Method for verifying sterilization rate of ultraviolet disinfection box

The invention discloses a method for verifying the sterilization rate of an ultraviolet disinfection box. The method comprises the following steps of firstly treating and sterilizing various culture media in a high-temperature and high-pressure steam furnace for later use, and preparing sodium chloride diluent and eluent with the concentration of 0.9%; secondly sterilizing the surface of an objectto be in a sterile state; thirdly preparing a bacterial suspension, sucking the prepared bacterial suspension to the position, which is the most difficult to sterilize, on the surface of the sterilized object, and preparing a bacterial tablet; and fourthly carrying out testing of a test group and a positive control group of the ultraviolet disinfection box on a contaminated object, obtaining thebacterial count, and finally judging whether the bacterial count is qualified or not according to the sterilization rate. The sterilization rate verification step is carried out to achieve the beneficial effect of accurately a
