It has already been known for a long time fish, and in particular tuna, carry a lot of worms and parasites, which is why freezing rules are in place in pretty much every country. For example here are EU regulations regarding freezing Tuna https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=PI_...

Why is the headline trying to make it sound like it's new or a big deal? That's a terrible sensationalist website btw...

Any angler will know that, in some lakes, it seems like every fish is full of worms. I've always dealt with that by frying the crap out of them -- no medium-rare bass for me, sorry. Alternatively, I'm sure they're fine after a few weeks in the freezer. Rivers seem to be better, with worm presence (or at least, obvious worm presence) being less common. Additionally, I've never seen worms in bottom-feeding fish like catfish and carp.

Land based fish farms might be the future for seafood. Actually rooting for Nordic Halibut and Salmon Evolution.

The culprits, in this particular case, are the fishermen.

First, bonito is not tuna. Second, the reason there is a season for bonito is because of the parasites.

Move over mahi-mahi, here comes maha tuna.
