Tapeworm (Taenia solium) Infection Prevention

Although Taenia solium has a global distribution, the highest prevalence is found in areas with poor access to adequate clean water and sanitation. Prevalence can also be high in areas that ingest raw or under-cooked meat. At this time, prevalence is highest in Africa, Asia, Latin America, East Europe, China, Pakistan, and India. Due to diagnostic limitations in certain areas, the true prevalence could be higher than current estimates.¹

The spread of tapeworm infections can be prevented with strategies that target all hosts. Humans are both definitive and intermediate hosts for Taenia solium. Pigs serve as intermediate hosts. Therefore, all pigs that have a tapeworm infection were infected by a human with taeniasis. Humans with taeniasis cause cysticercosis in pigs, themselves, and other humans.^2,3

To prevent Taenia solium infections, consider implementing these strategies:

• Test everyone with signs or symptoms of taeniasis.
• Treat and confirm eradication in all patients who test positive for a tapeworm infection.
• Wash hands thoroughly with hot, soapy after using the restroom and before and after handling food ⁴
• Wash all raw fruits and vegetables thoroughly⁴
• Properly cook foods, especially pork and vegetables⁴
  • Ground pork must be cooked to an internal temperature of 160 °F (71 ºC), according to Michigan State University
  • Pork roasts, pork chops, pork ribs, and other cuts must be cooked to an internal temperature of at least 150 ºF (65 ºC)¹
  • Neither pickling nor salt-curing pork ensures infection prevention¹
  • Use an accurate meat thermometer in the middle of the thickest part to test for doneness and ensure safety.⁵
• Freezing pork at a temperature of 23 ºF (-5 ºC) for at least 4 days kills cysticerci⁶
• Separate raw meat, poultry, seafood, and eggs from other foods from each other
• Keep different kinds of raw animal-based foods separate from each other
• Designate a cutting board for fresh produce and a separate one for raw meat, poultry and seafood. Never use the same cutting board for all foods.
• Never place cooked food on a plate or area that previously held raw food, including meat, poultry, seafood, eggs or raw vegetables
• Once a marinade or sauce has touched raw meat, bring it to a boil before consuming
• Store meat properly. Refrigerate or freeze it as soon as possible and keep cold at 40 °F or below in a refrigerator and keep hot at 135 °F or above
• Never let raw meat sit at room temperature for more than two hours.
• Never defrost meat at room temperature. Instead, thaw meat in the refrigerator, submerged in cold water, or in the microwave, and then cook immediately after thawing.⁵
• Ensure that preventive measures, including inspection, vaccination, and treatment, are up to date for all pig owners.^7,8
