Bongkrek acid is a respiratory toxin more deadly than cyanide.[1]

It is produced in fermented coconut contaminated by the bacterium Burkholderia gladioli pathovar cocovenenans. In particular, it has been implicated in deaths resulting from eating the soybean and coconut-based product known as tempe bongkrèk , which is banned in Indonesia.

It is highly toxic because of its effect on the ATP-ADP translocase mechanism. It shuts this system down, preventing ATP from leaving the mitochondria and providing energy to the rest of the cell.
