Authorities in northern **Lao Cai Province, Vietnam have indicted a bean sprout producer for allegedly manufacturing and distributing large quantities of bean sprouts using a banned chemical growth regulator.
According to the Lao Cai Department of Public Security, Chu Thi Hoa (36) has been charged with violating food safety regulations after investigators discovered the use of 6-Benzylaminopurine (6-BAP) during bean sprout production.
The case emerged after police received a tip-off on 29 March about the suspected use of prohibited chemicals in bean sprout production. Authorities raided the facility and seized more than four metric tons of bean sprouts that were being prepared for distribution.
Samples were sent to the Criminal Science Institute under the Ministry of Public Security, where laboratory testing confirmed the presence of 6-Benzylaminopurine, a plant growth regulator banned in food processing.
During questioning, Chu Thi Hoa admitted to using the chemical to accelerate sprout growth and improve visual appearance, making the sprouts look larger and more marketable.
Investigators reported that the facility produced 700 kg to 1 metric ton of bean sprouts per day, supplying wholesale markets in several northern regions, including Hanoi and Phu Tho Province.
Authorities estimate that approximately 510 metric tons of chemically treated bean sprouts were produced and sold from early 2024 until the raid.
According to regulations issued by the Vietnam Ministry of Health, 6-BAP is prohibited in food processing due to potential health risks. Prolonged exposure may cause damage to the liver, kidneys, and lungs, and in severe cases may be fatal.
Officials are continuing to collect evidence and expand the investigation to determine whether additional individuals or distributors were involved in the production and distribution of the contaminated bean sprouts.
Consumers in affected regions are advised to purchase bean sprouts from trusted sources and remain alert for updates from food safety authorities regarding the case.
