To investigate the frequency of occurrence and the concentrations of aflatoxins (AFs), deoxynivalenol (DON), zearalenone (ZEN) and fumonisins (FBs) in naturally infected maize, 25 samples of maize collected from fields in Hebei Province, China, were analyzed by high-performance liquid chromatography (HPLC). The maize samples were found to be frequently contaminated with DON (68%), ZEN (60%) and FBs (32%) in the range of from 28 to 2533？μg/kg, 60 to 1239？μg/kg and 150 to 4480？μg/kg, respectively. The average concentration found for DON, ZEN and FB1+ FB2 were 605, 238 and 418？μg/kg, respectively. The average concentration of DON (605？μg/kg) in our samples was below the maximum tolerable limit of 1000？μg/kg set as the Chinese standard for maize, while ZEN (238？μg/kg) was almost four times as high as the maximum tolerable limit of 60？μg/kg. The overall level of FB (FB1+ FB2) contamination was relatively low, with an average concentration of 418？μg/kg in 32% (8 of 25) of maize samples from Hebei. AFs were not detected in any of the tested samples. This is the first report on the natural occurrence of multimycotoxin in maize in China. |
