Metabarcoding reveals marked seasonality and a distinctive winter assemblage of dinoflagellates at a coastal LTER site in the Gulf of Naples

Marine Ecology, Volume 44, Issue 3, June 2023., 2023
Abstract Dinoflagellates constitute an abundant and diversified component of marine plankton, mostly associated with stratified conditions typical of late spring through autumn in temperate regions. Yet, difficulties with the identification of many species limit the knowledge of their composition and seasonal succession.

Occurrence of marine biotoxins on Bulgarian Black Sea coastal waters in 2021 [PDF]

BioRisk, 2023
Marine biotoxins are produced by certain phytoplankton species and used to accumulate in filter-feeding marine organisms. The occurrence of marine biotoxins in all aquatic environments and latitudes is variable in time and space.

The efficacy and safety of high‐pressure processing of food

EFSA Journal, Volume 20, Issue 3, March 2022., 2022
Abstract High‐pressure processing (HPP) is a non‐thermal treatment in which, for microbial inactivation, foods are subjected to isostatic pressures (P) of 400–600 MPa with common holding times (t) from 1.5 to 6 min. The main factors that influence the efficacy (log10 reduction of vegetative microorganisms) of HPP when applied to foodstuffs are ...

Fatty acid esters of azaspiracids identified in mussels (Mytilus edulis) using liquid chromatography-high resolution mass spectrometry

Toxicon: X, 2020
Azaspiracids (AZAs) are lipophilic polyether toxins produced by Azadinium and Amphidoma species of marine microalgae. The main dinoflagellate precursors AZA1 and AZA2 are metabolized by shellfish to produce an array of AZA analogues.

Safety of oil from Schizochytrium sp. (strain ATCC 20889) for use in infant and follow‐on formula as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 20, Issue 1, January 2022., 2022
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of Schizochytrium sp. oil as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

Determination of Lipophilic Marine Biotoxins in Mussels Harvested from the Adriatic Sea by LC-MS/MS

Frontiers in Microbiology, 2018
Lipophilic marine biotoxins include okadaic acid, pectenotoxin, yessotoxin and azaspiracid groups. The consumption of contaminated molluscs can lead to acute food poisoning syndromes depending on the exposure level.

Solid phase extraction for removal of matrix effects in lipophilic marine toxin analysis by liquid chromatography-tandem mass spectrometry [PDF]

, 2009
The potential of solid phase extraction (SPE) clean-up has been assessed to reduce matrix effects (signal suppression or enhancement) in the liquid chromatography-tandem mass spectrometry (LC¿MS/MS) analysis of lipophilic marine toxins.

Diarrhetic Shellfish Toxins and Other Lipophilic Toxins of Human Health Concern in Washington State

Marine Drugs, 2013
The illness of three people in 2011 after their ingestion of mussels collected from Sequim Bay State Park, Washington State, USA, demonstrated the need to monitor diarrhetic shellfish toxins (DSTs) in Washington State for the protection of human health ...
