Mahi-mahi, a vibrant and flavorful fish, is a popular choice among seafood enthusiasts. However, rumors about parasites and worms in mahi-mahi have raised concerns among consumers. In this article, we will delve into the world of mahi-mahi and explore the truth behind the presence of worms in these fish.
Understanding Mahi-Mahi and Their Habitat
Before we dive into the topic of worms in mahi-mahi, it’s essential to understand the fish itself and its habitat. Mahi-mahi (Coryphaena hippurus) is a tropical fish species found in warm, temperate, and subtropical waters around the world. They are known for their striking colors, impressive size, and rich flavor.
Mahi-mahi are pelagic fish, which means they spend most of their time in the open ocean, often near the surface. They are carnivores and feed on a variety of prey, including small fish, crustaceans, and squid. Their diet and habitat make them susceptible to parasites and worms, which we will discuss later.
The Presence of Worms in Mahi-Mahi
Now, let’s address the main question: do mahi-mahi have worms? The answer is yes, but it’s not as simple as a straightforward “yes” or “no.” Mahi-mahi, like many other fish species, can harbor parasites and worms. However, the type and prevalence of these parasites vary depending on several factors, such as the fish’s diet, habitat, and location.
One of the most common parasites found in mahi-mahi is the Anisakis worm, also known as the herring worm. This parasite is a type of nematode that can infect a wide range of fish species, including mahi-mahi. Anisakis worms are typically found in the fish’s flesh, particularly in the muscles and organs.
Another parasite that can infect mahi-mahi is the Cestode, a type of tapeworm. Cestodes are more commonly found in fish that feed on infected prey, such as small fish and crustaceans. These parasites can attach themselves to the fish’s intestines and feed on nutrients.

By being informed and taking the necessary precautions, you can enjoy mahi-mahi while minimizing the risk of consuming worms and parasites.
Q: What is the concern about Mahi-Mahi having worms?
The concern about Mahi-Mahi having worms stems from the fact that these fish can be parasitized by various types of worms, including nematodes, cestodes, and trematodes. Some of these parasites can be harmful to humans if ingested, causing foodborne illnesses. The most common parasite associated with Mahi-Mahi is the Anisakis worm, which can cause anisakiasis in humans.
Anisakiasis is a gastrointestinal infection that can cause symptoms such as abdominal pain, nausea, vomiting, and diarrhea. In severe cases, it can lead to intestinal blockage or perforation. As a result, it is essential to handle and cook Mahi-Mahi properly to minimize the risk of parasite transmission.
Q: How common is it for Mahi-Mahi to have worms?
Studies have shown that a significant percentage of Mahi-Mahi can be infected with parasites, including worms. According to the FDA, up to 75% of Mahi-Mahi caught in certain regions can be infected with Anisakis worms. However, it’s worth noting that the prevalence of parasites can vary depending on factors such as the fish’s diet, habitat, and geographic location.
Despite the high prevalence of parasites in Mahi-Mahi, the risk of infection can be significantly reduced by proper handling, storage, and cooking of the fish. In fact, the FDA recommends that all fish, including Mahi-Mahi, be frozen to a certain temperature to kill any parasites that may be present.
Q: How can I minimize the risk of getting worms from Mahi-Mahi?
To minimize the risk of getting worms from Mahi-Mahi, it’s essential to handle and cook the fish properly. This includes storing the fish at a temperature below 40°F (4°C) to slow down parasite growth, and cooking the fish to an internal temperature of at least 145°F (63°C) to kill any parasites that may be present.
In addition to proper handling and cooking, it’s also recommended to freeze the fish to a temperature of -4°F (-20°C) for a certain period to kill any parasites. This is especially important for raw or undercooked fish, as these can pose a higher risk of parasite transmission.
Q: Can I see the worms in Mahi-Mahi?
It’s unlikely to see worms in Mahi-Mahi with the naked eye, as they are typically small and embedded in the fish’s flesh. Anisakis worms, for example, are usually around 1-2 cm in length and can be difficult to spot. However, if you cut open the fish and examine the flesh closely, you may be able to see the worms or their larvae.
It’s worth noting that even if you can’t see the worms, they can still be present in the fish. This is why proper handling and cooking are essential to minimize the risk of parasite transmission.
