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 a highly toxic, heat-stable, colorless, odorless, and highly unsaturated tricarboxylic acid that 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.[4][5] Bongkrek acid, when consumed through contaminated foods, mainly targets the liver, brain, and kidneys along with symptoms that include vomiting, diarrhea, urinary retention, abdominal pain, and excessive sweating.[4] Most of the outbreaks are found in Indonesia and China where fermented coconut and corn-based foods are consumed.
