Determination of AFM1 Levels of Mare’s Milk and Koumiss Produced in the Highlands of the Kyrgyz Republic

Mare’s milk and koumiss are two very important basic foodstuff s in central Asia.This study aimed to research the AFM1 contamination in mare’s milk and koumiss samples collected from local producers in the highlands in Naryn, Issyk-Kul, Bishkek and Talas regions of Kyrgyz Republic. For this purpose, 75 raw mare’s milk and 75 koumiss samples collected in May, June and July 2017 were analyzed using the ELISA method. AFM1 was detected in 13.3% of the 75 raw mare’s milk samples with levels ranging between 6.48 and 25.45 ng/L. Approximately 53.3% of the koumiss samples were found to contain AFM1, with levels ranging between 5.93 and 18.77 ng/L. None of the AFM1 levels in the tested samples exceeded above the 50 ng/L maximum limit set by the European Union for milk and the 500 ng/kg limit set by Kyrgyz Republic. As the levels of AFM1 in the raw mare’s milk and koumiss were low, it can be said that these products do not pose a serious risk in terms of public health. This study has been an important source for determining AFM1 levels in mare’s milk and koumiss.

Kırgızistan Yaylalarında Üretilen Kısrak Sütü ve Kımız’ın AFM1 Seviyelerinin Belirlenmesi

Kısrak sütü ve kımız, Orta Asya’da çok önemli iki temel gıda maddesidir. Bu çalışma, Kırgızistan’ın Narın, İssyk-Kul, Bişkek ve Talas bölgelerindeki yerel üreticilerden toplanan kısrak sütü ve kımız örneklerinde AFM1 kontaminasyonunu belirlemek amacıyla yapılmıştır. Bu amaçla Mayıs, Haziran ve Temmuz 2017’de toplanan 75 çiğ kısrak sütü ve 75 kımız numunesi ELISA yöntemi kullanılarak analiz edilmiştir. AFM1, 6.48 ile 25.45 ng/L arasında değişen seviyelerde 75 çiğ kısrak süt numunesinin %13.3’ünde tespit edilmiştir. Kımız numunelerinin yaklaşık %53.3’ünün AFM1 içerdiği bulunmuştur ve seviyeleri 5.93 ile 18.77 ng/L arasında değişmiştir. Test edilen numunelerdeki AFM1 seviyelerinin hiçbiri, Avrupa Birliği tarafından süt için belirlenen 50 ng/L maksimum sınırı ve Kırgıziztan tarafından belirlenen 500 ng/kg sınırını aşmadı. Çiğ kısrak sütü ve kımızdaki AFM1 seviyeleri düşük olduğu için bu ürünlerin halk sağlığı açısından ciddi bir risk oluşturmadığı söylenebilir. Bu çalışma kısrak sütü ve kımızdaki AFM1 seviyelerini belirlemesi bakımından önemli bir kaynak olmuştur.
