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, a total of 149 samples of 6-BAP were detected by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) in 1494 bean sprouts samples, which were collected from the year 2016 to 2020 in Shandong Province of China, and all 10.0 % samples contained 6-BAP residue above the maximum residue limit (MRL), and the average residue was 0.007 mg·kg^-1. Hazard quotient (HQ) of 6-BAP was 0.0 % for the general population, and 0.2 % for the consumer population. 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 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.
