Bongkrek acid (also known as bongkrekic acid[1]) is a respiratory toxin produced in fermented coconut or corn contaminated by the bacterium Burkholderia gladioli pathovar cocovenenans.[2][3][4]

It is highly toxic because the compound inhibits the ADP/ATP translocase, also called the mitochondrial ADP/ATP carrier, preventing ATP from leaving the mitochondria to provide metabolic energy to the rest of the cell.[5] The structure of bongkrekic acid bound to ADP/ATP translocase was solved in 2019, demonstrating that it binds to the substrate binding site, preventing ATP in the mitochondrial matrix from binding.[6]

It has been implicated in deaths resulting from eating the coconut-based product known as tempe bongkrèk, which is banned in Indonesia.[7] It was also responsible for 75 deaths and over 200 hospitalizations due to contaminated beer in a Mozambique funeral. In October 2020, nine members of a family in China died after eating corn noodles contaminated with the acid.[8]
