The surveillance of phycotoxins in marine shellfish. The REPHY network: objectives, strategies and primary results One of the objectives of REPHY (network for phytoplankton and phycotoxin surveillance) is to monitor toxin-producing micro-algae species in the marine environment that are likely to accumulate in seafood products, and to screen for these toxins in shellfish. This surveillance is undertaken in the framework of the European regulations. Three groups of toxins are thus monitored and are associated with three genera of toxic phytoplankton: (i) Dinophysis, a producer of the okadaic acid (with diarrhoeic effects) and pectenotoxin families of toxins; in the same group of so-called “lipophilic toxins”, two other families of regulated toxins are directly screened for in shellfish without referring to the phytoplankton that produces them: azaspiracids (with diarrhoeic effects) and yessotoxins; (ii) Alexandrium, a producer of toxins from the saxitoxin family (e.g. paralytic toxins, PSP); (iii) Pseudo-nitzschia, a producer of toxins from the domoic acid family (e.g. amnesic toxins, ASP). Lastly, another family that is not currently regulated is also monitored in the Mediterranean: palytoxins, produced by Ostreopsis. The operational implementation of REPHY relies on eight Ifremer laboratories spread out along the French coast, which among other things take water and shellfish samples and analyse, store and distribute results. Toxins in shellfish are detected and quantified by official analysis methods. Lipophilic toxins are found yearly in shellfish in several regions of France, while toxins from the saxitoxin family have rarely been observed since 2005. As for toxins from the domoic acid family, they primarily affect scallops as well as other shellfish in various regions.
