Samples of organic cow's milk, conventional cow's milk, and cow's milk-base
d infant formulas were analysed for the occurrence of ochratoxin A by means
of an HPLC method. The detection limit was 10 ng/l. Ochratoxin A was detec
ted in 6 out of 40 conventional cow's milk samples (range 11-58 ng/l), and
in 5 out of 47 organic milk samples (range 15-28 ng/l). No ochratoxin A,vas
detected in any of the 20 infant formula samples. The ochratoxin A levels
in cow's milk found in this investigation are sufficient to cause a higher
intake of ochratoxin A than the suggested TDI of 5 ng/kg bw/day, e.g. in sm
all children who consume large quantities of milk.
