A preliminary extraction using Zn(OH)2 precipitation is followed by hexane clean-up. Subsequently a vacuum concentrated chloroform extract is injected on to a C18 grafted silica column and eluted with acetonitrile:methanol:water (20:5:75). The method is accurate and reliable, giving a recovery of approx. 80% and, through an efficient clean-up of the milk sample, allows rapid determination of aflatoxin M1 with a detection limit of 10 ng/l milk.
