Article Synopsis
- Paralytic shellfish toxins (PSTs), which pose a public health risk from bivalve molluscs, must be kept below a regulatory limit of 0.8 mg saxitoxin per kilogram of shellfish meat to ensure safety for consumers.* -
- An interlaboratory study with 16 labs tested the Neogen immunological screening test for detecting PSTs in mussels and oysters, showing high detection probability rates close to the regulatory threshold.* -
- The Neogen test is acceptable for regulatory use in oysters but shows inconsistent results for mussels, particularly due to variability in detection reliability at the required levels.*
Detection of paralytic shellfish toxins (PSTs) in bivalve shellfish by analytical methods is complicated and costly, requiring specific expertise and equipment. Following extensive blooms of Alexandrium tamarense Group 1 in Tasmania, Australia, an investigation was made into commercially available screening test kits suitable for use with the toxin profiles found in affected bivalves. The qualitative Neogen rapid test kit, with a modified protocol to convert gonyautoxins GTX1&4 and GTX2&3 into neosaxitoxin and saxitoxin (STX), respectively, with higher cross-reactivities, was the best fit-for-purpose.
