Occurrence and levels of nitrofuran metabolites in sea cucumber from Dalian, China.

???displayArticle.abstract???
The occurrence and levels of nitrofuran metabolites (NFMs) in sea cucumber (SC) from Dalian, China, are reported. Four metabolites including 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), 3-amino-2-oxazolidinone (AOZ), semicarbazide (SEM) and 1-aminohydantoin (AHD) in different SC products (fresh, instant and dry salted SCs) were measured. The frequency of occurrence for NFMs in all SC samples was 42.7%. The total NFM concentrations ranged from non-detectable to 64.6 ng g-1, with a mean of 3.59 ng g-1. AOZ and SEM were the dominant congeners, accounting for 40.1% and 59.1% of the total NFMs, respectively. The concentrations and patterns varied among different regions. Higher levels of NFMs were found in the fresh SC products, and the order for the average concentration of ∑4NFM was fresh > dry salted > instant.
