A survey of aflatoxin levels in peanut meal imported into Poland for animal feedingstuffs.

Peanut meals (366 samples) imported into Poland from Brazil and India during 1984-86 for use in animal feedingstuffs were analysed for aflatoxins B1 and B2. Average levels of contamination were 71 micrograms per kg for aflatoxin B1 and 16 micrograms per kg for aflatoxin B2 with total concentrations ranging from 2 to 750 micrograms per kg.

Levels of aflatoxin B1, bacteria and fungi in feed and food in 1971 - 1987.

Totally 39% out of 8371 feed and their component samples were contaminated by aflatoxin B1. Mean contamination was 36µg/kg with maximum yield 10100 µg/kg. Contamination of samples by total count of organisms, mean contamination and maximum yield, respectively was: 1) bacteria 99%, 2.2×10(6), 2.4×10(8); 2) proteolytic bacteria 94%, 1.2×10(5), 3.0×10(6);3) moulds 98%, 1.3×10(5), 9.0×10(6); 4) yeasts 44 %, 3.3×10(4), 3.6×10(6). The samples were contaminated in 92 % byAspergillus spp, in 71% byAspergillus flavus, in 83% byPenicillium spp, and in 20% byFusarium spp with mean contamination 8.3×104, 1.1×10(3), 4.2×10(4), 5.0×10(3) , and maximum yield 6.8×10(6), 1.0×10(5), 5.0×10(6), 1.5×10(6), respectively. Totally 8.5% of strains were aflatoxinogenic and 4.4% of the strains were isolated from feed and 21 % of the strains from grain/nut.
