To confirm further the effectiveness of canning process demonstrated previously a similar experiment was carried out using highly paralytic shellfish polish (PSP) -infested scallops. Toxic specimens of the scallop Patinopeceten yessoensis from Funka Bay, Hokkaido, were dissected into three parts-digestive gland (avergaed toxicity, 400MU/g), adductor muscle (3.5MU/g) and others (32MU/g), Each part was cut into cα. 0.1 com3 dice and processed according to the standrd canning procedures. In all parts, much of the toxicity was lost with retorting but some with heating (70°C, 20min) followed by washing. A steady reduction of the toxicity took place during storage of the canned products; after 30 days of storage, the toxicity scores of digestive gland dropped near or below the quarantine limit 4 MU/g. These observations indicate that canning might also be applicable for the scallops infested with PSP as high as 400 MU/g in digestive gland.
