摘要:
This survey examined 140 samples of raw maize as received at ports or at major maize mills in the UK and 12 after initial cleaning. Samples were examined for aflatoxins B1, B2, G1and G2, ochratoxin A, zearalenone and fumonisins B1, B2and B3using fully validated analytical HPL C methods with detection limits of 0.1 μg/kg for each aflatoxin and ochratoxin A, 4 μg/ kg for zearalenone and 10 μg/kg for each fumonisin. 95.0% and 92.1% of samples met the new EC statutory maximum permissible level for total aflatoxins and aflatoxin B1respectively. The maximum concentration of ochratoxin A found was 1.5 μg/kg. Zearalenone and fumonisins were detected in almost every sample with 41.7% of maize containing more than 100 μg/kg of zearalenone and 48% of samples containing more than 1000 μg/kg total fumonisins. Initial cleaning of raw maize reduced aflatoxin concentrations by about 40% and total fumonisins by 32%.
