Microplastics in Fish and Shellfish – A Threat to Seafood Safety?

Seafood allergies: Fish and shellfish

Paralytic shellfish poisoning: seafood safety and human health perspectives.

Paralytic shellfish poisoning (PSP) is the foodborne illness associated with the consumption of seafood products contaminated with the neurotoxins known collectively as saxitoxins (STXs). This family of neurotoxins binds to voltage-gated sodium channels, thereby attenuating action potentials by preventing the passage of sodium ions across the membrane. Symptoms include tingling, numbness, heada...

Microplastics in seafood: Benchmark protocol for their extraction and characterization.

Pollution of the oceans by microplastics (<5 mm) represents a major environmental problem. To date, a limited number of studies have investigated the level of contamination of marine organisms collected in situ. For extraction and characterization of microplastics in biological samples, the crucial step is the identification of solvent(s) or chemical(s) that efficiently dissolve organic matter ...

Ocean acidification increases cadmium accumulation in marine bivalves: a potential threat to seafood safety

To date, the effects of ocean acidification on toxic metals accumulation and the underlying molecular mechanism remains unknown in marine bivalve species. In the present study, the effects of the realistic future ocean pCO2 levels on the cadmium (Cd) accumulation in the gills, mantle and adductor muscles of three bivalve species, Mytilus edulis, Tegillarca granosa, and Meretrix meretrix, were i...

Traditional jute (Corchorus spp.) retting process: A significant threat to fish health and fish biodiversity in Chandpur District, Bangladesh

The study was conducted to assess the impact of traditional jute retting process on the fish health and fish biodiversity in the six upazilas of Chandpur district, Bangladesh. Data were collected from respondents through face to face interviews and focus group discussions. All of the jute farmers in the study area used traditional water retting methods to extract fibres and these methods were e...
