1 Swedish canned herring Canned herring is a traditional Swedish food. Processed herring is put into cans and allowed to ferment naturally. It is a canned food that exudes a foul odor and tastes sour.

The most distinctive feature of fermented herring is its ubiquitous, persistent stench.

People who have never eaten pickled herring often cover their noses because of its pungent stench. It is reported that the Swedish government also prohibits the opening of canned herring in residential areas.

Such cans are also not allowed on international flights because changes in air pressure may cause the cans to rupture, with serious consequences.

Its odor is equivalent to 300 times that of natto.

2. Italian maggot cheese Casu Marzu is a cheese deliberately stocked with live maggots.

After a high degree of decay and decomposition, it is made into a stink bomb that is drilled by fly larvae and constantly leaks water.

This cheese is soft and has a creamy texture.

Casu Marzu means "rotten cheese", or you can just call it "maggot cheese".

Popular in the Italian island of Sardinia, it starts with a large chunk of locally sourced goat cheese and then leaves it to go rancid beyond the norm.

Then pour the cheese fly larvae on top, and the acid secreted by the eggs will reduce the fat content of the cheese, eventually turning it into a soft, almost liquid substance.

By the time it's ready to eat, a good piece of maggot cheese will contain hundreds or thousands of larvae.

The scariest thing is that if you don't like eating maggots when eating cheese, the method is also very simple. Slap the cheese, and the disturbed maggots will jump up to 15 centimeters high. At this time, you only need to cover the cheese with your hands to prevent them from going back.
