Sixty-two samples of maize imported in The Netherlands and intended fo
r human consumption were screened for the presence and concentration o
f fumonisin B-1. Sixty-one of those samples contained fumonisin B-1 wi
th concentrations ranging from 30 to 3350 mu g kg(-1), 11 maize sample
s contained > 1000 mu g kg(-1). The average fumonisin Br concentration
was 640 mu g kg(-1) for the positive samples and 620 mu g kg(-1) for
all samples. Medians were 600 mu g kg(-1) and 550 mu g kg(-1) for posi
tive and all samples, respectively. The results obtained were comparab
le to results from other studies in maize from various countries.
