Abstract

The aflatoxin (AF) albumin adduct is often used as a biomarker for aflatoxin exposure in humans. An ELISA method previously used for aflatoxin serum albumin in human blood was used to analyse bovine serum samples (n = 22) collected from dairy cattle during an aflatoxin mitigation study in Kenya. Albumin adduct data were compared with aflatoxin M-1 (AFM(1)) levels in corresponding milk samples from these cows. The concentration ranged from < LOD to 487.9 pg/mL for AFM(1) and < LOD and 96.3 pg/mg for aflatoxin-albumin. This study indicates that aflatoxin-albumin adducts could be used as a measure of chronic aflatoxin exposure in dairy cattle.
