Marketable mussels Mytilus galloprovincialis traded with commercial certification from production sites in Italy and abroad (France, Spain) were examined for the presence of Mytilicola intestinalis (Copepoda: Mytilicolidae) and Urastoma cyprinae (Turbellaria: Hypotrichinidae) from October 1994 to February 1996. The prevalence of M. intestinalis was 4.1% and 4.7% respectively in mussels from Lerici (La Spezia) and S. Pietro in Volta (Venice), whereas it rose to 57.9% in the samples from Spain. M. intestinalis was absent in mussels from Chioggia (Venice), Ganzirri (Messina), Taranto, Trieste and France. The prevalence of U. cyprinae varied considerably, ranging from 0.3% in mussels from Trani (Bari) to 33.2% and 86.3% respectively in those from Chioggia and Trieste. It was 85.7% in samples from France and 63.7% in those from Spain.
