Investigation of the Presence and Levels of Aflatoxin M1 in Labneh Cheese from Different Producers in Afyonkarahisar Using ELISA

Aflatoxins are toxic compounds produced by Aspergillus species and are among the most dangerous mycotoxins. They can cause serious health effects such as cancer, birth defects, and genetic damage. Humans are mainly exposed through contaminated food and animal products like milk, dairy, and eggs. AFM1 is the metabolite of AFB1 found in milk and dairy products resulting from the consumption of contaminated feed containing AFB1 by dairy animals. In this study conducted for this purpose, the presence and level of AFM1 in labneh cheeses of different brands were investigated. In this context, 40 labneh cheese samples sold in markets were collected, and the presence of AFM1 was investigated using the ELISA method. AFM1 level was detected between 0.026-0.033 µg/kg in 10% (4/40) of the labneh cheese samples analysed. All of the samples were found below the Turkish Food Codex Contaminants Regulations limit (0.050 µg/kg). In conclusion, it is recommended to raise awareness about the potential health risks associated with the consumption of milk and dairy products contaminated with AFM1, which is an important group among Aflatoxins that harbour many health risks that may affect the general public, and to implement measures to prevent contamination in the food supply chain.
