摘要： We used a risk-benefit model to evaluate the effects of different farming methods and consumption habits on dietary risk of Chinese mitten crab. In this study, we found that cadmium levels in the total edible parts and brown meat were 0.029-0.462 mg/kg and 0.017-1.694 mg/kg, respectively. Cadmium exposure experiment showed that brown meat was the main enrichment site of cadmium. Fatty acid test found that the EPA + DHA content in total edible parts fed with formulated feed and iced trash fish was 19.64 +/- 3.62 mg/g and 28.72 +/- 2.30 mg/g (p > 0.05), respectively, and that in brown meat was 27.66 +/- 5.16 mg/g and 40.15 +/- 3.50 mg/g (p > 0.05), respectively. According to the risk-benefit model analysis, the dietary risk of brown meat under the two breeding methods is relatively high, but the risk quotient is less than 1.
