Aluminium Phosphide is a solid fumigant bulk grain preservative and is available in the market under various trade names like Celphos, Quickphos, Phostoxin, Phostek, Gastoxin, Zedesa, Li Fumesets. It is marketed either in Tablet or pellet form. Mortality is high as mechanism of action is not clearly understood and no specific antidote is available against this poison. Samples of tissues fromliver, lungs, kidneys and spleen were preserved in 10% Formal Saline, processed for histopathology, stained by HaematoxylinandEosin method and studied microscopically.
