Occurrence of “Milk Spot” due to Scaris Suum on Liver of Pigs Slaughtered at Zuru, Nigeria

During the period of March 2010 and February 2011 inclusive, 105 pigs grouped as adults and youngs at various designated centers in Zuru, Nigeria, were examined during routine meat inspection at the slaughtered slabs for “milk spots” on the liver. The examination of the intestines for adult worms of Ascaris suum was similarly carried out to correlate the findings on the liver. Sixty-three (60%) of the pigs examined had milk spots. The infection by ages and sex were statistically insignificant. Infection in the males was greatly lower compared with that observed in the females. It is concluded that ascariasis is prevalent among pigs reared in Zuru, Nigeria, apart being a management problem, it is also of an economic significant due to the liver condemnation and retarded growth that may hinders the productivity.
