Fumonisin B1 (FB1) and fumonisin B2 (FB2) were determined in milk by liquid chromatography (LC) following immunoaffinity column cleanup. Recoveries from milk spiked with 5-50 ng each fumonisin/ml averaged 79-109%. The aminopentol hydrolysis product of FB1 (AP1) was determined by LC after cleanup on a C18solid phase phase extraction column; mean recoveries were 69-83% at spiking levels of 50-100 ng AP1/ml milk. Detection limits were of the order 3-7 ng/ml for FB1 and FB2, and 20-25 ng/ml for AP1. A stability study showed no losses of FB1 and FB2 in milk under conditions of freezing, refrigeration and boiling. A transmission study using four cows dosed with pure FB1, either orally (1.0 and 5.0 mg FB1/kg b.w.) or by i.v. injection (0.05 and 0.20 mg FB1/kg b.w.) showed no detectable residues of FB, or AP1 in the milk, with or without hydroiytic treatment with β-glucuronidase/sulfatase to liberate any conjugates. |
