The aim of the study was the sanitation and disinfecting llama meat naturally infected with macrocysts of Sarcocystis aucheniae through any of four physical methods: boiling (100 ºC for 10 min), baking (105 ºC for 65 min), frying and freezing (-20 ºC for 10 days). A lisis of macrocysts from treated and non-treated meats was prepared and inoculated (100 μg/kg of body weight, subcutaneously).into 30 rabbits of 4-5 months of age. Only rabbits of the positive control group (non-treated meat) died. Rabbits of the frozen meat group showed moderate toxicity signs. Furthermore, 13 puppies (2-5 months of age) were fed with 200 g of treated or non-treated infected llama meat. Puppies of meat-treated groups did not eliminate sporocysts in the feces as compared to puppies of the non-treated meat that had sporocysts after 14 days of the feeding. It can be concluded that boiling, baking, and fryin...

Con el objetivo de sanear y detoxificar la carne de llama infectada con Sarcocystis aucheniae se evaluó el efecto de los métodos físicos de cocción (100 ºC por 10 min), horneado (105 ºC por 65 min), fritura y congelado (-20 ºC por 10 días). La inactivación de la toxicidad de la proteína sarcocystina se evaluó en 30 conejos de 4-5 meses de edad que fueron inoculados s.c. con 100 μg de proteína/kg de peso vivo, obtenida de un lisado de macroquistes de S. aucheniae proveniente de carnes tratadas con cada método físico y de carne sin tratar. Únicamente los conejos del control positivo (carne sin tratar) murieron. Los conejos del grupo de carne congelada presentaron sintomatología tóxica moderada. La interrupción del ciclo biológico del S. aucheniae se evaluó en 13 perros de 2-5 meses de edad que fueron alimentados con 200 g de carne de llama tratada o sin tratar. Los per...
