I'm not a fish eating person but I live in a fishing (and farming) region. I've heard people from here who have gone away on vacation say often the fish they are served is wrong. Usually it's a cheaper type substituted for more expensive species of fish.
From the article:
"Despite their name, herring worms can be found in a variety of marine fish and squid species. When people eat live herring worms, the parasite can invade the intestinal wall and cause symptoms that mimic those of food poisoning, such as nausea, vomiting and diarrhea. In most cases, the worm dies after a few days and the symptoms disappear."
You will still eat the worms, not that it is necessarily a bad thing. When I go fish in the south of Norway I see these worms in maybe 1 out of 10 fish I catch. I personally don't eat them but I don't think it's unhealthy as long as they are dead.
Considering health and seafood, I'd be much more worried about is eating Norwegian farmed salmon, that stuff is poison [1]. The amount of toxins has not go down since this article was warning Norwegians.
I never touch it myself and the wild fish you catch close to the mares are monsters compared to the fish that does not consume leftovers from feeding the salmon.
At least for the US, they requires some type of process but it is messier than perhaps it should be. For one the responsibility for freezing the fish can be shifted between the restaurant serving and the vendor, and might not be effective. This is because time tables for acceptable methods of freezing fish vary in length depending on the temperature they are stored at. Some of the higher temperatures takes a couple weeks, and for example a restaurant might be buying fresh fish and not storing them in a freezer long enough.
No. Fish for sushi is recommended to be flash frozen or frozen for X number of days to kill the parasites. FDA recommendations for freezing fish to kill parasites.
"Freezing and storing at an ambient temperature of -4°F (-20°C) or below for 7 days (total time), or freezing at an ambient temperature of -31°F (-35°C) or below until solid and storing at an ambient temperature of -31°F (-35°C) or below for 15 hours, or freezing at an ambient temperature of -31°F (-35°C) or below until solid and storing at an ambient temperature of -4°F (-20°C) or below for 24 hours are sufficient to kill parasites. Note that these conditions may not be suitable for freezing particularly large fish (e.g., thicker than 6 inches). "
You could freeze fish in your freezer since most freezers can do -4°F or lower, but it will just take longer to kill the parasites.
People also catch fish, check for parasites visually and then prepare it sushi/sashimi style and eat it. Even here, you'll generally be okay but the odds of getting sick increases.
Also, the article is from eurekaalrt and the headline is clickbait nonsense.
Even if "sushi parasite" increased 283 fold, what's the increase in sushi consumption? It went from pretty much 0 40 years ago to being almost ubiquitous today.
Per the article, “increased 283-fold” means a specific variety of worm is now more common in the fish. It doesn’t mean parasites have become more common in people. It’s consistent with these results for sushi freezing to still kill the worms.
Not all fish is required to be frozen to kill the parasites actually. there are classes of fish that are considered not significantly dangerous to warrant that procedure. I looked up the fda guidelines on it a while ago.
Where was the testing? After living in Japan I stopped eating sushi in the US. It's always painful when someone asks me to recommend a "good sushi place" here, I'm not sure what to say.
personally I prefer US sushi places, local salmon in particular is an insanely buttery and delectable slice of raw fish, Ive never understood the japanese obsession with rice, it’s fine but salmon is better imo
This is a horse shit study turned into click bait. It's a meta analysis (aka they built linear regression models on top of reported numbers in papers over a 37 year time span) and they explicitly state that it mostly applies to cetaceans rather than human beings. There are other results in the paper that indicate the methodology was flawed: aka other closely related, or ecologically similar worm species didn't increase in the samples in the meta data.
There's a larger lesson to be learned here, but at the moment stating the obvious about mass media dipshits reporting on bad stats doesn't seem to be appreciated.
