Characterization of Serum and Urinary Zearalenone and its Metabolites (Z) and its Association with Dietary Intake

The environmental estrogen, zearalenone (ZEA), is found in the food supply from Fusarium contamination in grains and zeranol is sometimes used as a growth promoter in beef cattle. Circulating concentrations of Z metabolites [ZEA, a‐zearalenol, zeranol, b‐zearalenol, b‐zearalanol and zearalanone] have not been previously examined in adults and could have an estrogenic effect. Our goal was to characterize the free and total Z metabolite...
