Ochratoxin A (OA) levels were measured in blood serum of mothers, fetuses and in mothers' milk [Poland]. The mean concentration of OA in maternal serum was 1.14 ng/ml and in umbilical cord blood serum, it was 1.96 ng/ml. The mean ratio of OA concentrations in maternal and fetal blood serum was 1.96. In maternal milk OA was found in 5 out of 13 studied samples. The mean intake of OA with mother's milk was not exceeding the tolerable daily intake for adults, nevertheless it was near 60% of TDI. The OA concentration ratio in maternal blood serum versus that in milk was 0.0058 on average. These results confirm the correlation between OA concentration maternal and fetal blood serum, and between OA concentration in maternal serum and milk.
