Street food is a weak link in food safety supervision, a topic of academic study for many years. In addition to offering convenience for many, millions of low-income people rely on street food for their livelihood, which has a significant positive impact on the economies of many developing nations. Although it is crucial, street food safety has received little research in China. As a result, a typical Chinese city was chosen as the research subject in order to evaluate consumer behaviors, street food vendors’ knowledge, attitudes, and street food safety using questionnaires based on earlier studies, while also taking into account China’s unique characteristics and any reasonable impacts found in earlier studies, such as increased income, work experience, licenses, and locations. The knowledge and attitude test on food safety was in line with Chinese national standards. Three main areas were covered in the surveys and statistical analysis in order to evaluate people’s knowledge of and attitudes toward food suppliers and consumers. Information about gender, age, income, education, training in food safety, and particulars about the work experience of suppliers. Food safety knowledge includes suppliers’ and customers’ awareness of pathogens that can cause food poisoning, food and personal hygiene, high-risk populations, and proper cleaning. The characteristics and behaviors of the subjects were determined using a list of food handling behaviors. The findings indicate that most street food vendors operate in unhygienic settings and generally have poor food handling procedures. The High-tech Industries Development Zone had the fewest street vendors who were knowledgeable about food safety, which is probably because these areas are situated in rural-urban fringe zones with generally low educational levels.
