Investigation of paralytic shellfish poison pollution in commercially sold shellfish in Tianjin
摘要
Abstract
To understand the contamination status of paralytic shellfish poison(PSP)in commercially sold shell-fish in Tianjin,370 shellfish samples from 14 species were collected from large wholesale aquatic markets annually from April to August,from 2019 to 2023.The levels of PSP were detected with the enzyme-linked immunosorbent assay(ELISA)method.Among 370 samples,141 samples were positive for PSP,yielding a detection rate of 38.11％.The contents of PSP ranged from 4.05 to 79.24 μg/kg,with an average value of 17.83 μg/kg,all of which were below the maximum permissible limit of 800 μg/kg for safe consumption.The findings indicated that shellfish sold in Tianjin markets generally exhibited low PSP concentrations during the high-risk period from April to August each year.However,Scapharca subcrenata,Chlamys farreri,Mytilus galloprovincialis and Crassostrea gigas showed higher contamination probabilities and toxin levels.To mitigate PSP poisoning risks,early-warning monitoring of M.galloprovincialis and sustained monitoring of S.subcrenata,C.farreri,C.gigas and other sus-ceptible shellfish species are recommended.关键词
