If you have ever eaten fish before, there is a good chance you have heard of histamine. This chemical is responsible for the strong flavours and aromas that many fish possess. So, what is histamine, and how does it get into our food? Let’s discuss the role histamine plays in seafood, and why it is important to avoid eating fish with high levels of this toxin.
According to fresh tuna suppliers and swordfish suppliers, histamine is a naturally-occurring chemical that is found in all kinds of seafood. It is produced by bacteria as a part of their normal metabolism, and it acts as a defence mechanism against predators. When fish are exposed to high levels of histamine, they can become ill and even die.
The level of histamine in seafood depends on a number of factors, including the type of fish, the environment it was raised in, and how it was stored before being sold. For example, fish that are caught wild tend to have higher levels of histamine than those that are farmed. This is because wild fish are more likely to be exposed to bacteria and other toxins. Similarly, fish that are not properly refrigerated can cause histamine levels to rise.
While most people can eat fish without any problems, those with allergies to histamine may experience symptoms such as hives, itching, swelling, and difficulty breathing. In severe cases, anaphylactic shock may occur. If you have any concerns about your ability to tolerate histamine, it is best to speak with a doctor or allergist before consuming fish or other seafood.
Histamine poisoning is relatively rare, but it can be serious. If you believe you or someone you know has ingested too much histamine, seek medical attention immediately. Symptoms of histamine poisoning include nausea, vomiting, abdominal pain, and diarrhoea. In severe cases, low blood pressure and difficulty breathing may occur. Histamine poisoning can be very dangerous, so it is important to get medical help right away.
There are a few steps you can take to avoid histamine poisoning. First, be sure to buy fresh fish, like the best reef fish, from a reputable source. If you are unsure about the freshness of the fish, don't eat it. It is better to be safe than sorry. Second, cook fish thoroughly. Histamine is destroyed by heat, so cooking will kill any harmful bacteria that may be present. Finally, don't forget to refrigerate leftover fish properly. If you do all of these things, you should be able to enjoy your seafood without worry.
