What’s the deal with sushi? (Special note)
Sushi often causes concern. Here’s what you should know:
Freshwater fish (for example, farmed salmon) are more likely to contain parasites than saltwater fish. Fish suitable for sushi is frozen to eliminate parasites.
Flash freezing at -20°C (-4°F) for 7 days eliminates parasites. Most reputable sushi suppliers follow this standard.
Avoid raw freshwater fish of unknown origin. Do not consume raw fish caught in local lakes or rivers unless it has been properly frozen.
Pregnant women, the elderly, and immunocompromised individuals should completely avoid raw fish.
What to do if you think you have parasites?
If you experience persistent digestive symptoms, unexplained fatigue, or weight loss, consult your doctor.
Diagnosis: Stool tests (often multiple samples) can detect parasites. Blood tests can detect antibodies. Imaging tests (ultrasound, CT scan, MRI) may be needed to assess organ involvement.
Treatment: Antiparasitic medications (albendazole, mebendazole, praziquantel, etc.) are effective for most infections. Treatment is specific to each parasite, so an accurate diagnosis is essential.
Do not self-diagnose or self-medicate. Some over-the-counter parasite removal products are ineffective and can be harmful.
