title: A survey using normal-phase high-performance liquid chromatography of aflatoxins in domestic and imported foods in the USSR.
abstract: A survey of the occurrence of aflatoxins B1, B2, G1 and G2 in Soviet domestic and imported cereals and nuts (totalling 4532 samples) collected in 1985-87, showed that 26.9% of imported peanuts, 2.2% of corn and 28.3% of cotton seeds were contaminated by aflatoxins at levels exceeding the maximum tolerated level established in the USSR (5 micrograms/kg for aflatoxin B1 in foodstuffs of all types excluding baby foods); maximum concentrations were 3650, 600 and 153 micrograms/kg, respectively. A highly sensitive normal-phase high-performance liquid chromatographic method was developed. The detection limit was 0.1 microgram/kg and the coefficients of variation were 11% and 8.5% at contamination levels 10 and 100 micrograms/kg of aflatoxin B1, respectively.
