Although the parasite has been documented in Atlantic mackerel (\n                    <jats:italic>Scomber scombrus<\/jats:italic>\n                    ) across parts of the Northeast Atlantic, its presence in mackerel landed in Ireland has not been previously confirmed. In this study, mackerel obtained from commercial landings were screened for signs of post-mortem myoliquefaction. Three individuals displaying characteristics of softening of the musculature were examined using light microscopy and molecular analysis. Microscopic examination revealed numerous spores consistent with\n                    <jats:italic>Kudoa-<\/jats:italic>\n                    like morphology.
