Currently, there exists no specific and assimilated system of monitoring and investigation to diminish health and economic losses related to insufficient food safety system in Pakistan.

This study was conducted in various food production units in Lahore, among food handlers on the base of Knowledge, Attitude, and practice. In this study, overall Knowledge of food handlers were good, result was 85%. And Attitude score was 66% approximately result was good. However, Practice score was poor. Significance difference was seen between Knowledge and Practices with p value < 0.05. Moreover, Significance difference was seen between Attitude and practices with p value < 0.05. All this data concluded that implementation of  GMP’s, personal hygiene, HACCP, FSSC 22000 and other food related laws are essential to keep this world healthy.
