Tapeworm eggs are typically shed in the feces of the definitive host, which can be humans or animals. These eggs can then contaminate the environment, including soil, water, and food sources. Transmission occurs when intermediate hosts, such as cattle, pigs, or fish, ingest these contaminated resources. Humans can become infected by consuming undercooked or raw meat containing the larvae, or by ingesting food or water contaminated with tapeworm eggs.
