ABSTRACT
Sarcocystis masoni n. sp. (known as "S. lamacanis") infects alpacas affecting their productivity and can cause a food poisoning syndrome in humans by consuming contaminated, undercooked cardiac muscle. There are few studies estimating the prevalence of this parasite in alpacas, although this information is crucial for the control and prevention of sarcocystosis. This study aimed to determine the frequency and density of Sarcocystis masoni n. sp. in the heart of alpacas in Huancavelica, a province of the Andean region of Peru. Heart samples were taken for histopathology from 104 alpacas slaughtered at the municipal slaughterhouse of Huancavelica, the official abattoir in the Huancavelica district. No macroscopic sarcocysts were observed. All alpacas (100%) had microscopic sarcocysts of Sarcocystis masoni n. sp., with no inflammatory reactions. The alpacas showed an average sarcocyst density of 60.8 ± 23.3/mm2. Sarcocysts density was significantly higher (p < 0.05) as the age of the animals increased. In addition, sarcocysts density was significantly higher (p < 0.05) in male animals aged 4 and 5 years compared to females of the same age. These results confirmed that heart sarcocystosis is highly endemic in Peruvian alpacas. Therefore, it is recommended that alpaca hearts be well-cooked at the time of consumption. The present study showed current data and contributes to the knowledge of this parasitosis. Studies of this nature are necessary because they are the basis for developing animal health programs.
