By analyzing the food additive crisis of Haitian Taste in 2022, we discuss the reasons for the failure of its crisis public relations, and at the same time propose how to carry out effective crisis management and public relations response and other related strategies, to provide lessons for future enterprises. This incident fully demonstrates that, in today's increasingly efficient information dissemination, enterprises must update their crisis response strategies, meet public needs promptly, and regain users' trust through openness and sincerity to minimize losses.
