Abstract

This study included 200 samples of raw bulk milk and other dairy products (White soft cheese and Fruit yoghurt) were collected from May 2019 to June 2020, at random from Kuwait dairy farms and supermarkets and divided into 100 farm bulk milk samples and 50 samples each of soft cheese and fruit yoghurt; All of the samples were transferred to the lab in ice packs and kept at -20 0C until they were analysed. Using high-performance liquid chromatography (HPLC), the samples were tested for aflatoxin M1 (AFM1) quantification. In the current study, the mean value of aflatoxin M1 (μg/kg) for farm bulk milk, white soft cheese and fruit yoghurt samples were 0.017965, 0.074633 and 0.05398 respectively. The prevalence of aflatoxin M1 (μg/kg) for Farm bulk milk, White soft cheese and Fruit yoghurt samples above EC limit in European Union was 13, 26 and 34 % respectively. The regulatory limit for aflatoxin M1 (μg/kg) in European Union (EU) is ≤0.05 mg/kg for milk and milk products samples. The prevalence of aflatoxin M1 (μg/kg) for Farm bulk milk, White soft cheese and Fruit yoghurt samples above EC limit in USA were 0, 2 and 0 % respectively. The regulatory limit for aflatoxin M1 (μg/kg) in USA is ≤0.5 mg/kg for milk and milk products samples. The presence of AFM1 residues in contaminated milk and dairy products described in this study should emphasise the necessity of ensuring good practices in the milk and dairy production. Collectively, Milk producers and processors should be made aware of the prevalence of AFM1, its causes, and how to prevent it. Milk producers and processors should be made aware of the prevalence of AFM1, as well as its origins, implications, and strategies to prevent it from entering milk. Decontamination of AFM1 is still an open question, and further research is needed to understand the process of AFM1 binding to microbial cells, as well as the genetic properties of the bacteria involved in binding and the stability of the complex produced.
