Seasonal dynamics and the distribution of dinophysistoxin-3 (DTX-3) in organs of mussel Crenomytilus grayanus, collected in 2013 in Peter the Great Bay, Sea of Japan, were determined. Active toxin forms (OA, DTX-1/2) concentrated in digestive glands (60–80%), whereas non-active 7-O-acyl derivatives (DTX-3) were more abundant in edible soft tissues (more than 80%). Possible mechanism of fast removing of DTX-3 from the digestive gland and accumulation of DTX-3 in the soft tissues is supposed. •Relative concentration of DTX-3 in organs of C. grayanus was compared.•Hepatopancreas generally contained less then 20% of DTX-3.•Edible parts of mussel contained more then 80% of DTX-3.
