What symptom would suggest trichinosis when interviewing a client with a suspected worm infection?

The symptom that suggests trichinosis is the ingestion of undercooked pork. Trichinosis is caused by the parasite Trichinella spiralis, which is commonly found in undercooked or raw pork. When humans consume infected meat, the larvae can invade the intestinal wall, leading to various symptoms, including gastrointestinal distress, muscle pain, and fever.

Undercooked beef, while it may be associated with other parasitic infections, is not a typical source of Trichinella; therefore, it does not indicate trichinosis. Exposure to contaminated water and contact with infected animals pertain to different parasitic infections and do not specifically link to trichinosis. Thus, the ingestion of undercooked pork is the critical factor that indicates a potential trichinosis infection.
