Brown meat of crab

Brown crab meat often contains higher levels of cadmium than white meat.  

UK advice is available from the NHS Eat well website and states: "Although it is recommended that regular fish-eaters should avoid eating brown crab meat [i.e. the brown meat of crab] too often, there is no need to limit the amount of white crab meat that you eat. There are no maximum recommended amounts for other types of shellfish." 

In order to ensure that consumption advice is representative and proportionate, between 2012 and 2013 the FSA commissioned a survey of the levels of cadmium in brown crab meat on sale in the UK. You can read the report by clicking the link below:

The EU has produced an information note on cadmium levels in brown crab meat, which you can read via the link below:

The note recommends that member states issue advice relevant to their specific consumer habits.
