In our country, imported Sudanese cattle are supposed to be an important source of high-quality
protein, which is obtained from their meat and milk. Consequently, strict veterinary inspection
should be applied to these animals in slaughterhouses before being subjected to human
consumption. This study aims to report the unusual migration of Taenia sagniata larvae (Cysticercus
bovis) to the liver of these animals and describe the pathological changes stimulated by them. In a
survey started in December 2020 and ended by October 2021, 1575 livers were carefully inspected
and examined, from which 172 specimens were condemned for different lesions. Prevalence of
cysticercosis was 1% (16/1575) among the totally examined livers. However, out of the rejected
specimens, cysticercosis occurred at a percentage of 9.3% (16\172). 5 livers showed a single cyst,
while 11 showed multiple. The total cyst count was 44, of which 28/44 (63.6%) were viable with thin
transparent walls and discharging of spotted scolex on incision. However, 16/44 (36.3%) cysts were
degenerated and appeared firm, pale yellowish, with firm consistency. The morphological appearance
of the liver varied from normal structure and consistency to swollen with rounded borders.
Histopathological analysis showed a fully developed bladder-like cyst with its invaginated scolex in
liver tissues resulting in necrotic changes in hepatocytes, fibrosis and inflammatory infiltrate. Due to
the significant risk of Cysticercus bovis to human health, meat inspection must be carefully
considered.
