A New Cytotoxicity Assay for Brevetoxins Using Fluorescence Microscopy

Marine Drugs, 2014
Brevetoxins are a family of ladder-framed polyether toxins produced during blooms of the marine dinoflagellate, Karenia brevis. Consumption of shellfish or finfish exposed to brevetoxins can lead to the development of neurotoxic shellfish poisoning.

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 ...

Monitoring the 2007 Florida east coast Karenia brevis (Dinophyceae) red tide and neurotoxic shellfish poisoning (NSP) event

ALGAE, 2015
have been reported in this area. This extensive red tide influenced commercial and recreational shellfish harvesting activities along Florida’s east coast. Fourteen shellfish harvesting areas (SHAs) were monitored weekly during this event and 10 SHAs were closed for an average of 53 days due to this red tide.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Limnological Differences in a Two-Basin Lake Help to Explain the Occurrence of Anatoxin-a, Paralytic Shellfish Poisoning Toxins, and Microcystins

Toxins, 2020
Chautauqua Lake, New York, is a two-basin lake with a deeper, cooler, and less nutrient-rich Northern Basin, and a warmer, shallower, nutrient-replete Southern Basin.

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 ...

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...

Diatoms–copepods: An evolutionary arms race

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are arguably the most abundant group of metazoans in the ocean, typically accounting for ~ 80% of zooplankton biomass.

Paralytic shellfish toxin content is related to genomic sxtA4 copy number in Alexandrium minutum strains

Frontiers in Microbiology, 2015
Dinoflagellates are microscopic aquatic eukaryotes with huge genomes and an unusual cell regulation. For example, most genes are present in numerous copies and all copies seem to be obligatorily transcribed.

Predicting Karenia brevis Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Nearly annually, blooms of the dinoflagellate Karenia brevis form along the southwest Florida coast leading to a variety of negative impacts, including respiratory irritation (RI) in humans. To limit these impacts, NOAA's National Centers for Coastal Ocean Science (NCCOS) developed a RI model to provide beach‐goers with a category‐based ...
