Abstract

Bovine cysticercosis is one of the zoonotic diseases caused by the larval form of bovine muscle infected with Taenia saginata. The carcass, which is slightly affected by cysticercosis, must be conditionally approved after specific treatment or totally condemned if treatment not available at abattoir. In this study, 100 meat samples were collected from normal carcasses and carcasses mildly affected by cysticercosis (50 samples each). The samples were analyzed for chemical composition and quality characteristics to compare normal meat with meat from cattle with cysticercosis. The protein, fat, and ash content of beef from animals slightly affected by cysticercosis revealed marginal changes compared to beef from normal carcasses. However, there was a significant increase in humidity as well as qualitative and quantitative changes in the amino acid profile and a reduction in the content of polyunsaturated fatty acids in the meat of cattle affected by cysticercosis. Meat from animals diagnosed with cysticercosis had TVB and TBA levels that were higher than normal but still within permissible bounds. In conclusion that meat from cattle suffering from mild cysticercosis is of lower quality and quantity than meat from animals in good condition. Further research is needed to study the effect of sex as a factor on the quality and chemical composition of meat recovered from bovine carcasses lightly infested with cysticercosis.
