Fumonisins and zearalenone fed at low levels can persist several days in the liver of turkeys and broiler chickens after exposure to the contaminated diet was stopped

Previous studies using zearalenone (ZEN) and fumonisins (FB) revealed alpha-zearalanol (?-ZOL) FB1 in the liver of turkeys chickens with no sign toxicity. The aim present study was to determine whether contamination persists after distribution a mycotoxin-free diet for several days. Turkeys broilers were fed 14 days containing respectively, 7.5 0.6 mg/kg FB ZEN, then 0, 2 or 4 diet. total ?-ZOL most abundant metabolites found, their concentration decreased time. decrease linear (P < 0.001) exponential ?-ZOL. Mean concentrations on 2, 4.9, 4, 2.9 ng/g turkeys, 5, 2.3, 1.3 ng/g chickens. time modeled by regression (P < 0.001). 4.8, 0.8, 0.5 ng/g whereas only quantified day 0 at 0.3 ng/g. A strong correlation found between ?-zearalenol
