ABSTRACT
In the second part of the study an attempt was made to reduce toxin content of contaminated shucked mussels collected during the diarrhetic shellfish toxin (DSP) episodes of 2007 and 2009 in Greece using ozone treatment. Ozonation resulted in toxin reduction in the range of 6-100%, 25-83%, and 21-66% for free OA, OA esters and total OA respectively. Percent reduction of OA content was substantially higher in homogenized mussel tissue as compared to whole shucked mussels. Upon optimization, ozonation shows promising potential for commercial DSP detoxification purposes.
