Since AFlvL levels were found to be significantly high in the raw milk samples collected in Mersin province (located on Mediterranean part of Turkey), it was concluded that people dealing with feed, milk and dairy products should be informed about the importance of aflatoxins and the preventive measures to get protected from AFB1 and AFMr

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aflatoxin M1 (AFM,) which is produced by some Aspergillus species, mainly Aspergillus flavus, is the hydroxylated metabolite of aflatoxin B1 (AFB.,) and can be found in milk and dairy products of livestock fed with contaminated feed.
📊
Key Findings & Data:AFM1 is a potential threat to human health owing to its toxic and carcino- qenic effects.
💡

Abstract

Aflatoxin M1 (AFM,) which is produced by some Aspergillus species, mainly Aspergillus flavus, is the hydroxylated metabolite of aflatoxin B1 (AFB.,) and can be found in milk and dairy products of livestock fed with contaminated feed. AFM1 is a potential threat to human health owing to its toxic and carcino- qenic effects. This study was aimed to investigate the level of AFM1 in raw and ultra-high-temperature pasteurized (UHT) milk samples. A total of 137 milk specimens (39 from goats, 53 from cows, and 45 from UHT market milks) were included to the study, and AFM1 levels were analyzed by high performance liquid chromatography (HPLC; Aflaprep M immunoaffinity column; R-Biopharm Rhone Ltd., Glasgow) method. AFM1 positivity was detected in 14 (35.8%) goat milk samples, in 46 (86.7%) cow milk samples and 33 (73.3%) UHT milk samples, with the levels ranging from 0.0021 ug/l to 0.8666 ug/l in raw milk, and from 0.001 ug/l to 0.059 ug/l in UHT milk samples. In 10.2% (4/39) of goat milk, 73.5% (39/53) of cow milk, and 2.2% (1/45) of UHT milk samples, the toxin levels were found to be above the officially.reasonable limit value (> 0.05 ug/l) recommended by Turkish Food Codex Regulation. Since AFlvL levels were found to be significantly high in the raw milk samples collected in Mersin province (located on Mediterranean part of Turkey), it was concluded that people dealing with feed, milk and dairy products should be informed about the importance of aflatoxins and the preventive measures to get protected from AFB1 and AFMr

Özet

Aflatoksin Mı (AFlvl.,), başta Aspergillus flavus olmak üzere bazı Aspergillus türleri tarafından üretilen aflatoksin Bı (AFB^'in hidroksillenmiş bir metaboliti olup, kontamine yemlerle beslenen çiftlik hayvanlarının süt ve süt ürünlerinde bulunabilir. İnsanlar için en temel besin kaynağı olan süt ve süt ürünlerinde bulunabilecek AFM1, toksik ve karsinojenik etkileri nedeniyle insan sağlığı için potansiyel bir risk oluşturmaktadır. Bu çalışmada, ilimizdeki çiğ ve market sütlerindeki AFM1 düzeyinin araştırılması amaçlanmıştır. Çalışmaya, 39 keçi ve 53 inekten alınan toplam 92 çiğ süt örneği ile marketlerden rastgele alınan üretim tarihleri ve üretici firmaları farklı 45 adet UHT (ultra high temperature) ile pastörize edilmiş süt Örnekleri dahil edilmiştir. Toplam 137 süt örneğinde AFM1 düzeyi, yüksek performanslı sıvı kromatografi (HPLC; Aflaprep M immunoaffinity column; R-Biopharm Rhone Ltd., Glasgow) yöntemi ile araştırılmış ve keçi sütlerinin %35.8 (14/39)'inde, inek sütlerinin %86.7 (46/53)'sinde ve UHT sütlerin %73.3 (33/45)'ünde AFM1 pozitifliği tespit edilmiştir. AFM1 düzeylerinin; çiğ sütlerde 0.0021-0.8666 ug/l, UHT sütlerde ise 0.001-0.059 ug/l arasında değiştiği izlenmiştir. Yapılan değerlendirmede; keçi sütlerinin %10.2 (4/39)'sinde, inek sütlerinin %73.5 (39/53)'inde, UHT sütlerin ise %2.2 (1/45)'sinde saptanan AFM1 düzeylerinin, Türk Gıda Kodeksi Yönetmeliğine göre kabul edilebilir aflatoksin sınır değerinin üzerinde (> 0.05 ug/l) olduğu görülmüştür. Sonuç olarak çalışmamızda, Mersin ilinden toplanan tüm süt örneklerinin %32 (44/137)'sinde sınır değerin üzerinde saptanan AFM1 varlığı; hayvan yemleri ve süt/süt ürünleri alanında faaliyet gösteren kurum ve kişilerin, aflatoksinlerin önemi ve korunma yolları konusunda hassasiyetle bilinçlendirilmesi gerektiğini düşündürmüştür.
