What illness is caused by the parasite known as Trichinella spiralis?

1. Giardiasis

2. Trichinosis

3. Salmonellosis

4. Hepatitis

The correct answer is: Trichinosis

Trichinosis is an illness caused specifically by the parasitic roundworm Trichinella spiralis. This parasite typically infects humans through the consumption of undercooked or raw meat that contains Trichinella larvae, most commonly found in pork and wild game. Once ingested, the larvae can mature into adult worms in the intestines, leading to symptoms such as gastrointestinal distress, muscle pain, fever, and swelling of the face and eyes. Other options—like giardiasis, salmonellosis, and hepatitis—are caused by different pathogens, such as other parasites or bacteria. Giardiasis is due to the Giardia parasite, salmonellosis is typically caused by the Salmonella bacteria, and hepatitis refers to inflammation of the liver that can be caused by several viruses. Understanding the specific causative agents of illnesses helps in identifying risks associated with food safety and proper cooking methods to prevent infection.
