选取经检测氯霉素含量超标的中华绒螯蟹,利用水产品中氯霉素残留测定气相色谱法,对其性腺(蟹黄)、肌肉和肝脏等可食部分分别进行了测定,结果在污染的中华绒螯蟹的性腺(蟹黄)和肌肉中均未检出氯霉素,而在肝脏中检出大量氯霉素。所以在中华绒螯蟹氯霉素检测过程中,样品处理应特别注意肝脏的取舍,同时也提醒人们谨慎食用中华绒螯蟹的肝脏。
The Chinese mitten crab (E. sinensis) with over-detected chloramphenicol content was selected, and its edible parts such as gonad (crab), muscle and liver were determined by gas chromatography in chloramphenicol residues in aquatic products. There was no chloramphenicol in the gonads (crabs) and muscles of the mitten crab, whereas a large amount of chloramphenicol was detected in the liver. Therefore, during the detection of chloramphenicol in the mitten crab, the sample treatment should pay special attention to the choice of the liver, but also remind people to eat crab liver cautiously.
