A video of a live rodent in a sushi display chiller at a branch of the Japanese supermarket chain Don Don Donki in Hong Kong has sparked concerns over food safety and hygiene standards in the city.

The footage, posted on the social media platform Threads on Thursday, captured a grey rat scurrying across pre-packed boxes of sushi in a chiller at a supermarket, which some users identified as the Don Don Donki branch in Tuen Mun Town Plaza.

In the 20-second clip, a male shopper carrying a tote bag is seen flinching and backing away from the counter in shock after spotting the rodent, which climbs across boxes of sushi and the inner edges of the chiller before disappearing into a gap in the unit.

“That rat is freaking huge. I never want to buy Donki’s sushi ever again,” the user who posted the video wrote.

The South China Morning Post has contacted Don Don Donki and the Food and Environmental Hygiene Department for comment.

The post sparked widespread revulsion among online users, with some vowing to boycott the chain’s sushi and many others lamenting the government’s ineffective efforts to control the city’s rodent problem.
