Abstract: | The aim of the study was to estimate occurrence of ochratoxin A (OA) in feeds and the metabolite residues in porcine blood
serum in Poland. Samples were collected in the period from February to May, 1999, in the southern Wielkopolska region. Altogether
40 and 45 samples of feed and porcine blood serum, respectively, were analyzed for OA. Percentage of samples contaminated
with OA, both in case of feeds and blood, collected in the winter season was considerably higher than that for the spring
season. The percentages for feeds were as follows: 47.6 and 26.3 %, while for porcine serum: 66.7 and 50.0 %, respectively
winter and spring. In 25 % of cases ochratoxin A was present in both types of investigated material (feed, blood), whereas
in 27.5 % of samples this metabolite was detected in blood only, or in 7.5 % only in the feed. The presence of OA was found
neither in the feed nor in the serum in 40 % of all cases. In subgroups (feed, blood) the concentration in the whole collective
of positive samples were in the range 0.3–13.5 ng/g and 0.3–69.5 ng/ml, respectively, while median values were 2.3 ng/g and
6.0 ng/ml. Only one feed and three porcine serum samples, were found to be contaminated at concentration levels higher than
10 ng/g or 10 ng/ml. |
