Is canned herring harmful to the human body?

Canned herring is harmless to the human body as long as it is not eaten frequently. Canned herring is made through natural fermentation, but before fermentation, in order to prevent rotting and deterioration, the herring is usually boiled in light salt water over a low heat, and then canned for fermentation, so the odor and toxicity of the decomposition can be ignored.

We know that as long as food becomes rotten and smelly, it will produce bacteria and contain toxic substances, so naturally fermented food is generally not edible.

Canned herring is a fermented food that smells very bad. It is not advisable to eat too much of it. Eating too much of it can cause various discomforts to the body and cause harm to the body.

Why do canned herrings stink so badly?

The reason why canned herrings smell so bad is that during the canning process, only the fish head and internal organs are removed, and then they are cleaned and soaked in salt water for a period of time, and then boiled over medium-low heat before being canned and fermented naturally for several months.

The reason why canned herring smells so bad is because the production method of this food is quite unique. To make canned herring, you only need to catch the herring in spring, remove the head and internal organs and clean them, put them in salt water and cook them over medium and low heat, then they will be put into cans for natural fermentation. After several months of natural fermentation, they can be put on the market for sale.

Canned herring is one of Sweden's traditional delicacies. The biggest feature of this food is its stench that is hard to dissipate.
