Swordfish, a popular game fish and a staple in many seafood restaurants, has been a topic of discussion when it comes to food safety. The debate revolves around whether swordfish should be cooked all the way through or if it’s safe to consume it rare. In this article, we’ll delve into the world of swordfish, exploring its unique characteristics, the risks associated with undercooking it, and the guidelines for safe consumption.
Understanding Swordfish
Swordfish, also known as Xiphias gladius, is a large, migratory fish that can be found in tropical and temperate waters around the world. It’s a popular choice among seafood enthusiasts due to its firm texture and mild flavor. Swordfish is also a good source of protein, omega-3 fatty acids, and various essential nutrients.
However, swordfish is also known to accumulate high levels of mercury, a toxic substance that can harm human health. Mercury is a potent neurotoxin that can damage the brain, nervous system, and kidneys. The FDA and EPA have established guidelines for safe mercury levels in fish, and swordfish is classified as a high-mercury fish.
The Risks of Undercooking Swordfish
Undercooking swordfish can pose several health risks, including:

Cooking Swordfish to Perfection
To minimize the risks associated with undercooking swordfish, it’s essential to cook it to the recommended internal temperature. The FDA recommends cooking swordfish to an internal temperature of at least 145°F (63°C). It’s also important to use a food thermometer to ensure the fish has reached a safe temperature.
Here are some general guidelines for cooking swordfish:
- Grilling: Preheat the grill to medium-high heat. Place the swordfish on the grill and cook for 4-6 minutes per side, or until it reaches an internal temperature of 145°F (63°C).
- Baking: Preheat the oven to 400°F (200°C). Place the swordfish on a baking sheet and bake for 8-12 minutes, or until it reaches an internal temperature of 145°F (63°C).
- Pan-searing: Heat a skillet over medium-high heat. Add a small amount of oil and place the swordfish in the skillet. Cook for 3-4 minutes per side, or until it reaches an internal temperature of 145°F (63°C).
Safe Handling and Storage
In addition to cooking swordfish to the recommended internal temperature, it’s also essential to handle and store it safely. Here are some tips:
- Handle swordfish safely: Always handle swordfish with clean hands and utensils. Avoid cross-contaminating other foods with swordfish juices.
- Store swordfish properly: Store swordfish in a sealed container and keep it refrigerated at a temperature of 40°F (4°C) or below.
- Consume swordfish promptly: Consume swordfish within a day or two of purchase. If you don’t plan to consume it immediately, consider freezing it.
Special Considerations
While cooking swordfish to the recommended internal temperature is essential, there are some special considerations to keep in mind:
- Pregnant women and young children: Pregnant women and young children are more susceptible to mercury toxicity and foodborne illness. It’s recommended that they avoid consuming swordfish altogether or limit their consumption to small amounts.
- People with weakened immune systems: People with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, should avoid consuming undercooked swordfish.
Conclusion
In conclusion, while swordfish can be a delicious and nutritious addition to a healthy diet, it’s essential to cook it to the recommended internal temperature to minimize the risks associated with undercooking. By following the guidelines outlined in this article, you can enjoy swordfish while protecting your health.

| 145°F (63°C) | Baking | 8-12 minutes |
| 145°F (63°C) | Pan-searing | 3-4 minutes per side |
By following these guidelines and taking the necessary precautions, you can enjoy swordfish while protecting your health. Remember, it’s always better to err on the side of caution when it comes to food safety.
What is the recommended internal temperature for cooked swordfish?
The recommended internal temperature for cooked swordfish is at least 145°F (63°C). This is the minimum temperature required to ensure that the fish is cooked through and safe to eat. It’s essential to use a food thermometer to check the internal temperature, especially when cooking swordfish to the recommended level of doneness.
It’s worth noting that swordfish can be cooked to different levels of doneness, depending on personal preference. However, it’s crucial to prioritize food safety and cook the fish to the recommended internal temperature to avoid the risk of foodborne illness. Cooking swordfish to the right temperature will also help to preserve its texture and flavor.
Can swordfish be eaten rare or medium-rare?
While some people may prefer to eat swordfish rare or medium-rare, it’s not recommended. Swordfish can contain parasites, such as Anisakis, which can cause food poisoning if the fish is not cooked to the recommended internal temperature. Eating rare or medium-rare swordfish increases the risk of foodborne illness, especially for vulnerable populations like the elderly, pregnant women, and people with weakened immune systems.
If you prefer your swordfish cooked to a lower temperature, it’s essential to ensure that the fish is sashimi-grade and has been previously frozen to a certain temperature to kill any parasites. However, even with sashimi-grade swordfish, there is still a risk of foodborne illness if the fish is not handled and stored properly.
How do I know if my swordfish is sashimi-grade?
Sashimi-grade swordfish is typically labeled as such by the fishmonger or supplier. However, it’s essential to ask questions and ensure that the fish has been previously frozen to a certain temperature to kill any parasites. You can also look for certifications like “sashimi-grade” or “sushi-grade” from reputable organizations.
It’s also important to note that even with sashimi-grade swordfish, there is still a risk of foodborne illness if the fish is not handled and stored properly. It’s crucial to handle the fish safely, store it at the right temperature, and consume it within a day or two of purchase.
