Objective To understand the overall situation of biogenic amine content in various types of seafoods in Hainan Province, and conduct dietary risk assessment on the detected histamine. Methods A total of 387 batches of seafoods from supermarkets and farmers’ markets in 19 cities and counties of Hainan Province in 2022 were detected for 14 kinds of biogenic amines by ultra performance liquid chromatography-tandem mass spectrometry. Based on the detection results, the dietary exposure risk of the detected histamine was assessed by the hazard quotient (HQ). Results The average content of biogenic amine detected in 387 batches of seafoods were 0.101-55.248 mg/kg, and the maximum value were 2.248-10819.835 mg/kg. The higher levels of several biogenic amines were spermine, spermidine, histamine, putrescine, cadaverine and so on. And two samples detected histamine levels over 200 mg/kg. The dietary risk assessment showed that the estimated daily of histamine in different populations in Hainan Province were 0.00000-0.06690 mg·kg-1·bw-1·d-1, with HQ of 0.00000-0.00134 (HQ<1). Conclusion Biogenic amines are detected in all kinds of seafoods in Hainan Province to varying degrees, but the risk of histamine exposure is low, posing a small threat to human health.
