Pilot survey of aflatoxin-albumin adducts in sera from Egypt.

Aflatoxins are potent liver carcinogens that frequently contaminate cereals in developing countries. Aflatoxin exposure has been predicted in Egypt but, to date, no studies have measured the level of aflatoxin-albumin (AF-alb) adducts as a validated biomarker to assess exposure. In this pilot survey, a limited number of sera samples, available from a hepatocellular carcinoma (HCC) case-control study in Egypt, were analysed.
