Staphylococcus aureus and Bacillus cereus were not detected in any of the samples. The highest mean count was determined in mint samples for TMAB (5.03 log10 cfu/g); in alcea samples for Enterobacteriaceae (4.19 log10 cfu/g), coliform (3.87 log10 cfu/g) and yeast-mold (4.92 log10 cfu/g). The mean counts of Enterobacteriaceae and coliform in packaged samples were significantly less than unpackaged samples (P
