Objective To understand the status of HBV infection and ALT level of practitioners in food industry and public place of Guangzhou,and provide a scientific basis for controlling HBV prevalence.

In view of the age distribution, the HBsAg positive rate of 30～ years old group was the highest (5.15%),and the HBeAg positive rate of the 30 years old group was the higest(1.61%).The differences between different age groups were statistical significance(P0.001). The HBsAg positive rate, HBeAg positive rate and the abnormal rate of ALT in males were obvious higher than those of famales(P0.001).
