All shipments of Iranian pistachio nuts to the USA must be inspected for aflatoxin contamination and at irregular intervals some of them are rejected. The only point-of-origin climatic factors correlated with rejections were rainfall and number of calm days per month from August through November, the period of ripening and harvest. These conclusions support those of previous studies.
