In vivo, after administration by gavage to mice and rats, okadaic acid has been reported to produce lesions in liver, small intestine and forestomach. Because several reports differ in the damage detected in different ...

Evaluation of the impact of mild steaming and heat treatment on the concentration of okadaic acid, dinophysistoxin-2 and dinophysistoxin-3 in mussels

Rodríguez Filgueiras, Inés; Alfonso Rancaño, María Amparo; Antelo Queijo, Álvaro; Álvarez, Mercedes; Botana López, Luis Miguel (MDPI, 2016-06)

This study explores the effect of laboratory and industrial steaming on mussels with toxin concentrations above and below the legal limit. We used mild conditions for steaming, 100 ˝C for 5 min in industrial processing, ...
