All infections involving parasites are transmitted by eating raw or uncooked fish products. Control measures to reduce the public health problem related to the presence of parasites include:

• Avoidance of capture and consumption of nematode-infected fish by selecting specific fishing grounds, specific species or specific age groups.
• Sorting and removal of nematode-infected fish or removal of nematodes from fish.
• Application of techniques to kill nematodes in the fish flesh (Ex. Freezing)
