Parasites in these 200 old cans of salmon may spell good news for marine food webs
Parasites plague almost every creature on Earth, from ticks on dogs to lice on whales. But for marine ecologists, it’s hard to analyze the tiny creatures that lurk in big, elusive ones. Now, a new study uses a novel sample—commercially canned salmon—to do just that. The finding of more parasites in recent years may be good news for the health of salmon and other Pacific Ocean creatures, researchers say.
Although people “often think of [parasites] as being indicative of sickness … from an ecosystem perspective, they’re a sign of health,” says Jeb Byers, an ecologist at the University of Georgia who was n...

Safe and sustainable fish and seafood system and per- and poly-fluorinated substances occurrence: the role of PFAS toxicity in the assessment
Environ Sci Pollut Res Int. 2024 May 6. doi: 10.1007/s11356-024-33550-0. Online ahead of print.ABSTRACTFish and seafood are valuable sources of both nutrients and organic contaminants. The expansion of the analytical per- and polyfluoroalkyl substances (PFAS) panel with toxicological characterisation necessitates an update of PFAS intake assessment and management within the context of cumulative exposure. Benthic and demersal seafood, such as clams, squid, and cuttlefish, are more prone to contamination with C9-C14 perfluorocarboxylic acids, exhibiting the highest relative potency factors in terms of immunotoxicity, accord...

Still just a matter of taste? Sensorial appreciation of seafood is associated with more frequent and diverse consumption
Appetite. 2024 Apr 23:107369. doi: 10.1016/j.appet.2024.107369. Online ahead of print.ABSTRACTImproving health and sustainability outcomes in WEIRD (Western, Educated, Industrial, Rich, Democratic) nations necessitates a reduction in red meat consumption. Seafood is often overlooked in achieving this goal. However, simply consuming more of familiar fish species places high stress on production of these species. For this reason, diversification of seafood consumption is also critical. Here the motives for seafood consumption (frequency and diversity) are investigated across two studies by adapting the 4Ns survey to the seaf...

Sudden peak in tetrodotoxin in French oysters during the summer of 2021: Source investigation using microscopy, metabarcoding and droplet digital PCR
Toxicon. 2024 Apr 16;243:107721. doi: 10.1016/j.toxicon.2024.107721. Online ahead of print.ABSTRACTTetrodotoxin (TTX) is a potent neurotoxin causing human intoxications from contaminated seafood worldwide and is of emerging concern in Europe. Shellfish have been shown to contain varying TTX concentrations globally, with concentrations typically higher in Pacific oysters Crassostrea gigas in Europe. Despite many decades of research, the source of TTX remains unknown, with bacterial or algal origins having been suggested. The aim of this study was to identify potential source organisms causing TTX contamination in Pacific oy...
