Abstract
This survey describes the fumonisin B 1(FB1) occurrence in 228 and 58 corn-based food samples from Spain for human and animal consumption, respectively. High-performance liquid chromatography (HPLC) with ophthaldialdehyde derivatization was used for the analysis of FB 1. We detected FB1 in 86% of the samples for animal consumption, ranging from 89–8757 ng/g. Four of these samples had levels of FB 1> 5000 ng/g but none of them higher than 10,000 ng/g. On the other hand, FB 1was detected in 23% of the samples for human consumption. The lowest amount of FB 1found in a positive sample was 16 ng/g, and the highest was 938 ng/g. The most contaminated samples were the wholemeal corn flours, with a range of contamination that varied from 299–938 ng/g.
