Trichinella spiralis

Trichinella spiralis is a parasitic nematode that causes trichinellosis, a disease transmitted by consuming raw or undercooked meat from infected animals. In humans, the pathogen is mandatory notifiable according to the Infection Protection Act.

Causes, Symptoms, and Prevention

Trichinella spiralis is a small nematode worm that typically infects pigs but can also infect other mammals, including humans. The parasitic infection occurs through the consumption of raw or undercooked meat contaminated with the infectious larvae of the parasite.

Once infected meat is consumed, the larvae settle in the host's intestines, where they mature into adult worms. These adult worms produce larvae that then enter the bloodstream and nestle in the muscle tissue, where they form cysts.

Preventing trichinellosis mainly involves avoiding the consumption of raw or undercooked meat. Adequate cooking of meat at temperatures above 71°C can kill the larvae, significantly reducing the risk of infection. Adhering to hygiene standards during food preparation and handling meat can also help minimize the risk of trichinellosis infection.

Further informations

Trichinella spiralis

Trichinella spiralis is a small parasitic nematode worm.

The transmission of Trichinella spiralis occurs through the consumption of raw or undercooked meat contaminated with the larvae of the parasite. Pigs are the most common carriers of Trichinella spiralis.

The symptoms of trichinellosis can vary depending on the severity of the infection. Symptoms may include:

Early symptoms (1-2 days after infection):

  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain

Later symptoms (1-2 weeks after infection):

  • Fever
  • Fatigue
  • Muscle pain
  • Swelling in the face, especially around the eyes

Severe cases may include:

  • Heart palpitations
  • Difficulty breathing
  • Neurological problems

  • Consuming raw or undercooked meat contaminated with Trichinella spiralis significantly increases the risk of trichinellosis infection. Risky meat types include pork, wild boar meat, bear meat, and other wild game meats. 
  • The way meat is prepared is crucial. Ensuring that the meat is adequately cooked or frozen kills the parasites and reduces the risk of infection.
