چکیده

یکی از حوزه‌های پدافند زیستی، حوزه تهدیدات دام و طیور است و ارزیابی مخاطرات میکروب‌های بیماری‌زا منتقل‌شده از مواد غذایی ازجمله سالمونلا، دارای اهمیت بالایی است. گوشت مرغ، فرآورده مناسبی برای انتقال آلودگی این بیماری به مصرف‌کنندگان بوده و به‌عنوان مخزن سالمونلا محسوب می‌شود. هدف از این مطالعه، کاهش آلودگی سالمونلایی در لاشه‌های طیور بود که با تغییر در تولید و فراوری اتفاق افتاد. در این مطالعه طی سال‌های 1393-1396، از 383 قطعه طیور، به‌صورت تصادفی نمونه‌گیری شد. پس از مراحل خالص‌سازی و جداسازی کشت‌های مشکوک، سالمونلاهای جداشده به‌وسیله آزمایش‌های بیوشیمیایی، سرولوژیکی وPCR  تائید شدند. از مجموع نمونه‌ها، تعداد 15مورد، ازنظر آلودگی به سالمونلا مثبت بودند. با اعمال دستورالعمل‌های سازمان دامپزشکی کشور، میزان آلودگی به شدت کاهش یافت.کاهش آلودگی‌های سالمونلایی، در قطعه‌های طیور، ناشی از کنترل بهداشتی، بسته‌بندی و شناسنامه‌دار کردن لاشه مرغ‌ها در کشتارگاه‌های صنعتی است. عدم رعایت عمدی و غیرعمدی مباحث بهداشتی در زنجیره تولید تا مصرف مرغ‌ها خسارت جبران‌ناپذیری را تحمیل خواهد نمود.

چکیده [English]

One of the areas of biological defense is livestock and poultry threats and assessing the health risks of foodborne germs, including Salmonella, is of great importance in many aspects. Chicken meat is a good product for the transmission of this infection to consumers and is considered as a salmonella reservoir. The aim of this study is to reduce salmonella contamination in poultry carcasses which happened with the change in production and processing. In a study during 2014-2017, 383 pieces of poultry were randomly sampled. After the stages of purification and isolation of suspicious cultures, isolated Salmonella were confirmed by biochemical, serological and PCR tests. With using PCR method, 15 samples were positive for Salmonella. By applying the Instructions of the country's veterinary organization, the rate of polution has fallen sharply. Reducing salmonella contamination in poultry pieces is due to health control, packaging and identification of chicken carcasses in industrial slaughterhouses. Intentional and unintentional nonconformity with health issues in the production chain to chicken consumption will impose irreparable damage.
