Ever felt the need to go to the bathroom after eating sushi? It’s awful! Sushi is safe to eat. You might be wondering, “But why does sushi cause diarrhea?”

Do you think it is wise to forgo sushi altogether? Continue reading to find out how this delicious dish can sometimes become frustrating.

Are raw ingredients in sushi causing diarrhea?

You may be familiar with sushi if you like it. Enjoying delicious rolls is a good thing. There are some risks associated with eating raw foods. This doesn’t just apply to raw fish.

It is very unpleasant to contract a foodborne illness from eating raw fish. This condition can lead to severe vomiting and diarrhea.

These are the most common types of food poisoning. These are caused by eating undercooked or raw seafood.


Anisakiasis is a form of gastrointestinal illness. This is a type of gastrointestinal disease. This type of food poisoning can be attributed to the parasites Anisakis or Pseudoterranova, decipiens

Anisakis develops into an adult stage in marine mammals such as whales and dolphins. Its larvae parasitize mackerel and Todarodes fishes.

The latter, on the other hand is a bacterium which lives in the stomachs gray seals and large seals. This parasite can live in a variety of host animals. Other sea animals are also possible hosts. These include large invertebrates and crustaceans as well as fish species.

Both parasite larvae are found in saltwater fish muscles. A mild tingling sensation can be felt after eating raw fish. This is the worm crawling in your throat or mouth. It’s so horrible!

The parasite can be manually extracted by sushi masters. To avoid infection, they can also cough it up.

What happens in a matter of minutes or hours after eating contaminated raw fish. The parasites enter the esophagus. They then travel down the stomach wall or intestinal wall.

These bizarre movements can cause nausea, vomiting, or abdominal pain. If you are lucky, the worm will be released from your body via your vomiting.

This is the tricky part. It is possible to misinterpret the symptoms as peritonitis, stomach ulcer or appendicitis. These symptoms are thought to be caused by small intestinal blockages.

It is interesting to note that neither Anisakis nor Pseudoterranova can survive in your stomach. Their lives will end there, as it turns out.

But don’t worry, this episode isn’t over. You can manage the symptoms until your new friends die naturally. What can you do to stop this? To speed things up, you can use an anti-parasite medication such as albendazole.


Another parasite can cause problems when eating raw sushi. This is Diphyllobothrium latum. This strain is found in fish muscle tissue.

After being swallowed, the parasite will travel to the small intestines. The parasite can then return to its original life cycle, just as it did in the fish from which it was taken.

You will be surprised at what happens when it lands happily in your intestines. It will start its transformation from larva to fully-fledged adultworm. It can grow up to 10 meters in length!

Unfortunately, D. latum infection symptoms are very rare. You might be one of those lucky people who get the symptoms. It is possible to experience mild diarrhea or abdominal pain.

A parasite in your stomach is indicated by the tail sticking out of your rectum. It is possible that you are vitamin B12 and/or anemic at this time.

Here’s some good news. One dose of the anti parasite medication praziquantel is enough to take care of all your needs.


Vibrio parahaemolyticus is also linked to eating raw or undercooked seafood. This is especially true for oysters.

Infection can be indicated by vomiting, diarrhea, cramps in the abdomen, and nausea. Sometimes, symptoms include nausea, fever and headaches. People with compromised immune systems are more vulnerable.

Vibrio vulnificus, another Vibrio species, is also available. It was discovered in oysters, crabs, and clams.

Healthy people can be affected by this microorganism, which can cause vomiting, nausea, or watery diarrhea. The symptoms may include fever and abdominal cramps.

It can also enter blood circulation. It can also cause a fatal, whole-body infection. People with weaker immune systems or liver disease are at greater risk.

Vibrio species can also cause wound infections if open sores are exposed to infected water. Two examples are scrapes from opening oysters and working on sailboats.

People with a weak immune system are more likely to be infected.

Here’s more! Vibrio, a Gram-negative parasite, is much less annoying than D. latum. This parasite lives in saltwater, and is usually free-swimming.

Vibrio uses a single polar flagellum to move about the water. It attaches to plankton, fish, and shellfish.

Vibrio-infected seafood can be consumed for up to 24 hours before you start experiencing symptoms. They include nausea, vomiting, and watery diarrhea. It will typically resolve on its own after three days.

  • parahaemolyticus is only possible in the immunocompromised. For healthy individuals, you can drink lots of water to replenish the fluids that have been lost. This parasitic infection is not curable by antibiotics.

Is it possible to get diarrhea from sushi made with cooked ingredients?

Bacillus cereus is another foodborne illness linked to sushi. Consuming contaminated rice is another reason. The disease has also been linked to contaminated rice, meats, and vegetables.

Two types of Bacillus cereus infection are available: vomiting and diarrheal. The vomiting type is caused by contaminated rice products. One example is fried rice left at room temperature for too long.

You should only eat cooked sushi at the correct internal temperature. This will reduce the risk of foodborne illness.

Most people are not at risk if they eat raw fish. Others may be at greater risk.

This is the best way to reduce your chance of food poisoning. Use excellent food safety precautions. Make sure your sushi is properly prepared

Cook the fish fins until they reach 145°F. The flesh should become transparent and be easy to separate with a fork.

Wait for the oysters, mussels and clams to open before you prepare them. Cook the shellfish until they are ready for use in clams, oysters and mussels.

Hot sauce can not destroy bacteria. Alcohol can be used to clean certain goods. However, alcohol cannot kill Vibrio or other foodborne bacteria.

Another safety tip: You can eat sushi with raw fish if you have to. Because any parasites that may be present in the seafood will be destroyed by freezing. Unfortunately, freezing does not eliminate all dangerous bacteria.

How fast can diarrhea develop after eating bad sushi?

Initial symptoms include cramps in the stomach, nausea, vomiting, diarrhea, and diarrhoea. These symptoms can develop as soon as one hour after eating infected sushi. This can last up to 10 days. It all depends upon the source of infection.

Between the cooked and raw phases, wash your hands and wash your plates and utensils. Most people who get food poisoning do not need to be admitted to the hospital. However, you will not want to go to the bathroom.

More severe diseases than diarrhea can be caused by eating raw or undercooked seafood. People more vulnerable to foodborne illness can be at risk of developing life-threatening illnesses.

People with weak immune systems and pregnant women are more at risk. At greatest risk are children under five years old and those 65 and over. These high-risk individuals should not consume shellfish or raw fish.

If you are in this category, cook shellfish and fish thoroughly. If you are unsure if your situation is serious, consult your doctor or registered dietitian.
