What happened with the Luckin coffee worm complaint?

A consumer in Zhejiang says she found small white worms in a Luckin Coffee drink bought at a newly opened Jiaxing store. The cup stayed sealed until she inserted the straw, and the objects were spotted only after more than half the drink was gone. She contacted Luckin customer service but has not received a reply.

The coffee was made around 11:20 a.m., and the customer started drinking after noon, initially in dim indoor light before seeing the moving objects outside in daylight. Online commenters debated the cause, with some suggesting fly eggs and others pointing to contamination from a drink left standing. The original post has since been hidden.

Recently, a netizen from Zhejiang posted a video on social media claiming to have drunk several small white wriggling worms in a Luckin Coffee drink, sparking widespread attention. According to the netizen, the coffee was bought by a friend at a newly opened Luckin store in Jiaxing, and the foreign objects were only discovered after more than half of the drink had been consumed. The video shows worms not only crawling slowly on the cup lid, but also similar small white objects floating in the dark coffee liquid. After the incident was exposed, netizens discussed where the worms came from, with some speculating they were hatched fly eggs and others questioning whether the coffee had been left too long and become contaminated. The poster stressed that the cup had remained sealed the entire time, making it difficult for flies to get in. As of now, the netizen has contacted Luckin customer service but has not yet received a reply.

Yesterday afternoon, a netizen whose IP location showed Zhejiang uploaded a video, saying that after drinking most of a Luckin Coffee purchased that morning, they discovered several small white worms swimming in the cup, shown in a wriggling state. Once the video was posted, it quickly drew a large amount of discussion and sharing among netizens. (Currently, the post has been hidden by the publisher.)

Judging from the video footage, about 80% of the coffee had been consumed. The suspected worms were not only moving slowly on the surface of the cup lid, but the same small white objects were also floating in the dark liquid.

According to the netizen, the drink was bought for her by a friend, and the ordering store was located in Jiaxing, a Luckin that had not been open long. It was made at about 11:20 a.m. that day, and she began drinking it after 12 p.m. Before inserting the straw, the coffee had remained completely sealed.

Recalling how she discovered the foreign objects, she said she had initially been drinking in a dimly lit indoor place, so she did not pay close attention. It was only in the afternoon, after going outside into bright light, that she saw the situation in the video. She immediately filmed a video as evidence and called the relevant complaint hotline.

In response, many netizens speculated that if the order had been a bayberry Renabing, then the "worms" in the drink most likely came from the bayberry pulp in the ingredients. But the blogger responded that what she ordered was a coconut water iced Americano, so that possibility could be ruled out.

Many netizens believed that the white wriggling foreign objects looked like fly eggs. The reason they were not discovered in the coffee at first and only "appeared" after some time was very likely that they had been hidden in the gap of the cup lid before serving, then later fell into the coffee and hatched into small white larvae within a few hours.

However, some netizens noticed a detail: since it was an iced drink, there should logically have been water droplets from melting ice on the cup wall, but the drink in the video was clearly at room temperature. Therefore, the foreign objects were very likely due to the coffee being left for too long, allowing flies to take the opportunity to fly in and lay eggs.

In response to these questions, the video poster explained that all the white foreign objects were found inside the cup, and fly eggs could not be ruled out, since such situations are impossible to guard against completely. As for whether the coffee had been contaminated by the outside because it was left too long, she said she normally has a habit of wiping the cup, and after inserting the straw she also kept the sealing sticker to cover the gap. When she discovered it, only a few hours had passed since pickup, so flies could not have gotten in at all.

As of press time, the video poster had contacted Luckin customer service and reported the situation, but had not yet received a reply.

The source of the larvae remains full of questions. Whether they were already in the cup at the time of purchase or fell into the cup after purchase still requires further explanation from the person involved or from Luckin.
