Risk of Parasites in Raw Salmon
1. Common Parasites Found in Raw Salmon
Raw salmon may contain microscopic parasites, which can cause serious infections if ingested. These parasites are often found in wild-caught fish and may not be visible to the naked eye.
| Parasite | Description | Health Risks |
|---|---|---|
| Anisakis (Roundworm) | A parasitic worm found in raw fish | Causes anisakiasis, leading to stomach pain, nausea, and vomiting |
| Diphyllobothrium (Fish Tapeworm) | Can grow up to 30 feet in the intestines | Leads to nutrient deficiencies, weight loss, and digestive issues |
| Nanophyetus salmincola | Found in Pacific salmon | May carry bacterial infections, causing fever and diarrhea |
💡 Did You Know? If you use wild salmon for raw consumption, it MUST be deep-frozen to kill parasites and bacteria.

2. Symptoms of Parasitic Infections
If you consume raw salmon infected with parasites, symptoms may appear within hours or days and include:
✔️ Persistent stomach pain
✔️ Nausea & vomiting
✔️ Diarrhea & bloating
✔️ Unexpected weight loss
✔️ Fatigue & weakness
Severe cases can lead to intestinal blockage or allergic reactions. Seek medical attention immediately if you experience persistent symptoms after eating raw fish.
Risk of Bacterial Infections in Raw Salmon
1. Common Bacteria in Raw Salmon
Unlike parasites, bacteria are not destroyed by freezing. If salmon is improperly handled or stored, harmful bacteria can multiply, causing food poisoning.
| Bacteria | Source | Symptoms |
|---|---|---|
| Salmonella | Found in contaminated seafood | Fever, diarrhea, abdominal cramps |
| Vibrio | Present in raw shellfish & seawater | Severe stomach pain, vomiting, dehydration |
| Listeria | Grows in improperly stored seafood | Flu-like symptoms, dangerous for pregnant women |
💡 At-Risk Groups: Pregnant women, young children, elderly individuals, and those with weakened immune systems should AVOID eating raw salmon due to health risks.

2. Symptoms of Bacterial Food Poisoning
✔️ Fever & chills
✔️ Severe diarrhea & dehydration
✔️ Vomiting & nausea
✔️ Abdominal cramps
Food poisoning can be life-threatening if left untreated. If symptoms persist for more than 48 hours, consult a doctor immediately.
How to Reduce the Risk of Illness from Raw Salmon
1. Buy Sushi-Grade or Previously Frozen Salmon
✔️ Purchase from reputable seafood suppliers that follow strict handling guidelines.
✔️ Look for sushi-grade labels, meaning the fish has been deep-frozen to kill parasites.
✔️ Check the expiration date and buy the freshest salmon possible.

2. Deep Freezing Kills Parasites
✔️ Freeze salmon at -4°F (-20°C) for at least 7 days before consuming raw.
✔️ Deep-freezing at -31°F (-35°C) for 15 hours kills parasites more effectively.
✔️ NEVER eat fresh-caught wild salmon raw without freezing it first.
💡 WARNING: Even if frozen, wild salmon is NOT recommended for pregnant women, children, or people with weak immune systems.

3. Proper Storage & Handling
✔️ Refrigerate raw salmon at 40°F (4°C) or below.
✔️ Consume within 1-2 days of purchasing.
✔️ Keep salmon in airtight packaging to avoid cross-contamination.
✔️ Thaw frozen salmon in the refrigerator, NOT at room temperature.

4. Cook Salmon for Maximum Safety
✔️ Cook salmon to an internal temperature of 145°F (63°C) to eliminate bacteria.
✔️ Searing or partially cooking the surface reduces contamination risks.
✔️ Ceviche & curing (gravlax) do NOT kill parasites—only freezing does.
💡 Safer Alternative: Try hot-smoked salmon, which is fully cooked and has a delicious, smoky flavor.
