The invention discloses a method for evaluating ingredients for alleviating food-borne enteritis based on a zebrafish juvenile imaging model. This method is based on the innate immune cell double-labeled strain and the acquired immune cell single-labeled Tg transgenic fluorescently labeled zebrafish model to establish a food-borne enteritis model. The visualization method of imaging effectively presents the behavior of various immune cells involved in the process of food-borne enteritis, and is used to evaluate the ingredients for alleviating fish food-borne enteritis. This method effectively shortens the evaluation cycle, fully demonstrates the effects of alleviating food-borne enteritis ingredients on innate and acquired immunity, and overcomes the shortcomings of traditional adult fish model tests, such as long test cycle and complicated operation, and avoids short-term immersion of juveniles. Fish can cause problems with systemic immune responses in mucosal tissues.
