A recent study published in the journal Ocean and Coastal Research indicates that 96 percent of a sample of skipjack tuna caught off the southern coast of Brazil were infected with parasitic worms. Researchers examined 53 tuna and found over 1,600 worms infesting various organs of the fish, with only the kidneys and hearts remaining free of parasites. The study highlights the importance of sanitary inspection and immediate evisceration to prevent the migration of larvae from the viscera to the muscle tissue, which is the part consumed by humans. Despite the high infection rates, some experts suggest that the presence of worms may indicate that the fish come from a healthy ecosystem. University of Washington parasitologist Chelsea Wood noted that the life cycle of the anisakid roundworm integrates many components of the food web, suggesting that their presence does not necessarily indicate poor fish quality.
