          Abstract

          O Brasil se destaca na produção mundial de alimentos de origem animal, sendo que cada vez mais os mercados consumidores buscam alimentos seguros e inócuos para a saúde. Nesse contexto, torna-se fundamental a prevenção das zoonoses, que podem ser transmitidas através dos alimentos de origem animal, que muitas vezes são consumidos sem o devido preparo ou por populações mais vulneráveis. Nesta revisão bibliográfica, serão abordadas importantes enfermidades parasitárias de caráter zoonótico que ocorrem atualmente pela via de transmissão alimentar: a toxoplasmose, o complexo teníase-cisticercose, criptosporidiose, anisacose, difilobotriose e triquinelose.

          Translated abstract

          Brazil is one of the most important countries in the production of animal source foods, and the consumers are looking for safe and innocuous products for health. In this context, it is necessary to prevent zoonosis that can be transmitted by animal source foods, which are sometimes consumed without proper cooking or made by vulnerable populations. On this review, important parasitic zoonotic diseases will be covered, which currently occur by this transmission route: toxoplasmosis, taeniasis-cysticercosis complex, cryptosporidiosis, anisakiasis, diphyllobothriasis and trichinosis.

          Toxoplasmosis - a waterborne zoonosis.

          J Dubey (2004)
          Humans become infected with Toxoplasma gondii mainly by ingesting uncooked meat containing viable tissue cysts or by ingesting food or water contaminated with oocysts from the feces of infected cats. Circumstantial evidence suggests that oocyst-induced infections in humans are clinically more severe than tissue cyst-acquired infections. Until recently, water-borne transmission of T. gondii was considered uncommon but a large human outbreak linked to contamination of a municipal water reservoir in Canada by wild felids and the widespread infection by marine mammals in the USA provide reasons to question this view. The present paper reviews information on the biology of oocyst-induced infections of T. gondii in humans and animals and examines possible importance of transmission by water.

            A review of toxoplasmosis in cattle.

            J.P. Dubey (1986)
            Worldwide reports of natural and experimentally-induced Toxoplasma gondii infections in cattle are reviewed and tabulated. Serologic tests employed in most studies in the past are of suboptimal sensitivity for the diagnosis of T. gondii infection in cattle; therefore data need to be interpreted with caution. From the evidence available it is concluded that: T. gondii is probably not important in causing abortion or clinical illness in cattle but further experimental studies are desirable; T. gondii is eliminated quickly from bovine tissues; Whether beef plays a part in the epidemiology of toxoplasmosis is unresolved; Milk from T. gondii-infected cows is of negligible importance in the epidemiology of toxoplasmosis.
