Canned herring is "notorious" and I believe many people are familiar with it. It is said that it is called "the most smelly in the world". It combines the "essence" of all stinky smells such as stinky tofu, rotten eggs, swill, poop, sewer and so on.

The public calls it "biochemical weapons" in food.

Although it is very smelly, Sweden, its birthplace, "loves and hates" it. While constantly promoting canned herring to the world, it also restricts its production and market time and the way to open the can. In particular, it is not allowed indoors.

Why open a canned herring?

The editor goes with everyone to "find out".

Although canned herring is a local delicacy in Sweden, because of its special smell, the local government also has express regulations on its time to be put on the market. It is said that the third Thursday in August every year is the legal time for canned herring to be put on the market.

Time is not allowed to be sold.

The editor thinks it may be because it smells so bad. If it is sold all year round, the air in Sweden will be polluted.

?In addition, the Swedish government also stipulates that canned herrings are not allowed to be opened indoors. The editor believes that the odor concentration of the canned herrings may be too high. If the canned herrings are opened indoors and the air is not circulated and the odor persists for a long time, it may have a certain impact on the human body.

, so it is required to be opened outdoors to facilitate the circulation and dissipation of odor.

In addition, because of the special smell of canned herring, many countries do not allow it to be carried on board or even checked in. If the can ruptures due to high air pressure, the entire cabin will face an "attack" from this "biological and chemical weapon"

, so even those who have never eaten canned herring can imagine how smelly it is after reading the above requirements and regulations for canned herring.

So do you have the courage to try this kind of canned herring?
