From the Mass Fisheries website:
Infections in humans are generally limited to the extremities such as fingertips and feet, but may involve the joints, bones and lymphnodes. Individuals with cuts or scrapes are at higher risk forinfection. The most frequent symptom is the formation of apersistent bump or nodule under the skin. Additional symptoms mayinclude the formation of ulcers, swelling of lymph nodes and jointpain.
Anglers have inquired if striped bass that have been ?tainted? with Mycobacteriosis are still edible. The answer is yes! A recent check of published medical studies by Maryland Department of Health on this kind of infection in human beings shows that eating properly prepared and cooked rockfish has not been associated with human mycobacterialillness. They recommend that people not consume any raw striped bass or any fish that appears diseased. In preparing striped bass for consumption, common sense should prevail.Fish withopen, reddened lesions on the body or with signs of hemorrhage or darkened patches in the fillets should be discarded. Fish that appear to be healthy and are properly cooked are safe to eat. While handling an infected striped bass, especially if the skin is cut or scraped, can lead to skin infections, simple hygiene precautions can prevent this.
