The common cuttlefish (Sepia officinalis) is a popular food source, and it is often adulterated with other cephalopod and sepia species. A new, low cost, real time polymerase chain reaction (PCR) method can be used on fresh, cooked, grilled, frozen and canned preparations of Sepia officinalis, producing quick and highly reliable results. In this study, 25% of the samples were found to be different cephalopod species, and not Sepia officinalis.
