The aim of this study was to research whether there were paralytic and diarhetic shellfish toxins in mussels and oysters that were commercially-cought from aegian and marmara seas,and in case of presence,to evaluate whether these toxins were hazardous for human health,and to assert the seasons and regions in which these toxins were abundant. samples from 72 group of mussels and oysters which were collected in may,july and october were analyzed in the study. 'mouse biological method',which was accepted as the most certain test for such toxication tests,was used as the main method. the data showed that diarhetic shellfish toxins were not found in any region,but paralytic shellfish toxins may be found in izmir and balikesir during summer and at the end of spring. in addition,the amount of toxins did not carry risk for human health.
