Fish is a popular and healthy source of protein that can be found in many different types of cuisine all around the world. However, not all fish are safe to eat, and some species can actually be poisonous to humans. In this guide, we’ll take a look at some of the fish you should avoid when it comes to human consumption.
1. Pufferfish
Pufferfish, also known as fugu, is one of the most infamous poisonous fish out there. It’s a delicacy in Japan, where chefs who serve it must have a special license due to the high risk of poisoning. The pufferfish has a toxin called tetrodotoxin, which is found in its skin, liver, and ovaries. If consumed in large amounts, it can lead to paralysis and even death.
2. Barracuda
Barracuda is a type of fish that is commonly found in warm, tropical waters. While it’s not poisonous itself, barracuda can carry a toxin called ciguatera, which is produced by a type of algae that it consumes. Ciguatera can cause gastrointestinal and neurological symptoms, such as vomiting and numbness, and can take days or even weeks to resolve.
3. Red Snapper
Red snapper is a popular fish that is commonly found in the Gulf of Mexico and the Caribbean. However, it’s important to be aware that some red snapper can carry a toxin called ciguatoxin, which is produced by a type of algae that it consumes. Like ciguatera, this toxin can cause gastrointestinal and neurological symptoms, and can take weeks or even months to resolve.
4. Escolar
Escolar, also known as oilfish, is a type of fish that is often mislabeled as white tuna or butterfish. While it’s not poisonous, escolar can cause gastrointestinal symptoms such as diarrhea and vomiting due to its high levels of wax esters. These can’t be digested by humans and can lead to digestive issues if consumed in large amounts.
5. Scombroid Fish
Scombroid fish, such as tuna, mackerel, and bonito, can cause a type of food poisoning called scombroid poisoning. This occurs when the fish is not stored at the proper temperature and begins to spoil. The bacteria in the fish produce histamine, which can lead to symptoms such as flushing, headaches, and palpitations.
Overall, while fish is a healthy and delicious source of protein, it’s important to be aware of the types of fish that can be poisonous to humans. By avoiding these fish and being aware of the risks associated with consuming certain types of fish, you can enjoy the benefits of this nutritious food without putting your health at risk. Always make sure to purchase fish from reputable sources and to store and cook it properly to reduce the risk of foodborne illness.
In conclusion, while fish is a great source of protein and other essential nutrients, it is important to be aware of which species are dangerous or poisonous to humans. Knowing which fish to avoid can help you stay safe and healthy. By following the tips and guidelines we have provided in this guide, you can ensure that you make informed decisions when it comes to choosing the right type of fish for your meals.
