Did you know that Pistachio nuts can self combust?
"Pistachio nuts, especially pistachio kernels, should not be stowed together with fibers/fibrous materials as oil-soaked fibers may promote self-heating/spontaneous combustion of the cargo.
As a basic principle, a high oil content (especially in pistachio kernels) encourages the tendency to self-heating.
Fat decomposition in pistachio nuts leads to the risk of self-heating and, ultimately, to a cargo fire.
