Swordfish, with its meaty texture and distinctive flavor, is a culinary delight enjoyed around the world. But when preparing this oceanic predator, a crucial question arises: can you eat swordfish a little rare? The answer isn’t a simple yes or no. It involves understanding food safety, the characteristics of swordfish, and personal risk tolerance.
Understanding the Risks: Bacteria and Parasites
The primary concern when consuming any seafood, including swordfish, is the potential presence of bacteria and parasites. These microorganisms can cause foodborne illnesses, ranging from mild discomfort to severe health complications. Cooking fish to the proper internal temperature is the most effective way to eliminate these risks.
Common Bacteria in Seafood
Several types of bacteria can contaminate seafood. Some of the most common include:
- Salmonella: Known for causing gastrointestinal distress.
- Vibrio vulnificus: A bacterium that can cause severe illness, particularly in individuals with weakened immune systems.
- Listeria monocytogenes: A concern for pregnant women, newborns, and individuals with compromised immune systems.
Parasites in Swordfish
While less common than in some other types of fish, swordfish can harbor parasites. These parasites are usually killed by thorough cooking. Freezing fish at specific temperatures for a certain duration is another method to eliminate parasitic risks.
Swordfish Quality and Handling
The quality of the swordfish and how it’s handled from catch to plate significantly impact its safety. Fresh, properly stored swordfish is less likely to contain high levels of bacteria.
Sourcing Matters
Purchase swordfish from reputable sources, such as established fishmongers or trusted grocery stores. Ask about the fish’s origin and how long it’s been since it was caught. Look for swordfish that is firm, has a fresh sea-like smell, and doesn’t appear slimy or discolored.
Proper Storage
If you’re not cooking the swordfish immediately, store it properly in the refrigerator. Wrap it tightly in plastic wrap or place it in an airtight container to prevent cross-contamination. Ideally, cook the swordfish within one to two days of purchase.
The Case for Cooking Swordfish Through
The U.S. Food and Drug Administration (FDA) recommends cooking fish, including swordfish, to an internal temperature of 145°F (63°C). This temperature is generally considered sufficient to kill harmful bacteria and parasites.
Achieving the Right Temperature
Use a food thermometer to ensure the swordfish reaches the proper internal temperature. Insert the thermometer into the thickest part of the steak, avoiding bone.
Texture and Flavor Considerations
Cooking swordfish to 145°F will result in a firm, opaque texture. While some may find it slightly dry, this level of doneness guarantees food safety.
The “Little Rare” Argument: Texture vs. Risk
Some chefs and adventurous eaters prefer swordfish cooked to a slightly lower temperature, resulting in a more tender and moist texture. This is where the “little rare” concept comes into play.
What Does “Little Rare” Mean?
“Little rare” generally refers to swordfish cooked to an internal temperature slightly below 145°F, perhaps around 130-140°F (54-60°C). The center of the steak will still be translucent.
Why the Appeal?
Swordfish cooked to this level retains more moisture and has a more delicate, buttery texture. Some argue that it enhances the overall flavor profile.
Weighing the Risks and Benefits of Undercooking
Choosing to eat swordfish a little rare involves weighing the potential benefits of improved texture and flavor against the increased risk of foodborne illness.
Risk Factors to Consider
Several factors can influence your personal risk:
- Age and Health: Individuals with weakened immune systems, pregnant women, young children, and older adults are more susceptible to foodborne illnesses.
- Swordfish Quality: The fresher and better-handled the swordfish, the lower the risk.
- Preparation Methods: Searing the outside of the swordfish can help kill surface bacteria, but it won’t eliminate parasites in the center.
Minimizing the Risks
If you choose to eat swordfish a little rare, take steps to minimize your risk:
- Source High-Quality Fish: This is the most crucial step. Choose a reputable supplier.
- Use a Thermometer: Don’t guess. Accurately measure the internal temperature.
- Consider Searing: Sear the outside of the swordfish to kill surface bacteria.
- Understand the Risks: Be aware of the potential consequences of eating undercooked fish.
Mercury Levels in Swordfish
Another important consideration when consuming swordfish is its mercury content. Swordfish is a high-mercury fish, and excessive mercury consumption can be harmful, especially for pregnant women, nursing mothers, and young children.
FDA Recommendations
The FDA recommends that pregnant women and young children limit their consumption of swordfish to avoid excessive mercury exposure. It’s advisable to consult with a healthcare professional for personalized guidance.
Balancing Benefits and Risks
For individuals who are not in high-risk groups, occasional consumption of swordfish is generally considered safe. However, it’s essential to be mindful of portion sizes and frequency of consumption.
Alternative Cooking Methods and Considerations
Beyond traditional grilling or pan-searing, other cooking methods can influence the safety and flavor of swordfish.
Sous Vide
Sous vide cooking involves cooking food in a water bath at a precise temperature. This method can help achieve a consistent level of doneness throughout the swordfish steak. However, it’s crucial to maintain the water bath at a safe temperature for a sufficient duration to kill bacteria.
Marinating
Marinating swordfish can enhance its flavor and tenderness. Some marinades may also have antibacterial properties. However, marinating alone is not a substitute for cooking to a safe internal temperature.
Making an Informed Decision
Ultimately, the decision of whether to eat swordfish a little rare is a personal one. It involves carefully weighing the risks and benefits, considering your individual health status, and making an informed choice.
The Importance of Transparency
Restaurants that serve swordfish a little rare should be transparent about the risks involved. Customers should be informed and given the option to request that their fish be cooked to a higher internal temperature.
A Note of Caution
If you have any doubts or concerns about the safety of eating undercooked swordfish, it’s always best to err on the side of caution and cook it to the FDA-recommended internal temperature of 145°F (63°C).
Conclusion: Enjoy Swordfish Responsibly
Swordfish can be a delicious and nutritious part of a balanced diet. By understanding the risks associated with consuming it a little rare, and taking appropriate precautions, you can enjoy this culinary treasure responsibly. Remember to source high-quality fish, use a food thermometer, and be mindful of your individual risk factors. If you’re unsure, cooking swordfish through to 145°F (63°C) is always the safest option.

Individuals particularly vulnerable to mercury’s effects, such as pregnant women and young children, should consult their doctor for personalized recommendations.
Does cooking swordfish to a higher temperature affect its taste and texture?
Yes, cooking swordfish to a higher temperature than some chefs recommend can indeed affect its taste and texture. Overcooking swordfish can result in a dry, tough, and less flavorful piece of fish. Swordfish is naturally a lean fish, meaning it has relatively low fat content. When overcooked, the moisture within the fish evaporates, leaving it with an undesirable texture.
However, finding the right balance between safety and quality is crucial. While some argue that cooking to the FDA’s recommended 145°F (63°C) may slightly compromise the texture, it ensures the elimination of harmful bacteria and parasites. Techniques like marinating, searing quickly over high heat, and using moist cooking methods can help mitigate the drying effect of higher cooking temperatures and retain more moisture and flavor in the swordfish.
Are there alternative cooking methods that are safer for eating swordfish slightly less cooked?
While no cooking method completely eliminates the risks associated with undercooked swordfish, certain techniques can potentially reduce them. Quick searing over high heat, followed by a short period of rest, can achieve a browned exterior while leaving the center slightly less cooked. However, this method still relies on the internal temperature reaching a safe level, at least closer to the recommended 145°F (63°C) near the surface.
Ultimately, the safest approach remains cooking the swordfish to the FDA’s recommended internal temperature. Techniques like sous vide, which involves cooking food in a water bath at a precise temperature, can offer more control over the cooking process and potentially allow for a more evenly cooked piece of fish with a slightly less cooked center, but it still needs to reach at least 145°F (63°C) in the middle to be deemed safe from harmful bacteria. However, it is crucial to verify the internal temperature throughout the fish before consumption. When in doubt, err on the side of caution and ensure thorough cooking.
What are the mercury level concerns with eating swordfish, and how do they relate to cooking it rare?
Swordfish is known to have relatively high mercury levels compared to other types of fish. Mercury is a neurotoxin that can accumulate in the body over time, potentially leading to adverse health effects, especially in pregnant women, young children, and individuals with certain medical conditions. While cooking does not reduce the mercury content in swordfish, it’s still relevant because it influences how frequently and how much swordfish one should consume.
The recommendation to cook swordfish thoroughly is primarily about eliminating the risk of foodborne illness, not reducing mercury exposure. However, the higher the risk you are willing to take regarding eating it rare, the more important it becomes to limit swordfish consumption due to the mercury levels. If someone chooses to eat swordfish slightly rare, despite the increased risk of foodborne illness, it becomes even more critical to adhere to guidelines regarding the frequency of consumption to minimize mercury exposure. Consulting a healthcare professional or referring to the FDA’s guidelines on fish consumption is recommended to make informed decisions about including swordfish in one’s diet.
