Liver flukes are flat, leaf-shaped parasites that primarily infect the livers of various animals, including cattle, sheep, and humans. These tiny creatures belong to a group called trematodes and can cause serious health issues, such as liver damage and inflammation. They often enter the body through contaminated food or water, particularly in areas where livestock are raised. Once inside, liver flukes can grow and reproduce, leading to a condition known as fascioliasis. Symptoms may include abdominal pain, jaundice, and fatigue. Preventing infection involves proper sanitation, cooking food thoroughly, and avoiding contaminated water sources, especially in regions where these parasites are common.
