what is use of studying health inspector? after twelth what degree I want to finish.

Health inspectors check the conditions of small to big food establishments to check if they follow the government guidelines for health regulations and codes. They check the sanitary conditions, make a detailed report and submit it to the health department. These include Hotels, motels, restaurants, youth camps, swimming facilities, etc. After 10th you should study Science in your 12th and study Bachelors in Occupational Health or Safety.
