Determining the aflatoxin M1 levels in breast milk

OBJECTIVE: Mycotoxins are different toxic substances at relatively smaller molecular weight produced by some types of fungi. Aflatoxin is the most common type of mycotoxin easily reproducing in food stored for a long time in unsuitable conditions. This study determined the aflatoxin M1 (AFM1) levels in breast milk samples collected from mothers who gave birth in Kirsehir, Turkey. MATERIALS AND METHODS: A total of 82 breast milk samples to be analyzed to determine the AFM1 levels were collected from voluntary breastfeeding mothers who gave birth in the Kirsehir Training and Research Hospital and who were randomly selected. The AFM1 levels were determined using the competitive ELISA kit. RESULTS: The AFM1 levels in the breast milk samples of mothers who did not consume milk were lower than those of other mothers. The AFM1 levels in the breast milk samples of mothers consuming fabrication milk were lower than mothers consuming homemade milk (p<0.01). Additionally, the AFM1 levels in the breast milk samples of mothers consuming homemade or self-made bread were lower (p<0.05). CONCLUSIONS: This study found that the nutritional habits of breastfeeding mothers affected the AFM1 levels in breast milk.
