AFLATOXIN M1 (AFM1) Aflatoxin M1 (AFM1) is the main metabolite of aflatoxin B1, which is a mycotoxin produced by the mold species Aspergillus. It is therefore essential to take all the necessary precautions: Prevention of fungal growth on crops in the field, at harvest of crop, during storage of food and feeds. Public Health Importance High-level aflatoxin exposure produces an acute hepatic necrosis (acute aflatoxicosis), resulting later in cirrhosis or carcinoma of the liver. Oxidative stress becomes measurably elevated during STG exposure, which causes a depletion of antioxidants such as glutathione, particularly in the liver. View our Cookie Policy page.

Acceptable regulatory concentrations in milk may range from 0.05 ppb to 0.5 ppb in different countries . Aflatoxins are relatively stable to heat, and are not destroyed by boiling water, pasteurization, or autoclaving. This cookie does not track individuals. There are also differences in levels of aflatoxin M1 in milk depending on when surveys were conducted, as invariably levels are higher in winter periods, when dairy cattle are more dependant of feed rather than outside grazing. :Flush eyes, mouth, or nose for 15 minutes at an eyewash station.
