English Abstract This report describes the investigations on the
occurrence of ochratoxin A in 26 samples meat products, 2 samples porcine
blood plasma and 2 samples porcine dried plasma. The method of analysis
used, is described in the Standard Operating Protocol (SOP nr. ARO 091),
added as an annex to this report. The results of the investigations have
shown that ochratoxin A was not detectable in any of the analysed meat
products. Ochratoxin A was detectable, however, in both samples of blood
plasma and in both samples of dried plasma (concentration: 4 and 4.4 mug/kg
dried plasma ; <0.5 mug/kg blood plasma). The limit of detection of the
method of analysis used was 0.1 mug/kg (signal/noise <__3). The identity
of ochratoxin A in the samples dried plasma was confirmed with a
derivatization procedure. These results have led to the provisional
conclusion, that there is currently no reason for concern about human
exposure to ochratoxin A through consumption of meat products, sold in the
Netherlands.
