Objective To investigate the contamination and distribution of cadmium (Cd) in crabs sold in Wenzhou, and instruct consumers to eat healthily. Methods Three crab species were collected from 51 markets in 6 counties and districts of Wenzhou. The content of Cd was determined by inductively coupled plasma mass spectrometry based on GB 5009.268-2016. Results The detection rate of Cd was 100% in 235 samples. The Cd pollution in Portunus crab increase during 2013, 2015 to 2017. The Cd content of muscle and hepatopancreas in Portunus crab and Scylla serrata was higher than that in Eriocheir sinensis Milne-Edwards (P0.05). The distribution of Cd in Portunus crab was hepatopancreas and gonad> pectoral muscle > leg muscle, there was no significant difference of cadmium content in different parts between female and male crabs (P>0.05). Conclusion Cd was mainly concentrated in hepatopancreas, which was irrelevant to crab species, sex and individual difference. Cd content of Portunus crab and Scylla serrata exceeded the standard seriously, especially in hepatopancreas. People should pay more attention to the Cd pollution of crabs, and reduce the intake of hepatopancreas if necessary. |
