For sushi and sashimi enthusiasts, raw fish is a popular and savory delicacy. Swordfish is a type of fish that some people enjoy consuming raw. While it can be a tasty treat, is it safe to eat raw swordfish? In this article, we will explore the nutritional value of swordfish, its health benefits and risks, and how to properly prepare and cook this fish.
What is Swordfish and its Nutritional Value?
Swordfish is a large fish that can be found in the Atlantic, Pacific, and Indian Oceans. It is known for its long, sword-like bill that extends from its face, hence its name. Swordfish is a rich source of protein, vitamin B12, selenium, and omega-3 fatty acids. This fish also contains varying amounts of other nutrients such as vitamins D and E, magnesium, and potassium.
In addition to its nutritional value, swordfish is also a popular fish for sport fishing due to its size and strength. However, it is important to note that swordfish can contain high levels of mercury, which can be harmful to human health if consumed in large quantities. It is recommended to limit consumption of swordfish to once a week or less, especially for pregnant women and young children.
Health Benefits of Eating Swordfish
Eating swordfish provides several potential health benefits. The omega-3 fatty acids found in this fish can help lower the risk of heart disease, improve brain function, and reduce inflammation in the body. Additionally, vitamin B12 is important for the proper functioning of the nervous system, while selenium can boost immune function and support healthy thyroid function.
Furthermore, swordfish is a great source of protein, which is essential for building and repairing tissues in the body. It also contains high levels of niacin, which can help regulate cholesterol levels and promote healthy skin. Additionally, swordfish is low in saturated fat and calories, making it a great option for those looking to maintain a healthy weight.
Risks Associated with Eating Raw Fish
Consuming raw fish carries potential health risks. Raw fish can contain harmful bacteria and parasites that can cause food poisoning, and this risk is magnified in certain types of fish, like swordfish. Eating raw swordfish can lead to mercury poisoning, a serious condition that can cause neurological damage. Other potential risks associated with eating raw fish include tapeworm infections, hepatitis A, and norovirus.
It is important to note that not all types of raw fish carry the same level of risk. For example, sushi-grade fish is typically frozen at very low temperatures to kill any potential parasites before it is served. Additionally, some cultures have been consuming raw fish for centuries and have developed methods to minimize the risk of illness.
If you do choose to eat raw fish, it is important to ensure that it is fresh and properly prepared. Look for reputable sushi restaurants that follow strict food safety guidelines. If you are preparing raw fish at home, make sure to purchase it from a trusted source and follow proper handling and storage procedures.
Cooking vs Eating Raw Swordfish: Pros and Cons
Cooking swordfish can be a safer option than consuming it raw. Cooking the fish adequately can kill any harmful bacteria and parasites that might be present in the fish, reducing the risk of food poisoning. However, cooking can also result in a loss of nutrients, like omega-3 fatty acids and vitamins. Moreover, overcooking can cause the fish to become dry and tough, which may detract from its taste and texture.
On the other hand, eating raw swordfish can provide a unique and flavorful experience. Raw swordfish has a delicate texture and a sweet, mild flavor that can be enjoyed with a variety of seasonings and sauces. Additionally, consuming raw fish can provide a higher concentration of certain nutrients, like vitamin B12 and zinc, which can be lost during the cooking process. However, it is important to note that consuming raw fish does come with some risks, including the potential for foodborne illness if the fish is not properly handled and prepared.
How to Properly Prepare Swordfish for Consumption
Proper preparation is critical when consuming swordfish, whether cooked or raw. If you plan to cook the fish, it is important to store it properly to avoid bacterial growth before cooking. If you plan to consume it raw, make sure to source high-quality fish from a reputable supplier, and never eat swordfish that has not been previously frozen. Freezing the fish at -4°F (-20°C) for at least 24 hours can kill any potential parasites in the fish.
When cooking swordfish, it is important to not overcook it as it can become tough and dry. The ideal internal temperature for swordfish is 145°F (63°C). You can also marinate the fish before cooking to add flavor and tenderize the meat. A simple marinade of olive oil, lemon juice, and herbs works well with swordfish.
It is also important to be aware of the potential health risks associated with consuming swordfish. Swordfish is a high-mercury fish, which means that it can be harmful to consume in large quantities, especially for pregnant women and young children. It is recommended to limit consumption to no more than once a week and to choose smaller swordfish, as they tend to have lower levels of mercury.
Tips for Buying High-Quality Swordfish
When buying swordfish, look for fish that has been sustainably sourced. This can help ensure that you are consuming fish that is free of contaminants and sustainably farmed. Additionally, opt for swordfish that is fresh and has a bright, shiny appearance, with a firm texture and a mild, sweet smell.
Another important factor to consider when buying swordfish is the color of the flesh. The flesh of the swordfish should be a light pink or beige color, with no dark spots or discoloration. Dark spots can indicate that the fish is not fresh or has been improperly stored. It is also important to check for any signs of freezer burn, such as dry or discolored patches on the flesh.
Different Ways to Cook Swordfish
Swordfish can be cooked in many different ways, each lending themselves to unique flavor profiles. Some popular cooking methods include grilling, broiling, baking, sautéing, and poaching. The key to cooking swordfish is to avoid overcooking it, as it can quickly become rubbery and dry. Aim for an internal temperature of 145°F (63°C) for juicy, flavorful swordfish.
One of the most popular ways to cook swordfish is by grilling it. This method imparts a smoky flavor to the fish and creates beautiful grill marks on the surface. Another way to cook swordfish is by baking it in the oven. This method is great for those who want a hands-off approach to cooking, as the fish can be seasoned and placed in the oven to cook while you prepare other dishes.
If you’re looking for a healthier way to cook swordfish, consider poaching it. Poaching involves cooking the fish in a flavorful liquid, such as broth or wine, which helps to keep it moist and tender. Sautéing is another option, which involves quickly cooking the fish in a hot pan with oil or butter. This method is great for those who want a crispy exterior and a tender interior.

This will infuse the fish with a delicious flavor and keep it moist and tender. Another great way to enjoy swordfish is to pair it with fresh vegetables, such as roasted asparagus or sautéed spinach. Not only does this add a nutritious element to your meal, but it also complements the rich flavor of the swordfish perfectly.
Alternatives to Raw Swordfish for Sushi and Sashimi Lovers
If you enjoy sushi and sashimi but want to avoid the potential risks associated with consuming raw swordfish, there are other fish options to consider.

Raw Swordfish: A Culinary Delight or a Health Hazard?
While some people may enjoy the taste of raw swordfish, it is important to consider the potential health risks associated with consuming this fish in its raw form. The risk of bacterial and parasitic contamination, as well as mercury poisoning, means that it is generally safer to consume swordfish that has been thoroughly cooked. If you are set on consuming raw swordfish, make sure to follow proper preparation and freezing techniques, and always source high-quality fish from a reliable supplier.
Raw swordfish is a popular dish in many cultures, particularly in Japan where it is known as “tataki.” However, it is important to note that the preparation and handling of raw fish requires a high level of skill and knowledge to ensure that it is safe for consumption. Improper handling can lead to foodborne illnesses such as salmonella and listeria.
Additionally, swordfish is a large predatory fish that can accumulate high levels of mercury in its flesh. Mercury is a toxic metal that can cause neurological damage and other health problems if consumed in large amounts. Pregnant women, young children, and those with compromised immune systems should avoid consuming raw swordfish altogether to reduce their risk of mercury poisoning.
Common Misconceptions About Eating Raw Seafood
There are many misconceptions about eating raw seafood, including that it is a delicacy and that all types of fish can be safely consumed raw. However, this is not the case. Some types of fish carry a higher risk of bacterial and parasitic contamination than others, and consuming raw fish can result in serious health consequences. It is important to educate yourself about the risks and benefits of consuming raw fish so that you can make informed decisions about your diet.
One common misconception is that sushi is always made with raw fish. While many types of sushi do feature raw fish, there are also many varieties that use cooked fish or no fish at all. Additionally, some sushi restaurants use frozen fish to reduce the risk of contamination, so it is important to ask about the preparation methods before ordering.
Another misconception is that consuming raw seafood is only dangerous for individuals with weakened immune systems. While it is true that certain populations, such as pregnant women and young children, are more susceptible to foodborne illness, anyone can become sick from consuming contaminated raw seafood. Symptoms can range from mild stomach discomfort to severe dehydration and hospitalization.
How to Store and Handle Raw Swordfish Safely
When handling raw swordfish, it is important to take proper precautions to avoid contamination. Store the fish at a temperature of 32°F (0°C) or below to prevent bacterial growth. If you plan to cook the fish within a few days, store it in the refrigerator. If you need to store the fish for a longer time, wrap it tightly in plastic wrap and freeze it. When handling the fish, always wash your hands thoroughly and use separate cutting boards and utensils for raw fish to avoid cross-contamination.
It is also important to note that swordfish can contain high levels of mercury, which can be harmful to human health. The FDA recommends that pregnant women, young children, and those with compromised immune systems avoid consuming swordfish altogether. For others, it is recommended to limit consumption to no more than once a week. When purchasing swordfish, look for sustainably sourced options to support responsible fishing practices and reduce the impact on the environment.
The Role of FDA Guidelines in Ensuring Safe Consumption of Raw Fish
The U.S. Food and Drug Administration (FDA) has established guidelines for the safe consumption of raw fish, including specific requirements for storing, handling, and preparing fish for consumption. These guidelines can help reduce the risk of foodborne illness and ensure that consumers can safely enjoy the benefits of raw fish. It is important to follow these guidelines when preparing and consuming raw fish to prevent illness.
Conclusion: Should You Eat Raw Swordfish?
While consuming raw swordfish can be a tasty treat for some, it carries potential health risks that should not be ignored. Cooking swordfish adequately can reduce the risk of foodborne illness and ensure that you receive the full nutritional benefits of this fish. If you do want to consume raw swordfish, it is important to source high-quality fish from reputable suppliers and follow proper preparation and freezing techniques. Whatever your preference, it is critical to make informed decisions about what you eat to keep your body healthy and safe.
