Videos have emerged of people licking bottles and dishes, sparking concern

 
Sushi train restaurants in Japan are under threat after customers found licking and touching food on conveyor belts.

Japanese police have arrested three people over “sushi terrorism”.

Last month, a video of a man licking a soy sauce bottle on a sushi conveyor went viral.

In the video, he can be seen squishing sushi dishes.

Since then, dozens of other videos are sparking public concern, such as people filming themselves touching sushi dishes passing by the conveyer belt.

One video, which emerged last month, showed a customer putting wasabi on another’s dish, while another person licked the presented chopsticks.

The viral trend has horrified many Japanese and spurred action from several conveyor-belt sushi chains.

Some eateries have even made the choice to stop operating their main attraction altogether – with sushi conveyor belts coming to a halt across the country.
