Mussels, oysters, scallops and clams might be ingredients for fine cuisine, but they can also be a recipe for diarrhetic shellfish poisoning (DSP). That’s a gastrointestinal illness people can get if those tasty morsels contain marine toxins.
Now, researchers are reporting in ACS’Journal of Agricultural and Food Chemistry the development of a portable, inexpensive device that can quickly and easily screen freshly caught shellfish for these substances.
DSP is caused by eating shellfish that have accumulated okadaic acid (OA) or related marine toxins. Algal blooms – commonly referred to as “red tides” – can produce these substances, which shellfish can accumulate through filter feeding. Because cooking the shellfish does not destroy the toxins, several regulations are in place to prevent the sale and consumption of tainted shellfish. To comply with these regulations, the current practice is to send samples to labs that use expensive, technically intense and slow tests. Waqass Jawaid and colleagues set out to develop an inexpensive, easy-to-use and portable device that maintained the rigorous testing standards of off-site labs but could quickly test shellfish on boats and at other remote locations.
The researchers adapted a test called a lateral flow immunoassay (LFIA), which is like a home pregnancy test strip.
This LFIA combines simple test procedures with an antibody previously shown to specifically bind to three OA toxins. The small, portable device can accurately screen for presence of these substances in less than 20 minutes on a boat, before it goes further into the supply chain. If the test is positive, then the shellfish would not be sold. If the LFIA readout is negative, then an additional, easy-to-use test could be conducted dockside for “total toxins,” which would include detection of a fourth type of OA.
