Ma Liu Ji's hot and sour noodles were exposed to have gone moldy, and all of the chain's stores were ordered to remove the product from their shelves by the authorities.

Recently, consumers in various places have reported that Costco, a membership-based store, has removed Maluji sour and spicy noodles from its shelves. A reporter from Nandu Bay Financial Society called six stores in Shanghai, Shenzhen, Suzhou, and Hangzhou, and customer service at all the stores confirmed that Maluji noodles had indeed been removed. At the same time, the Open Market Customer App currently does not show any related products from Maluji. Regarding the removal of Maluji noodles from the shelves, the person in charge of Open Market Customer told the reporter on July 25th, "During a recent routine quality inspection of products, we found fluctuations in the quality of this product. In accordance with quality control requirements, we have voluntarily suspended the sale of this product." The person in charge further stated that there is currently no specific timeline for when Maluji noodles will be put back on the shelves at Open Market Customer.
