چکیده

سبزیجات از گروه‌های اصلی هرم ‌غذایی محسوب شده و مصرف آن‌ها نقش اساسی در ارتقاء سطح سلامت افراد جامعه دارد. از طرفی امروزه ابتلا به بیماری‌های میکروبی ناشی از مصرف انواع سبزی آلوده روند افزایشی پیدا کرده است. این مطالعه باهدف تعیین میزان آلودگی میکروبی‌ سبزی­های بسته‌بندی‌شده آماده مصرف در شهر مشهد انجام گرفت. در این پژوهش درمجموع تعداد200 نمونه سبزی­‌خوردن از مناطق مختلف شهر مشهد به­صورت کاملاً تصادفی جمع‌آوری و هر یک از نمونه‌ها بر اساس روش‌های مرجع و استاندارد ازلحاظ شمارش‌ مزوفیل­های هوازی، میزان آلودگی به کلی­فرم­ها، اشریشیاکولای، کپک و همچنین تخم‌ انگل مورد آزمون قرار گرفتند. نتایج حاصل از این تحقیق نشان داد میزان آلودگی به مزوفیل­های هوازی، کلی­فرم­ها، اشریشیاکولای،کپک و تخم ‌انگل به ترتیب در 19، 14، 8، 13 و 5/3 درصد نمونه‌ها بالاتر از حد مجاز بود. در مجموع 31 درصد نمونه‌های مورد آزمون به دلیل آلودگی میکروبی بیش‌ازحد غیرقابل‌مصرف گزارش شدند. در این زمینه ارائه آموزش­های لازم به تولیدکنندگان و مصرف­کنندگان سبزیجات جهت رعایت قوانین بهداشتی ضروری است، ضمن آن­که اعمال نظارت‌های پیشگیرانه دقیق‌تر از جانب سازمان‌ها و ارگان‌های ذی‌ربط نیز توصیه می­شود.

چکیده [English]

Vegetables are one of the main categories of the food pyramid and their consumption plays a vital role in the health promotion of the community. On the other hand, the incidence of microbial diseases caused by the consumption of contaminated vegetables has been increasing. The aim of this study was to determine the microbial contamination of different kinds of ready for use packaged vegetables in Mashhad, Iran. For this, a total of 200 vegetable samples were randomly collected from different regions of Mashhad. samples were examined with the standard methods in terms of the aerobic mesophilic bacteria, coliforms, Escherichia coli, moldand parasitic eggs. Results showed that in 19%, 14%, 8%, 13%, and 3.5% of the samples, the contamination rate of aerobic mesophilic bacteria, coliform, Escherichia coli, mold, and the parasitic eggs was higher than Iranian National Standard limits, respectively. In addition, a total of 31% of the samples were unusable due to excessive microbial contamination. Therefore, producers and consumers should be given the necessary training to use hygienic rules and stricter preventive measuring is also recommended.
