A considerable amount of research examines the percent carry-over from aflatoxin B1 (AFB1) to aflatoxin M1 (AFM1) in feed as a result of sequestering binders. However, relatively few studies have been conducted as a result of AFM1 contamination in raw milk after pasteurization. This study examined the proficiency of adsorbents, activated carbon (AC) and Mycofix, to bind AFM1 in raw, pasteurized skim, and whole milks. A total of 24 milk samples (r=3) contained adsorbents and/or artificially spiked AFM1 (70 ppb). Samples were shaken and extracted using Agilent QuEChERS extraction salts and analyzed. Fat, protein, and lactose were also analyzed. AC (0.25%-2%) resulted in a significant decrease in AFM1 contamination (p<0.05) with a reduction of 75.2% to 94.7%. Mycofix did not show significant reductions of AFM1 contamination. A reasonably high reduction of contaminated samples suggests that the use of AC can reduce the amount of AFM1 to the FDA safety limit.
