The goal of this study was to examine the knowledge and practice of food handlers in district two of Tehran.Methods: A cross sectional descriptive- analytical study was designed and data were collected via questionnaires. The reliability of the questionnaires were measured using Cronbach's alpha and Intra-class correlation obtained from test and re-test in an interval of ۱۰ days. The reliability indices of the questionnaires were found to be above ۷۰%, which were acceptable. The participants were selected by a simple random method (n=۳۹۰). Correlation coefficient was used for analysis.Results: The highest number of male participants, with diploma education belonged to the age group of ۲۰ to ۲۹ years old with a job experience of two to five years and more than ۵۰% of them had passed the public health course. The results showed that there was a significant relationship between knowledge and practice (P<۰.۰۰۱). In knowledge section ۲۱۵ (۵۵.۳%) of respondents were at middle level. About the practice, although ۱۹۵ (۵۰%) of participants were placed at a good level, in some cases, such as how to find out the optimal temperature for cooking burgers and chicken, the right way to defrost food and the time needed to reheat the food were found lacking.Conclusion: Knowledge and practice in food handlers must be improved specially about the importance and role of temperature in food safety.
