C. elegans is a non-hazardous, non-infectious, non-pathogenic, non-parasitic organism. It is small, growing to about 1 mm in length, and lives in the soil—especially rotting vegetation—in many parts of the world, where it survives by feeding on microbes such as bacteria. It is of no economic importance to man.How do you test for trichinosis?
To confirm the diagnosis, your doctor might use these tests: Blood tests. Your doctor may take a blood sample and test it for signs suggesting trichinosis — an increase in the number of a certain type of white blood cell (eosinophils) or the formation of antibodies against the parasite after several weeks.How do you get Trichinella spiralis?
Trichinellosis also called trichinosis results from roundworms (nematodes) from the genus Trichinella. It is a parasitic infection. It is caused by consuming undercooked or raw meat (usually pork). Trichinella spiralis species is the common cause of human disease by eating raw or undercooked pork.How do humans get hookworms?

Both larval and adult forms of T. spiralis can parasitize humans as the definitive host but later they become the intermediate host when the larvae are established in the muscles.What do Trichinella spiralis eat?
Ingestion of the encysted larvae perpetuates the cycle. Rats and rodents are primarily responsible for maintaining the endemicity of this infection. Carnivorous/omnivorous animals, such as pigs or bears, feed on infected rodents or meat from other animals.What is the common name for Trichinella spiralis?
