Biosensors for Biotoxins Detection and Monitoring

Advanced Sensor Research, Volume 5, Issue 6, June 2026.
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...

Improved Isolation Procedures for Okadaic Acid Group Toxins from Shellfish (Mytilus edulis) and Microalgae (Prorocentrum lima)

Marine Drugs, 2020
Okadaic acid (OA) group toxins may accumulate in shellfish and can result in diarrhetic shellfish poisoning when consumed by humans, and are therefore regulated.

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...

Quantitation of diarrhetic shellfish poisoning toxins in Chilean Mussel using pyrenyldiazomethane as fluorescent labeling reagent

Biological Research, 2003
Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disease caused by lipid soluble polyether toxins produced by dinoflagellates and accumulated in shellfish.

Dinophysis Toxins: Causative Organisms, Distribution and Fate in Shellfish

Marine Drugs, 2014
Several Dinophysis species produce diarrhoetic toxins (okadaic acid and dinophysistoxins) and pectenotoxins, and cause gastointestinal illness, Diarrhetic Shellfish Poisoning (DSP), even at low cell densities (<103 cells·L−1). They are the main threat,

Evaluation of the study carried out by ANSES on the effectiveness of sanitary shucking of queen scallops (Aequipecten opercularis) contaminated by okadaic acid toxins

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract Following a request from the European Commission, EFSA evaluated the effectiveness of sanitary shucking of queen scallops (Aequipecten opercularis) contaminated with okadaic acid (OA) group toxins. Specifically, EFSA was tasked to evaluate a study conducted by the French Agency for Food, Environmental and Occupational Health & Safety (ANSES ...

Development of a High‐Sensitivity Electrochemical Biosensor for Domoic Acid and Its Cellular Impact on Human Stem and Neuron‐Like Cells

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Integrated workflow of domoic acid (DA) detection in seafood using a high‐sensitivity electrochemical biosensor and subsequent evaluation of DA‐induced cellular responses. (A) DA monitoring in seafood: Marine samples (European anchovy and mussels from the Marmara and Black Sea) were collected, extracted using a 1:1 methanol/water mixture, and analyzed ...

Acquired Phototrophy and Its Implications for Bloom Dynamics of the Teleaulax-Mesodinium-Dinophysis-Complex

Frontiers in Marine Science, 2022
The dinoflagellate Dinophysis is responsible for causing diarrhetic shellfish poisoning impacting shellfish aquaculture globally. Dinophysis species are invariably plastidic specialist non-constitutive mixoplankton (pSNCM), combining phagotrophy with ...

Safety of acute exposure to the food additive glycerol (E 422) from beverages

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract The European Commission requested EFSA to assess the acute exposure to glycerol (E 422) from slush ice drinks and de‐alcoholised wine. The acute exposure assessment was conducted on a single‑consumption‑event basis considering the reported use levels and analytical data of glycerol in slush ice drinks and the proposed maximum level of 50,000 ...
