Toxoplasma gondii is one of the important zoonotic parasite of worldwide zoological and geographical distribution. In this paper, Toxoplasma antibodies were investigated among workers (21) and slaughtered animals (258) in Tanta abattoir. The indirect haemagglutination test (IHAT) was positive among workers (52.4%) at titers 1/64, 1/256, 1/512 and slaughtered animals (44.1%), at titers > 1:64. The indirect fluorescent antibody test (IFAT done for animals only) was positive (48.8%) at titers 1/40. Histopathological study on infected prescapular lymph nodes of the examined animals showed different clinical pictures, which coincided with the serological results. It was concluded that meat should not be consumed uncooked or undercooked.
