Not exactly. Because some professional countries stipulate that occupational health examination must be done. For example, the state requires employees of pharmaceutical production and trading enterprises to have an occupational health examination at least once a year, and they can only take up their posts with health certificates. It also stipulates the items of physical examination: blood routine, liver function, chest X-ray, color blindness and hand dermatosis. These inspection items are mainly to ensure that drugs are not polluted, ensure the quality of drugs, and be responsible to consumers.

The state stipulates that you must obtain a health certificate before you can take up your post. The types of jobs that must be examined every year are employees of food production enterprises and catering industry.

However, it is not absolutely impossible to contact posts that are harmful to health. Even in drug production, there are drugs that are harmful to health. For example, the production of anti-tumor chemotherapy drugs, no matter how good the protection, will also cause pollution to your body. So first find out what company you are going to apply for, whether there is any job harmful to your health, and whether you will be assigned to that position.
