چکیده

آفلاتوکسین به‌عنوان یکی از قوی­ترین مواد سرطان‌زا تهدید جدی برای سلامت جامعه محسوب می‌شود و برنامه‌ریزی برای کاهش میزان آفلاتوکسین M1 در شیر و فراورده‌های آن بدون ارزیابی وضعیت موجود امکان‌پذیر نیست. در این بررسی میزان آفلاتوکسین در شیرهای پاستوریزه شهر تبریز اندازه‌گیری شد. 74 نمونه شیر پاستوریزه تولیدی یازده کارخانه مختلف در فصول پاییز و زمستان 93 جمع‌آوری شد. مقدار آفلاتوکسین M1 با روش الایزا اندازه‌گیری شد. 83 درصد نمونه‌ها آلودگی به آفلاتوکسین M1 در محدوده 80-5 نانوگرم در لیتر داشتند. تنها 6/12 درصد نمونه‌ها (9 نمونه) میزان آفلاتوکسین M1 بالاتر از 50 نانوگرم در لیتر بود که حداکثر مقدار مجاز تعیین ‌شده توسط اتحادیه اروپا است. براساس استاندارد کدکس، استاندارد غذا داروی آمریکا و استاندارد ملی ایران، آلودگی تمام نمونه‌ها کمتر از حد مجاز بود. در نمونه‌های شیر پاستوریزه کارخانه‌های لبنی مختلف از نظر میزان آلودگی به آفلاتوکسین M1، تفاوت معنی‌دار وجود داشت (05/0>p). پایش مداوم میزان آفلاتوکسین M1 در شیرهای توزیعی یک اقدام ضروری در کنترل و پیشگیری از این آلاینده است.

چکیده [English]

Aflatoxin, as one of the most potent carcinogen, is considered an important threat for public health, and it is not possible planning for reducing aflatoxin M1 (AFM1) levels in milk and milk products without paying great attention to the exposure to these compounds. This survey aimed to investigate the occurrence of AFM1 in pasteurized milk samples produced in Tabriz, Iran. Seventy-four milk samples produced by eleven different factories were collected from local market during six months in fall and winter 2015. AFM1 was analyzed by Enzyme-Linked Immune Sorbent Assay (ELISA). Based on results, 82% of the samples were contaminated with AFM1 in concentration levels ranged 5 to 80 ng/l. In 9 samples (12.16%) the AFM1 level was higher than 50 ng/l, the maximum residue limit (MRL) accepted by Codex and European Union for AFM1 in milk. The difference of AFM1 level between dairy factories was statistically significant (p<0.5). It seems that continuous monitoring of AFM1 contamination in distributed milk is a critical step in control and prevention of this contaminant.
