title: Short communication: investigation of aflatoxin M1 levels in infant follow-on milks and infant formulas sold in the markets of Ankara, Turkey.
abstract: Aflatoxins are fungal toxins known to be carcinogenic and are classified as food contaminants. This study was performed to investigate aflatoxin (AF) M1 levels in baby foods sold in Ankara (Turkey) and to evaluate the obtained results according to the Turkish Food Codex (TFC). For this purpose, a total of 84 baby food samples (50 follow-on milks and 34 infant formulas) were obtained from different markets in Ankara and the presence of AFM1 in the samples was analyzed by ELISA. In 32 (38.1%) of 84 infant food samples, the presence of AFM1 was detected in concentrations ranging between 0.0055 and 0.0201 µg/kg. The mean level (± standard error) of AFM1 was found to be 0.0089 ± 0.0006 µg/kg in positive infant follow-on milks. Aflatoxin M1 was detected in only 1 infant formula sample (2.94%) at a concentration of 0.0061 µg/kg. The extrapolated levels of AFB1 contamination in feedstuffs were calculated based on levels of AFM1 in baby food samples. The data estimating AFB1 contamination in dairy cattle feedstuff indicate that contamination may range from 0.3410 to 1.2580 µg/kg, with the mean level (± standard error) being 0.5499 ± 0.0385 µg/kg, which is lower than the level set by the TFC and European Union regulations (5 µg/kg). According to the obtained results, the levels of AFM1 in analyzed samples were within the allowed limit (0.025 µg/kg) set in the TFC. Low levels of AFM1 in infant follow-on milks and infant formula samples obtained during the study do not pose a health risk to infants.
