Summary: 6-Benzylaminopurine (6-BAP) is an important ingredient in production of “toxic bean sprouts”. In order to assess health risk from 6-BAP residue in bean sprouts on a large sample size and wide sample range among large survey population, 6-BAP was detected in 149 out of 1494 bean sprouts samples collected in 2016–2020 in Shandong Province of China. High performance liquid chromatography-tandem mass spectrometry was used for analysis. Those 10.0 % samples contained 6-BAP residue above the maximum residue limit (MRL) and the average level was 0.007 mg·kg^-1. Hazard quotient (HQ) of 6-BAP was 0.0 % for the general population and 0.2 % for consumers. The daily exposure of 6-BAP was accounted for 0.0 % of the the acceptable daily intake (ADI) and the estimated daily intake (EDI) of all subjects surveyed was below ADI. From the perspective of public health, the occurrence of 6-BAP residue in bean sprouts could not pose a serious health risk problem. Strict regulations on the management of 6-BAP residue in bean sprouts and human health risk assessment should be recommended.
