Identificación histopatológica de parásitos intramusculares en bovinos faenados en el cantón Loja

Abstract

Abstract: This study examines the presence of intramuscular parasites in slaughtered cattle, aiming to identify histopathological alterations that may compromise food safety and productive performance. Muscle samples from the heart, diaphragm, intercostal muscles, and skeletal muscle were collected and processed using conventional histological techniques with hematoxylin and eosin (H&E) staining. Microscopic analysis revealed structures compatible with Sarcocystis spp., characterized by intramuscular cysts and associated tissue damage. These findings highlight the need to strengthen sanitary controls during slaughter processes and to promote better practices in livestock production to reduce contamination risks. Early detection of these parasitic infections contributes to improving meat quality and ensuring food safety throughout the production chain. The results underscore the importance of continued research on the impact of intramuscular parasites on animal health and public health.
