Contamination of tree nuts by aflatoxigenic fungi: aflatoxin content of closed – shell pistachios.

Inoculation of fresh, or dried and rehydrated, closed – shelf pistachios at the stem end of the shell with spores of Aspergillus flavus resulted in aflatoxin contamination of the kernel after incubation. The proportion of contaminated nuts was 48% for the fresh pistachios and 35% for the dried pistachios. Closed – shell pistachios batch – rehydrated for 3 hr in a bath inoculated with A.flavus spores showed aflatoxin levels in the kernels of 170 mg/kg after 2 days incubation and 87500mg/kg after 6 days. This study demonstrates that the kernels of closed – shell pistachios can be contaminated with aflatoxin, probably through penetration of the stem end of the shell by Aspergillus species, and the practice of rehydration prior to mechanical splitting should therefore be avoided.
