SIMPLE TESTS for shellfish toxins Shellfish – Neogen Europe Ltd
RAPID, RELIABLE AND ACCURATE RESULTS
Without being tested for toxins, these mussels could pose a serious health risk N
eogen Europe Ltd has added to its compre- hensive range of
tests for the seafood indus- try with the introduction, last summer, of rapid tests to detect the toxins that cause amnesic shellfi sh poi- soning (ASP) and diarrhetic shellfi sh poisoning (DSP). The European headquar- ters of Neogen Europe is based in Ayr, on the West Coast of Scotland and house over 150 employees. Neogen’s new Reveal®
detects ASP-causing toxins at a level of 20 parts per million (ppm), and Reveal 2.0 for DSP detects DSP- causing toxins at 160 parts per billion (ppb). Both are one-step rapid tests, and
20
are compatible with US Food and Drug Administra- tion (FDA) and European Union Commission permit- ted levels.

QUICK AND EASY Both new shellfi sh toxin tests offer easy extraction processes, meaning they are on-site fi eld tests capa- ble of being used on a boat, and are used with Neo- gen’s innovative AccuScan® Pro Reader that provides consistently accurate and reliable results.
‘The combination of the
new tests and test reader provide an unparalleled ease in achieving consist- ently accurate results when testing for these toxins,’ said Neogen Europe’s Steve Chambers. ‘The AccuScan Pro Reader completely eliminates the variance in interpreting test results that can exist when only using a visual appraisal, es- pecially with inexperienced testers. It also provides a very easy method of storing and analysing test results — which is becom- ing increasingly required
‘These new tests provide consistently accurate results’
as many nations move to reduce the risk posed by these shellfi sh toxins.’ Toxins that cause ASP
are produced by toxi- genic diatoms of the genus Pseudo-nitzschia, and primarily include domoic acid (DA). In addition to contamination of seafood, these marine biotoxins can result in human and marine wildlife mortality. The clinical toxicological effects attributed to DA can include: permanent loss of short-term memory, nausea, vomiting, headache, disorientation and loss of balance. Most countries have currently established a maximum permitted level of 20 mg DA per kg whole shellfi sh (20 ppm).
Toxins that cause DSP include the okadaic acid (OA) group of toxins. OA is produced by marine dinofl agellates such as Di- nophysis, and has structural analogs referred to as the dinophysistoxins (DTXs). Clinical toxicological effects attributed to DSP following consumption of con- taminated seafood includes diarrhoea, nausea and vom- iting. The established EU maximum permitted levels are 160 µg OA equivalents (OA, DTXs, pectenotoxins) per kg shellfi sh meat (160 ppb). FDA action limits are 160 µg (160 ppb) OA equivalents (OA, DTXs) in shellfi sh. Reveal 2.0 for DSP’s rapid screen is vali- dated to detect OA, DTX1
