Mahi mahi, also known as dolphinfish or dorado, is a popular fish found in tropical and subtropical waters around the world. Its tender, mild flavor and firm texture make it an excellent choice for grilling, baking, or pan-searing. But can you safely eat mahi mahi when it’s cooked rare or even raw? Here’s a comprehensive look at the risks and benefits of eating undercooked mahi mahi.
Is it safe to eat raw mahi mahi?
Eating raw mahi mahi is generally not recommended. Like many other fish meant for cooking, raw mahi mahi may contain bacteria, parasites, and other contaminants that can cause foodborne illnesses. Here are some key risks of eating raw mahi mahi:
- Parasites – Mahi mahi are susceptible to parasitic infections from nematodes, trematodes, cestodes, and copepods. Eating raw, undercooked, or improperly frozen fish can transfer living parasites to humans.
- Bacteria – Raw seafood may contain pathogenic bacteria like Salmonella, Vibrio, Listeria, Staphylococcus aureus, and Escherichia coli. Proper cooking neutralizes these bacteria.
- Toxins – Mahi mahi from some waters may contain ciguatoxin or other natural marine toxins that can cause ciguatera fish poisoning. Cooking does not destroy these toxins.
- Allergies – People with fish allergies may react to consuming raw mahi mahi.
For these reasons, the FDA recommends cooking mahi mahi to an internal temperature of 145°F (63°C) to kill any potential parasites, bacteria, and viruses.
Is it safe to eat rare mahi mahi?
Eating mahi mahi cooked rare, medium-rare, or “just seared” also carries some risks. While cooking to these lower internal temperatures (110-125°F or 43-52°C) may kill some pathogens, it does not guarantee the fish is safe from all bacteria or parasites:
- Parasites may survive temperatures up to 145°F (63°C).
- Bacteria like Vibrio can continue to thrive at temperatures below 140°F (60°C).
- Toxins like ciguatoxin are not destroyed by heat.
For this reason, the FDA advises against eating mahi mahi raw or undercooked. Pregnant women, children, older adults, and those with weakened immune systems are considered at highest risk of foodborne illness from eating undercooked fish.
Benefits of eating rare or raw mahi mahi
While not recommended from a food safety standpoint, some people may choose to eat raw or rare mahi mahi because:
- It alters the texture and flavor compared to well-done fish.
- Rare cooking preserves moisture and makes the flesh flakier.
- Some culinary traditions and cultures prize the smooth, tender texture of raw fish.
- Raw fish dishes like ceviche “cook” the fish in acidic citrus juice.
- Some feel eating raw, fresh seafood provides beneficial nutrients.
If you choose to eat mahi mahi rare or raw despite the risks, there are a few precautions you can take:
- Buy sushi/sashimi-grade fish from a trusted source.
- Freeze the fish for 7 days at -4°F (-20°C) before eating raw (kills parasites).
- Avoid fish from waters known to have ciguatera toxins.
- Don’t serve raw fish to those with increased risk of illness.
Tips for cooking mahi mahi safely
To enjoy mahi mahi’s signature flavor and texture while minimizing the risks of foodborne illness, follow these food safety guidelines:
- Purchase fresh, refrigerated fish that is cold to the touch and doesn’t smell overly “fishy.”
- Check that the flesh is glossy, firm, and springs back when pressed.
- Keep raw fish very cold during storage and transport home.
- Wash hands, prep tools, and surfaces after handling raw fish.
- Marinate fish in the refrigerator, not on the counter.
- Use separate plates/utensils for raw and cooked fish.
- Cook fish to an internal temperature of at least 145°F (63°C).
- Refrigerate leftovers within 2 hours and use within 3-4 days.
How to tell when mahi mahi is cooked properly
Checking the internal temperature of the thickest part of the fish with a food thermometer is the best way to determine doneness. Look for a reading of at least 145°F (63°C).
If you don’t have a thermometer, use these visual and textural cues to check for proper doneness:
- The flesh turns opaque and flakes easily with a fork.
- The center is no longer translucent.
- The fish separates cleanly from the bone (for fillets).
Err on the side of overcooking to be safe. Cooked mahi mahi will have a firmer, drier texture compared to rare fish.
How restaurants prepare mahi mahi
Reputable restaurants understand the importance of seafood safety. Here are some standard practices restaurants may follow when serving mahi mahi:
- Using fresh, sushi/sashimi-grade fish from licensed suppliers.
- Storing fish properly to prevent temperature abuse.
- Adhering to minimum cooking temperatures and standards.
- Training staff on safe prep, handling, and cooking procedures.
- Keeping raw and cooked items separated.
- Cleaning and sanitizing food contact surfaces diligently.
- Discarding fish that is past its prime.
When dining out, check that the establishment looks clean, without major health code violations. Send any dish back that smells or looks questionable.
Common cooking methods for mahi mahi
Mahi mahi’s versatile texture stands up well to almost any cooking method. Some popular preparation styles include:
- Baking – Baked mahi mahi turns moist, flaky, and tender. Brush with oil or sauce and bake at 400°F for 15-20 minutes.
- Grilling – The intense heat of the grill lends great char flavor. Grill 4-6 minutes per side.
- Broiling – Similar results as grilling. Broil 4-5 inches from heat for 8-10 minutes.
- Pan-searing – Cook in a hot pan with oil for 3-4 minutes per side to caramelize the exterior.
- Blackening – Coat with a spicy blackening seasoning blend and sear in a cast iron skillet.
- Poaching – Gently simmering fish in stock or wine keeps it tender. Cook 4-6 minutes.
Regardless of technique, always verify the fish reaches the minimum safe internal temperature by the end of cooking.
