Rare type of skin infection from seafood from NY's Chinese markets
Unfortunately, it's not a rare infection in wild fish. I once caught a bluefish that horrified me when I filleted it...the entire upper body cavity was filled with granulomas...granular infected tissue that superficially looks like eggs. Before throwing it out, I took a photograph that I sent to the DEC. They got back to me very quickly to tell me that it was Mycobacterium (same genus that causes tuberculosis and leprosy in humans), and to wash my knife and cutting board very well. Increasing numbers of striped bass have been caught with Mycobacterium infections...it is very, very common in the Chesapeake Bay breeding stock.
