A total of four cows entered the Fusion supermarket in Mui Wo, a rural town in southwestern Hong Kong, around 8 p.m. on February 7, the local Ming Pao newspaper reported .
Footage posted on Facebook showed three cows walking around Fusion's fresh fruit and vegetable section, appearing to be barricaded in by three shopping carts, while shoppers looked on and tried to take photos.
Three of them were still hanging around the store around 10:30 p.m. that night, even after the store shut for the night.
Fusion is the high-end version of the city's ubiquitous PARKnSHOP supermarket chain, and sells more gourmet food than some of PARKnSHOP's other chains.
The footage shows one of the cows rummaging through the bottom shelf of a fridge, while three others work through packets of oranges and grapes.
The Mui Wo area is home to around 30 cows and 40 water buffaloes, Ming Pao reported. The outlet said they have never entered stores before.
Andy Wong Man-hon, a district councilor, told the newspaper he was worried this incident would lead to more incidents of cows invading local stores.
The wild animals completely destroyed the fruit, and staff thoroughly cleaned all the surrounding shelves, Ming Pao reported PARKnSHOP representatives as saying.
Hong Kong a city known for its bustling nightlife and luxury mansions has been grappling with wild animals wreaking havoc on its way of life recently.
