Objective revealing the relationship between irradiation dose and inactivation ratio for cysticerci of Taenia solium in pork，determining the minimal dose for totally killing cysticerci and providing scientific evidence for setting up relevant hygienic standards of radiation. Methods After Taenia solium infected pork being treated with different irradiation doses; cysticerci were separated and incubated in fresh swine bile. The adjusted inactivation ratio was calculated according to the survival rate. Results There was a linear correlation between irradiation dose and adjusted inactivation ratio, the D₁₀ value was about 3.8kGy, and a totally killing could be achieved by 4.5kGy irradiation. Conclusion Irradiation at a dose of 4.5kGy could be applied as the maximum dose to inactivate cysticerci of Taenia solium in pork processing.
