Incidence of Brucella Species in Slaughtered Food Animals and its Edible Offal at Beni-suef, Egypt

This work was done to determine the incidence of brucella species among slaughtered food animals and their edible offal at Beni-Suef abattoir, Egypt .A total of 80 positive brucella slaughtered food animals was used in this study. The collected edible offal of these animals included liver, spleen, kidney, lung, hearts and lymph nodes. Samples were separately collected in sterile polyethelene bags. The collected samples were bacteriologically and histopathologically examined for the presence of brucellae species. Positive samples were subjected for boiling and roasting. Results showed that brucella melitensis and brucella abortus could be detected with various percentages in edible offal whereas the incidence of brucella melitensis was greater than brucella abortus. The histopathological reactions for brucella melitensis showed different granulamatous reaction in spleen, liver and lymph nodes. Boiling could efficiently eliminate brucella melitensis from edible offal, but it could be detected after roasting. In conclusion, edible offal of brucella infected animals could constitute public health hazard. .Moreover, the incidence of brucella during the period 2004 to 2007 in cattle, buffaloes, sheep and goats was monitored.
