I definitely can't eat. You should be talking about sheep brain echinococcosis. . . Sheep brain echinococcosis is caused by Taenia polycephala-polycephala. Adults parasitize in the small intestine of carnivores such as dogs, wolves and foxes, and their eggs are excreted with feces. Sheep are infected when grazing in the pasture seriously polluted by tapeworm eggs, and the larvae are parasitic in the sheep's brain. The larvae are cystic, and the cysts are filled with transparent liquid. The number of hexagamete cysts in cysts is often as high as 100~250, ranging from peas to eggs. The disease mainly affects sheep under 2 years old, and it also occurs in sheep over 2 years old.
