FOOD POISONING After bongkrek acid caused the death of two people, tests found that Burkholderia gladioli bacteria, which produces bongkrek acid, is not in Taiwan

Acting Minister of Agriculture Chen Junne-jih (陳駿季) yesterday said long-term observation of plant and soil ecology suggests that a subspecies of Burkholderia gladioli bacteria, which causes bongkrek acid poisoning, does not exist in Taiwan.
The Ministry of Health and Welfare on Friday evening announced that forensics testing of two deaths and blood testing of six hospitalized people, who had eaten at a Polam Kopitam (寶林茶室) restaurant in Taipei before experiencing severe food poisoning, were found to have bongkrek acid in their blood.
Bongkrek acid is a deadly toxin produced in food, especially fermented coconut or corn, that is contaminated by one of the subspecies of Burkholderia gladioli, called Burkholderia gladioli pathovar cocovenenans (BGC), and has also been found in spoiled or fermented flour and rice-related items, as well as spoiled white or black fungus.
As nearly all of the 28 people who fell ill after eating at the Taipei restaurant chain between March 19 and Sunday last week had eaten stir-fried flat rice noodles, many people are concerned that there might be a risk of bongkrek acid poisoning from eating locally produced rice.
Chen yesterday said that he had asked specialists at the Taiwan Agricultural Research Institute to check if the bacteria have been found in soil in Taiwan, and they told him that Burkholderia gladioli bacteria have four subspecies, and only the BGC subspecies produces bongkrek acid.
They also told him long-term observation of plant and soil ecology in Taiwan suggests that while the other three subspecies have been detected, the BGC subspecies does not exist in Taiwan, he said.
Chen said the domestic agricultural ecological chain has not been contaminated, so people should feel safe consuming locally produced agricultural products.
Regarding some local governments ordering that flat rice noodles be temporarily removed from school lunch menus, and the question of whether this would affect rice prices, Chen said the ministry would monitor the situation, adding that he respects the local governments’ decisions as some flat rice noodle products include imported corn starch.
Separately, the ministry’s Agriculture and Food Agency on Friday said people should not be overconcerned about eating rice. The Chinese term for “bongkrek acid” (米酵菌酸) — literally meaning “fermented rice bacterial acid” — could easily cause a misunderstanding.
About 1.4 million tonnes of rice is produced in Taiwan each year, which is mostly milled into white rice or brown rice, then packaged for sale, but fermentation is not part of the manufacturing process, the agency said, adding that most of the rice is sold within six months of harvesting, so there is no risk of contamination.
It advised people to choose traceable packaged rice that has the Certified Agricultural Standard label, and also buy flat rice noodles or other rice products that have higher rice content, mixed with fewer other ingredients to reduce the risk of contamination.
