Analysis of Mycotoxins from Biological Fluids in Bovids

Violeta-Elena SIMION

Abstract


The consumption of feeds contaminated with mycotoxins (particularly aflatoxins,
ochratoxin A, zearalenone) by the animals causes various hepatic and renal; disorders, severe
immunodeficiency, reproductive disorders and the presence of these mycotoxins or their metabolites in
various fluids (such as aflatoxin M1, metabolite of aflatoxin B1). Various studies have determined the
presence of aflatoxin M1 and of zearalenone in milk, of aflatoxin B1 in the hepatic tissue and in the
serum, of ochratoxin A in the liver, of zearalenone in the bile; the presence of these mycotoxins in
different organs depends on the selective place of metabolisation of these mycotoxins. The research
aimed to determine the aflatoxins (AFB1, AFB2 and AFM1), ochratoxin (OTA) and zearalenone (ZEA)
in some biological fluids (milk, ruminal fluid, urine and bile) collected from bovids (cows and sheep),
using ELISA and CSS techniques. The results have shown the presence of mycotoxin metabolites in all
the analysed matrices, with values between 0 (below the detection limit) and 2.23 ppb for total AF in the
ruminal fluid; 25.06 ppb for OTA in the ruminal fluid; 42 ppt for AFM1 in milk and absence of
mycotoxins AFB1, AFB2 and ZEA in the samples of urine and bile.
