What Happened in the Latest Luckin Coffee Bug Incident?

A customer reported finding live maggots in a Luckin Coffee "Meteor" series drink after drinking more than half the cup. The store said surveillance footage showed no problems in operations or material storage, and offered three drink vouchers as compensation, which the customer refused. Market regulators have stepped in, and the customer has not received further official communication.

This is not the first bug-contamination controversy for Luckin Coffee; similar incidents were exposed last year. The case has drawn wide attention on social media and raised food safety questions for the beverage industry. The source of the maggots remains unclear, and the company has said it will help report the matter to customer service if the customer pursues it further.

Recently, a consumer exposed on social media that she found several still-wriggling live maggots in a Luckin "Meteor" series drink she had purchased—by which point she had already drunk more than half the cup. The store involved responded that surveillance footage showed no abnormalities in either operations or material storage, and offered three drink vouchers as compensation, which the customer explicitly refused. This is not the first time Luckin has been caught up in a bug-contamination controversy; several similar incidents were exposed last year. As the incident continues to escalate, market regulators have stepped in, and the consumer has yet to receive any further official communication. Food safety has once again become an unavoidable core issue for the beverage industry.

Truly disgusting! Bugs have been exposed in Luckin Coffee drinks yet again! And this time they're alive, wriggling maggots?!! yue~ 🤯

According to a video uploaded by a netizen on social media, she bought a cup of coffee at Luckin, and when she had drunk it down to less than half a cup, she unexpectedly discovered two still-moving maggots in the cup. After finding the problem, she immediately contacted the store, and Luckin's proposed solution was to compensate her with three drink vouchers. The consumer was not satisfied with this outcome and refused outright.

Once the news broke, topics such as #CustomerExposesSuspectedWrigglingBugsInLuckinCoffee# and #StoreRespondsToSuspectedBugsInLuckinCoffee# quickly sparked a large amount of onlooker attention and discussion across major social platforms.

According to reports from multiple media outlets, the person in charge of the store involved stated publicly: they had retrieved the surveillance footage from when the drink was made, and no abnormalities were found in any step from the operating process to material storage, and the source of the bugs remains unclear at present. The person in charge also said they were maintaining communication with the customer, and if the customer wished to pursue the matter further, they would help report it to the company's customer service.

From the content of the video posted by the customer, the sequence of events was roughly as follows: she initially ordered a cup of Luckin's Meteor series coffee, and the staff gave her a thin straw. After drinking more than half, she wanted to eat the toppings at the bottom of the cup, but found that the straw simply couldn't suck up those "meteor" ingredients, so she simply removed the lid. But no sooner had she opened it than she was shocked to see maggots in the cup—alive, and still wriggling! And there was more than one!

The screenshot below is the follow-up explanation posted by this whistle-blowing consumer the next day ⬇️

She mentioned: throughout the entire communication and negotiation process, the store owner never once said "sorry" or any word of apology—from beginning to end, it was she, the consumer, who took the initiative to approach the merchant...

In the comment section of the most popular related video, many netizens expressed shock and disbelief. Some commented: "I worked part-time at Luckin, the store was incredibly clean, hygiene requirements were extremely strict, my hands were almost washed raw," "No way, Luckin's hygiene standards absolutely crush its competitors," "Looks like someone's trying to take down Luckin lately," "I don't think it's very likely for bugs to appear in coffee"...

Some netizens also raised doubts: "With maggots this small, can you even see them on surveillance?" Others analyzed: "In this season, food spoils easily if you're not careful, and bugs and maggots appearing is normal." One netizen even shared their own experience: "The first time I drank Luckin, I also found bugs in it. The store also said there was no problem with their operations, and in the end they also said they'd give me vouchers"...

Worth noting! Last September, Luckin was also exposed for maggots being found in a drink—and there were as many as a dozen of them! Because of this serious drink hygiene problem, the Luckin store involved voluntarily suspended business and carried out a two-week disinfection and pest control treatment!!!

Going further back, last June, Luckin also made it onto Weibo's trending search list with the search term #WomanFindsBugsInCoffeeCustomerServiceSaysWillCompensateWithDrinkVouchers#! At the time, after the person involved found bugs in the drink, they reported it to customer service, who said they could compensate with 5 drink vouchers. The person felt this was inappropriate and called the 12315 hotline to file a complaint.

In fact, it's not just Luckin—similar hygiene incidents in the beverage industry as a whole are endlessly emerging. One saying always holds true: Food safety and hygiene must always be put first in the food and beverage industry; only then can a company become a true "winner"! ! (ennn~ yes, that's right~)

Regarding the incident mentioned at the beginning of the article, according to a report by The Paper, this consumer stated that as of this morning, she still had not received any further communication from Luckin officially. The Paper called the store involved for this, and the staff responded: today, the relevant evidence has been submitted to the local market supervision bureau as required, and the matter is still under negotiation and handling.
