Is Brushtooth Lizardfish High In Histamine

If you're a seafood lover, you might have heard concerns about histamine levels in certain types of fish. The Brushtooth Lizardfish (Saurida undosquamis) is one species that has been associated with high histamine levels. In this article, we will delve into the topic of histamine in fish and explore whether the Brushtooth Lizardfish is indeed high in histamine. Let's start by understanding what histamine is and how it is produced in fish.

Understanding Histamine in Fish

What is Histamine?

Histamine is a naturally occurring compound that is present in various foods, including fish. It is a biogenic amine that is produced by certain bacteria during fish decomposition. Histamine is also produced by the human body as part of the immune response system. While histamine has several important physiological functions, excessive levels in food can lead to adverse reactions in some individuals.

When histamine is released in the body, it can cause a range of symptoms such as itching, hives, flushing, headache, and in severe cases, difficulty breathing and low blood pressure. These symptoms are collectively known as histamine intolerance or histamine poisoning.

It is important to note that histamine intolerance is different from a fish allergy. While a fish allergy is an immune response to proteins in fish, histamine intolerance is a reaction to the histamine present in the fish itself. People with histamine intolerance may be able to tolerate certain types of fish that are lower in histamine content.

How Histamine is Produced in Fish

When fish are caught and not immediately chilled or properly stored, the bacteria naturally present on their skin and in their gastrointestinal tract start breaking down the fish's proteins, resulting in the formation of histamine. This process is known as histamine formation or histamine poisoning. The ability of bacteria to produce histamine depends on various factors, such as the specific species of bacteria, temperature, time, and storage conditions.

There are certain types of bacteria, such as Morganella morganii, Proteus vulgaris, and Klebsiella pneumoniae, that are known to produce histamine in fish. These bacteria are commonly found in the marine environment and can multiply rapidly if the fish is not handled and stored properly.

Temperature plays a crucial role in histamine formation. The bacteria responsible for histamine production thrive in temperatures between 15°C and 40°C (59°F to 104°F). Therefore, if fish is not stored at temperatures below 4°C (39°F), the bacteria can multiply rapidly, leading to higher histamine levels.

Time is another important factor. The longer the fish is left at improper temperatures, the more time the bacteria have to break down the proteins and produce histamine. This is why it is crucial to handle and store fish properly from the moment it is caught.

Storage conditions also play a significant role in histamine production. Fish that is stored in warm, humid environments or exposed to air for extended periods of time is more likely to have higher histamine levels. Properly packaging and storing fish in coolers or refrigerators can help prevent histamine formation.

It is worth noting that not all fish are equally susceptible to histamine formation. Some fish species, such as tuna, mackerel, mahi-mahi, and sardines, are more prone to histamine production due to their higher levels of naturally occurring histidine, an amino acid that bacteria convert into histamine.

In conclusion, histamine formation in fish is a natural process that occurs when fish is not handled and stored properly. Understanding the factors that contribute to histamine production can help ensure the safety of consuming fish and prevent adverse reactions in susceptible individuals.

Histamine Levels in Brushtooth Lizardfish

Factors Affecting Histamine Levels in Lizardfish

While histamine formation can occur in any fish species under improper storage conditions, certain factors can influence the likelihood of higher histamine levels in Brushtooth Lizardfish. These factors include the temperature at which the fish is handled, the time elapsed between catch and proper chilling, and the hygiene practices during processing and storage.

Let's explore these factors in more detail. The temperature at which the fish is handled plays a crucial role in histamine formation. Brushtooth Lizardfish are particularly sensitive to temperature changes, and if they are not properly chilled, histamine levels can increase rapidly. Therefore, it is essential to handle these fish with care and ensure they are promptly stored in a cool environment.

Another factor that affects histamine levels in Brushtooth Lizardfish is the time elapsed between catch and proper chilling. The longer the time between catching the fish and chilling it, the greater the chance of histamine formation. This is because bacteria present on the fish can convert the amino acid histidine into histamine if given enough time. To minimize histamine levels, it is crucial to chill the fish as soon as possible after catching.

Hygiene practices during processing and storage also play a significant role in histamine levels. If the fish is not handled and stored in a clean environment, bacteria can proliferate, leading to increased histamine production.
