I wonder how farmed mussels are farmed. If they are farmed in artificial pools, for them to have B12 in them they would still need to be supplemented with the relevant forms of cobalt. So either they wouldn't have the B12 because there'd be no supplementation, or they would have to be supplemented, which might actually mean the same sorts of problems we'd get from supplementation anywhere.
