If attacked or bitten, attempt to identify the type of fish or animal, the time of the injury, and the nature of the attack. Bites or puncture wounds to the hand, wrist, foot, or joint are very dangerous and require immediate medical attention. Ocean bacteria are particularly dangerous. Infections often occur. Local wound infection may develop in as little as 24 hours.
All bite wounds require immediate copious cleansing with fresh tap water.
Gently scrub the wound with soap and water to remove foreign material. If a syringe is available, it should be used to provide high-pressure irrigation. Remove dead tissue with a sterile scissors or scalpel. After cleansing, apply a topical Bacitracin ointment 3 times per day. Wounded extremities should be immobilized and elevated.
