The presence of semicarbazide in crustaceans collected from natural habitats in Thailand

Semicarbazide (SEM) has been used as a marker residue of the banned veterinary drug nitrofurazone (NFZ). Although evidence indicates that SEM can be found in some natural crustaceans that have never been exposed to NFZ, such information is limited to a few species. The present study aimed to investi...

Description
Summary:Semicarbazide (SEM) has been used as a marker residue of the banned veterinary drug nitrofurazone (NFZ). Although evidence indicates that SEM can be found in some natural crustaceans that have never been exposed to NFZ, such information is limited to a few species. The present study aimed to investigate the natural occurrence of SEM in wild crustaceans in Thailand. A total of 14 species, all economically important food animals, were captured from different regions of Thailand. Tissue-bound SEM and its parent drug NFZ were determined by the UPLC-MS/MS and LC-MS methods, respectively. The results showed that while NFZ was not detected in any samples, the tissue-bound SEM could be found in every natural crustacean species investigated. However, the prevalence and concentration varied greatly. The occurrence of SEM in the freshwater palaemonid Macrobrachium prawns is generally much higher than in the marine penaeid shrimps/prawns. SEM was found in 33% and 80% of the giant river prawn (Macrobrachium rosenbergii) muscles (
