At what temperature are the larvae of tapeworms and flatworms destroyed?

Hello doctor! Doctor let me ask if the parasites and eggs such as tapeworms, flatworms... can be destroyed at a temperature lower than -15°C? Ask your doctor for advice.

Hello! Normally, tapeworm larvae die at -2oC, but if at 0oC to -2oC it can live for nearly 2 months and at laboratory temperature also for 26 days. If you want to use raw pork, it must be kept at -10oC for 4 days to be sure.
Larvae are killed at 45 - 50oC. Therefore, a temperature of -15 degrees Celsius is not safe to kill parasites. To be safe, 1⁄2 kg of meat must be boiled for 1 hour. The larvae of the fluke live after 22 days of immersion in saturated brine.
Do not use products contaminated with tapeworm larvae, if cooked food thoroughly, although it does not cause disease, there are toxins secreted in food by larvae, which is not good for the digestive system, as well as the human body. People.
If there is a suspicion of parasitic infection, you should go to the hospitals of Vinmec Health System to perform a parasite test kit. If unfortunately, the disease is under control, it will be treated promptly and quickly.
Thank you for sending your question to Vinmec Health System. Best regards!
