8 pages, Street foods play an important role in the lives of urban population members in developing countries. The food industry provides many job opportunities. The food safety knowledge, attitude, and practices of vendors are important aspects, as these individuals provide food and nourishment at very low prices to people all over the world. Most street foods are unhealthy because of the high risk of contamination, which poses a serious threat to food safety. The present study aimed to assess the food safety knowledge, attitudes and practices of vendors and the most significant influencing factors of these aspects with the help of cluster analysis to categorize vendors. The present study focused on 100 vendors who were randomly selected from different locations in Lucknow city. The information was collected through a structured questionnaire using the KAP (Knowledge Attitude Practice) scale for food safety. Vendors were clustered on the basis of the KAP using two-step cluster analysis and a chi -square test to assess the impact of various personal factors on the KAP. The results of the study indicated that street vendors are significantly differentiated on the basis of qualifications, knowledge, attitude and practices. Awareness and training programs should be implemented to improve the food safety knowledge, attitudes and practices among vendors. Once food safety standards are acceptable, it will then be critical to ensure that poor people in developed cities such as Lucknow can earn a living through a "convenient" enterprise such as street food vending.
