Understanding Histamine in Fish

What is Histamine?

Histamine is a compound that is naturally present in the human body and plays a crucial role in various physiological processes. It is involved in regulating immune responses, neurotransmission, and the regulation of stomach acid production.

While histamine is essential for our bodies' normal functioning, it can also cause adverse effects when consumed in high quantities, especially for individuals with histamine intolerance.

Histamine intolerance is a condition in which the body is unable to break down histamine efficiently, leading to an accumulation of histamine in the bloodstream. This can result in symptoms such as headaches, flushing, hives, digestive issues, and respiratory problems.

How Histamine Develops in Fish

Fish, including smelt, naturally contain an enzyme called histidine decarboxylase. When fish are caught, the enzyme can convert the amino acid histidine into histamine through a process called decarboxylation. Histamine levels in fish can increase rapidly if the fish is not handled, stored, or processed correctly after being caught or harvested.

Factors such as temperature abuse, poor hygienic practices, and improper storage conditions can contribute to the development of histamine in fish.

Temperature abuse refers to situations where fish are exposed to temperatures that are too high, allowing the histidine decarboxylase enzyme to convert histidine into histamine at a faster rate. This can occur during transportation, storage, or even during the cooking process if the fish is not cooked thoroughly.

Poor hygienic practices, such as inadequate cleaning of fish or using contaminated equipment, can introduce bacteria that produce histamine. These bacteria, such as Morganella morganii and Proteus vulgaris, are known to be histamine producers and can thrive in unclean environments.

Improper storage conditions, such as storing fish at temperatures above 40°F (4°C), can also promote the growth of histamine-producing bacteria. When fish are not kept at the proper temperature, bacteria can multiply rapidly, leading to higher histamine levels.

It's important to note that not all fish have the same potential for histamine development. Some species, such as tuna, mackerel, and mahi-mahi, are more prone to histamine formation compared to others. This is due to their higher levels of histidine decarboxylase enzyme activity.

In conclusion, understanding how histamine develops in fish is crucial for ensuring food safety and preventing histamine poisoning. Proper handling, storage, and processing of fish are essential to minimize histamine levels and reduce the risk of adverse reactions in individuals with histamine intolerance.
