Abstract：Objective To evaluate the hygienic status and nutrient value of food in Wuhan's street under the background of the “street stall economy” in the post COVID-19 epidemic era. Methods One food street was randomly selected from Wuchang, Jiangan and Jianghan districts of Wuhan, respectively. Then three street stalls were selected from each street according to barbecue, frying, steaming, baking, cold dressing, and beverages food categories for hygiene evaluation. 52 kinds of mainstream street-vended foods/beverages were identified by the Street Food Preference Questionnaire. The Nutrient-Rich Foods index(NRF6.3) was calculated to evaluate the nutrient value. Results The average hygiene score was 71.96. 96.3% of the stalls did not mark the source of food ingredients and 59.26% of the stall workers did not wear gloves and masks. The NRF6.3 of street food ranged from-39.08 to 80.19. Among 52 kinds of foods, the contents of dietary fiber in 3 kinds of street foods, vitamin A in 2 kinds of street foods, vitamin C in 4 street foods, and calcium in 2 kinds of street foods had reached the recommended nutrient intakes of adults(based on dinner standards). The amount of energy in 8 kinds of street foods, added sugar in 14 kinds of food street, fat in 15 kinds of food street, and sodium content in 31 kinds of food street had exceeded the daily intake limit of adults(based on dinner standards), and the sodium content in 13 foods had exceeded the whole daily intake limit. Conclusion The overall hygiene of street food is good in Wuhan City, while some hygiene problems still exist, including unclear sanitary signs and poor food processing environment. Furthermore, the nutrient value of street catering food is not satisfactory, with high fat and sodium content and insufficient dietary fiber and multivitamin.
