Popis: Eosinophilic myositis in bovine striated muscle thought to be caused by a hypersensitivity reaction to the degradation of Sarcocystis tissue cysts, is a rare reason for carcase condemnation in the United Kingdom. This paper describes the identification of Sarcocystis cruzi associated with lesions of generalised eosinophilic myositis in three English beef carcases, by gross and histopathological examination followed by PCR with subsequent sequencing. Samples from two unaffected animals were also examined. Although sarcocystosis caused by S.cruzi is not considered a public health risk, the clinically affected carcases were deemed unfit for human consumption due to the extensive lesions affecting meat quality. We believe this to be the first report from the UK describing the molecular-based identification of Sarcocystis cruzi in meat affected and unaffected with eosinophilic myositis.
