People do eat raw tuna, but it is not risk-free: raw or undercooked fish is more likely than cooked fish to contain parasites or bacteria, and mishandled tuna can contain histamine that cooking will not destroy. Cooking seafood to an internal temperature of 145°F (63°C) is the safest practical choice for reducing foodborne illness risk. Raw tuna is not a sensible routine food for cats or dogs; consult a veterinarian about a pet’s diet.
If you are asking whether a cat or dog can eat raw tuna, human-food guidance is not a pet-feeding recommendation. The CDC does not recommend feeding raw pet food or treats to dogs and cats. Raw fish also raises nutritional concerns, including thiaminase, an enzyme that destroys thiamine. Ask your veterinarian before making decisions about a pet’s diet.
Fresh tuna can be raw—but “fresh” alone is not enough
Restaurants and fishmongers may serve tuna raw, but appearance or the word “fresh” does not establish that a particular portion is safe. FDA consumer guidance says raw or undercooked fish is more likely than cooked fish to contain parasites or bacteria. Buy seafood that has been kept refrigerated or properly iced, and ask the seller how it was handled. No label or freezing claim is a universal guarantee against pathogens or histamine.

Why freezing does not make raw tuna completely safe
Raw or undercooked fish can carry parasites as well as bacteria. Freezing can kill parasites that may be present in some fish, but FDA guidance cautions that freezing does not kill all harmful germs. Previously frozen tuna is therefore not equivalent to cooked tuna for overall safety. FDA recommends cooking seafood thoroughly as the safest practical option for reducing foodborne illness risk.
Some tuna species are exceptions to particular parasite-destruction freezing requirements in the FDA Food Code. That regulatory exception is not a consumer guarantee that every tuna portion is safe to eat raw, and it does not eliminate bacterial contamination or histamine risks.
Tuna has a special risk: histamine poisoning
Tuna is among the fish associated with scombrotoxin, or histamine, fish poisoning. Time-temperature abuse can allow histamine to form in susceptible fish. Once formed, the toxin is not destroyed by freezing or cooking. This is a separate hazard from parasites and bacteria: cooking cannot rescue tuna that was mishandled and developed histamine.
Do not rely on later cooking, freezing, or normal appearance to guarantee safety after temperature abuse. If you feel ill after eating tuna, seek medical advice; treat severe or concerning symptoms urgently.

Is canned tuna raw?
No. Commercial canned tuna is heat-processed, not raw. An unopened commercial can or retort pouch is normally ready to eat cold or warm. After opening, refrigerate leftovers promptly and follow the product’s storage instructions. Do not eat a can that is swollen, leaking, badly damaged, or spurts when opened.
Fresh raw tuna versus canned tuna
| Product | Preparation and safety distinction | Can you eat it cold? |
|---|---|---|
| Fresh tuna served raw | Uncooked fish with parasite, bacterial, and handling-related histamine concerns; freezing does not address every hazard | People may choose to, but it remains higher risk than cooked fish |
| Commercial canned or retort-pouch tuna | Heat-processed and ready to eat while unopened | Normally yes |
| Cooked tuna | FDA recommends cooking seafood to an internal temperature of 145°F (63°C) | Yes, once prepared and stored safely |
The safest alternative: cook tuna to 145°F
For the safest practical choice, cook tuna to an internal temperature of 145°F (63°C). Use an instant-read food thermometer to check the thickest part. A thermometer verifies temperature; it does not detect parasites or histamine and cannot neutralize histamine formed before cooking.
Cooking addresses foodborne illness risks associated with raw or undercooked seafood, but it does not reduce mercury. Mercury recommendations are a separate issue.
Who should avoid raw tuna?
FDA guidance advises pregnant people, children, older adults, and people with weakened immune systems to avoid raw or undercooked seafood because they are at increased risk from foodborne illness. These groups should choose thoroughly cooked seafood. FDA and EPA mercury advice should also be considered separately, especially during pregnancy and breastfeeding.

Raw-tuna safety and mercury are separate questions
Whether tuna is raw or cooked addresses food-safety concerns; mercury exposure is a separate issue that cooking does not resolve. FDA/EPA advice assigns different categories to tuna species:
| Tuna type | FDA/EPA category |
|---|---|
| Canned light tuna, including skipjack | Best Choice |
| Albacore or white tuna | Good Choice |
| Yellowfin tuna | Good Choice |
| Bigeye tuna | Choice to Avoid |
These are consumption-advice categories, not statements about raw preparation safety. Vary seafood choices and consult the full FDA/EPA advice for serving recommendations, particularly during pregnancy or breastfeeding.
What about feeding raw tuna to cats or dogs?
The CDC does not recommend feeding raw pet food or treats to dogs and cats because raw food can spread foodborne illness to pets and people who handle it or clean contaminated surfaces. Raw fish can also contain thiaminase, which destroys thiamine; cooking destroys that enzyme. These concerns support caution about feeding raw fish as a regular diet, not a diagnosis from a single accidental bite.
Raw pet diets also raise contamination and nutritional-balance concerns. Consult a veterinarian about a pet’s age, health, and complete diet before offering tuna or considering any raw-food diet. Keep raw seafood away from pet bowls and household food-preparation areas, wash hands and utensils after handling it, and clean contaminated surfaces. If a pet becomes ill after eating raw tuna, contact a veterinarian and explain what was eaten and when.

A quick decision checklist
If you are considering raw tuna for yourself, remember:
- Raw fish carries more parasite and bacterial risk than cooked fish.
- Freezing may address parasites in some fish but does not kill every harmful germ.
- Proper chilling matters because histamine can form after time-temperature abuse, and cooking or freezing will not destroy it.
- Use clean hands, utensils, and surfaces to prevent cross-contamination.
- If you are pregnant, a child, an older adult, or immunocompromised, avoid raw or undercooked seafood.
- When in doubt, cook seafood to 145°F (63°C).
FAQ
Is raw tuna safe to eat?
Raw tuna is not risk-free. Raw or undercooked fish is more likely than cooked fish to contain parasites or bacteria, and tuna can develop histamine after time-temperature abuse. Cooking to 145°F (63°C) is the safest practical choice for reducing foodborne illness risk.
Does freezing tuna make it safe to eat raw?
No. Freezing can kill parasites that may be present in some fish, but it does not kill all harmful germs. It also does not destroy histamine that has already formed.
Can pregnant people eat raw tuna?
FDA advises pregnant people to avoid raw or undercooked seafood because it is more likely to contain parasites or bacteria. Mercury advice is separate; consult FDA/EPA recommendations for tuna species and serving guidance.
