Sushi food poisoning remedy


Sushi, a popular dish worldwide, can sometimes be a source of food poisoning due to the raw fish and other ingredients it contains. Dr. Christos Zavos, a board-certified gastroenterologist and hepatologist from Thessaloniki, Greece, explains that the primary risk factors associated with sushi consumption relate to the presence of pathogens and improper handling.

Pathogens in Raw Fish

Raw fish, a staple ingredient in many sushi varieties, can harbor various pathogens, including:

  • Parasites: Such as Anisakis, which can cause anisakiasis, presenting with severe abdominal pain, nausea, and vomiting.
  • Bacteria: Including Salmonella, Listeria, and Vibrio parahaemolyticus, which are known to cause gastrointestinal symptoms such as diarrhea, vomiting, and fever.
  • Viruses: Hepatitis A and Norovirus are among the viral pathogens that can be present in raw or undercooked seafood.

Improper Handling and Storage

The risk of food poisoning from sushi can also increase due to factors related to its preparation and storage:

  • Cross-Contamination: The use of contaminated kitchen tools or surfaces can introduce pathogens to sushi.
  • Improper Storage: Sushi must be stored at appropriate temperatures to prevent bacterial growth. Fish for sushi, especially, should be frozen at -20°C (-4°F) for at least 7 days or at -35°C (-31°F) for at least 15 hours to kill parasites.
  • Use of Contaminated Water: Water used in preparing sushi rice and washing ingredients can also be a source of contamination if not clean.

Prevention and Caution

Dr. Zavos emphasizes the importance of consuming sushi from reputable sources that adhere to strict food safety guidelines, including proper fish handling, preparation, and storage practices. Individuals with compromised immune systems, pregnant women, the elderly, and young children may consider avoiding raw or undercooked fish due to a higher risk of severe foodborne illness.

In cases where individuals experience symptoms suggestive of food poisoning after consuming sushi, it is crucial to recognize the importance of appropriate management to alleviate symptoms and prevent further complications. Dr. Christos Zavos, a board-certified gastroenterologist and hepatologist based in Thessaloniki, Greece, offers expert advice on managing such situations.

Initial steps include staying hydrated, as vomiting and diarrhea can lead to dehydration. Drinking clear fluids in small sips can help maintain hydration levels. It’s also advisable to rest and avoid solid foods for a few hours until vomiting stops. Gradually reintroducing bland foods, such as rice, bananas, or toast, can help stabilize the digestive system.

Over-the-counter remedies may provide relief from symptoms such as nausea and diarrhea. However, use these medications judiciously and consider consulting with a healthcare professional to ensure they are appropriate for your specific situation.

If symptoms persist, worsen, or if there is a high fever, blood in stools, signs of dehydration, or if the affected individual is very young, elderly, or has underlying health conditions, seeking medical attention is imperative.
