You’ve probably seen it. Maybe it popped up in your TikTok feed or a frantic group chat. A video surfaced showing a parasitic worm—anisakis, most likely—wriggling around in a piece of raw fish from Fob Sushi Bar in Seattle. It’s the kind of thing that makes you want to swear off spicy tuna rolls forever. Honestly, seeing a live parasite in food you're about to put in your mouth is a visceral, stomach-turning experience.
But here is the thing about the fob sushi worm incident: it isn't actually a sign of a "dirty" restaurant. It’s a sign of how nature works.
Raw fish comes from the ocean. The ocean is full of life. Some of that life is microscopic, and some of it is slightly larger, like the nematodes we found ourselves staring at on our phone screens back in late 2024. When the video went viral, the internet did what it does best. It panicked. People started calling for permanent closures. They questioned every "cheap" sushi spot in the Pacific Northwest. Yet, if we look at the actual biology of seafood and the regulations governing the industry, the story gets a lot more nuanced than just "gross worm in fish."
The Viral Moment: Breaking Down the Fob Sushi Incident
The drama started when a customer at Fob Sushi Bar’s Belltown location filmed a translucent, thread-like worm moving inside their sashimi. It wasn't just a stagnant speck. It was active. Within hours, the clip had millions of views. The restaurant, facing a PR nightmare, ended up temporarily closing its Belltown and Capitol Hill locations to conduct internal investigations and address the public outcry.
Public health officials from Seattle & King County eventually stepped in. Interestingly enough, their subsequent inspection didn't find major systemic failures that would typically cause a parasitic outbreak. The restaurant was following standard protocols. So how did the fob sushi worm get through?
It basically comes down to a failure in "candling" or visual inspection. Every piece of sushi-grade fish goes through a process where chefs or suppliers hold the fillets up to a light source to spot parasites. Most of the time, they find them. They pluck them out with tweezers. You never see them. Sometimes, a worm is buried deep in the muscle fibers or is so small it bypasses the human eye.
Understanding Anisakis: The Biology of the Beast
The worm in question is almost certainly Anisakis simplex. These are common parasites found in salmon, herring, cod, and mackerel. They have a complex life cycle that involves marine mammals like seals or whales. The mammals poop out eggs, the eggs are eaten by crustaceans, the crustaceans are eaten by fish, and suddenly, you have a worm in your nigiri.

If you happen to ingest a live one, it leads to a condition called anisakiasis. It isn't fun. It feels like severe food poisoning—abdominal pain, nausea, vomiting. The worm tries to burrow into the lining of your stomach, realizes it’s not in a fish anymore, and eventually dies because humans are a "dead-end host." We aren't part of their natural life cycle.
Most people don't realize that the FDA actually has a "Parasite Destruction Guarantee." This is the "sushi-grade" standard. It requires that fish intended for raw consumption must be frozen at specific temperatures for a set amount of time. Usually, this means:
- $-4^{\circ}\text{F}$ ($-20^{\circ}\text{C}$) or colder for seven days.
- $-31^{\circ}\text{F}$ ($-35^{\circ}\text{C}$) or colder until solid and then stored at that temperature for 15 hours.
- $-31^{\circ}\text{F}$ ($-35^{\circ}\text{C}$) or colder until solid and stored at $-4^{\circ}\text{F}$ ($-20^{\circ}\text{C}$) for 24 hours.
If the fob sushi worm was still moving, it implies a breakdown somewhere in that freezing chain. Or, it could be a rare case of a "super worm," though that's more sci-fi than reality. More likely, the fish was "fresh" and never properly deep-frozen, or the freezer didn't hit the required metrics.
Is "Fresh" Sushi Actually Better?
We have this weird obsession with "fresh" fish. We think if a boat caught it this morning, it's safer. In the world of sushi, that is exactly backwards. "Fresh" fish is high-risk fish.
Truly safe sushi is almost always "frozen at sea." This flash-freezing process kills the larvae of parasites like Anisakis. When you eat at high-end Michelin-star sushi dens, you are often eating fish that has been frozen and then carefully thawed. It preserves the texture and, crucially, kills the worms.
The fob sushi worm incident happened because the barrier between the ocean's wild reality and the consumer's plate failed. When you eat wild-caught seafood, you are engaging with a wild ecosystem. It isn't a lab-grown product. According to a study by the University of Washington, the abundance of Anisakis worms has increased 283-fold since the 1970s. Think about that. There are literally hundreds of times more worms in the ocean now than when our parents were eating sushi.

Why? Because we’ve done a better job of protecting marine mammals. More whales and seals mean more hosts for the parasites. It's a weird paradox where environmental success makes our dinner slightly more dangerous.
How to Spot a Problem Before You Eat
You shouldn't have to be a marine biologist to enjoy dinner. But after the Seattle incident, people are rightfully paranoid. If you're sitting at a bar and you’re worried, look for these things.
First, check the translucency. Most parasites are white or clear. If you see a "vein" that seems to be coiled or thicker than the surrounding tissue, poke it with your chopstick. Parasites are surprisingly resilient. They don't just melt away.
Second, know your fish. Species like wild salmon and mackerel are notorious for carrying parasites. Farmed salmon is actually much safer in this specific regard. Because farmed salmon are fed pellets and kept in controlled environments, they rarely contract Anisakis. If you are truly terrified of the fob sushi worm scenario, sticking to farmed Atlantic salmon is your safest bet. It sounds counterintuitive to "foodies," but it's basic biology.
Third, look at the price point. This isn't to say cheap sushi is always bad, but the labor required to meticulously "candle" and inspect every ounce of fish is expensive. High-volume, low-cost establishments are moving fast. When you move fast, you miss things.
The Aftermath for Fob Sushi Bar
The restaurant eventually reopened, but the damage to a brand in the age of social media is hard to calculate. They released statements emphasizing their commitment to food safety and their partnership with reputable suppliers. But the internet has a long memory. If you search for "sushi in Seattle," those worm videos still linger in the algorithm.

It’s worth noting that the King County Health Department’s records show that most sushi restaurants in the area maintain high safety ratings. The fob sushi worm was a statistical outlier that happened to be caught on high-definition video. It’s a "black swan" event for the restaurant but a daily reality for the fishing industry.
Is it fair that one video can ruin a business? Maybe not. But it has forced a broader conversation about transparency in the seafood supply chain. We want to know where the fish comes from, how it was frozen, and who inspected it.
Real-World Advice for Sushi Lovers
If you're going out for sushi tonight, don't cancel your reservation. Just be smart.
Honestly, the risk of getting sick from a parasite is significantly lower than the risk of getting "normal" food poisoning from cross-contamination or poor refrigeration. Bacteria like Salmonella or Listeria are much more common and arguably more dangerous, yet they don't go viral because you can't see them wriggling.
What you can do right now:
- Ask the server: Don't be shy. Ask if their fish is "sushi-grade" and if it has been frozen according to FDA parasite destruction protocols. A good restaurant will know the answer immediately.
- Avoid "wild" if you're anxious: If the menu brags about "fresh, never frozen wild salmon," that's actually a red flag for parasites. You want it to have been frozen.
- Inspect your food: It takes two seconds. Just look at the fish before you dunk it in soy sauce.
- Trust your gut: if the fish feels mushy, smells overly "fishy" (fresh fish shouldn't smell like much of anything), or looks dull, just send it back.
The fob sushi worm was a gross-out moment that captured the public's imagination, but it's also a reminder that our food comes from a living, breathing, and sometimes parasitized world. Knowledge is the best way to handle the "ick" factor.
If you ever do find a worm in your food, don't just post it to TikTok. Alert the management immediately. They need to pull that entire batch of fish. Then, contact your local health department. They keep track of these incidents to see if a specific supplier is failing to meet the freezing standards.
Your next step is simple: keep eating sushi if you love it, but maybe pay a little more attention to the texture of that salmon. Most of the time, that "vein" is just a vein. But every once in a while, it's a guest from the deep sea. Stay informed, stay observant, and don't let a viral video rob you of a good meal—just make sure it’s a properly frozen one.
