For food safety, the concentrations and profiles of paralytic shellfish toxins (PSTs) and tetrodotoxin were examined in economically important scallops and bloody clams collected from the coast of the Miyagi Prefecture, Japan. PSTs were the major toxins in both species. The tetrodotoxin concentration in scallops increased in summer, although the highest value (18.7 μg/kg) was lower than the European Food Safety Authority guideline threshold (44 μg/kg). This confirmed the safety for tetrodotoxin in this area.
