ClearInfluence of Microplastics on the Growth and the Intestinal Microbiota Composition of Brine Shrimp
Researchers exposed brine shrimp to polyethylene and polystyrene microplastics and found that both types significantly reduced growth rates, with body length decreasing by 15-18%. The study also revealed that microplastic ingestion altered the gut microbiota composition, increasing microbial diversity and shifting the balance of key bacterial groups in the shrimp intestines.
Combined Vibrio and nanoplastics stress promotes nanoplastic accumulation while reducing bacterial lethality in shrimp
Researchers discovered that Vibrio bacteria act as carriers for nanoplastics in shrimp, ferrying the tiny particles through the gut wall and concentrating them in organs, but interestingly the nanoplastics also weakened the bacteria's ability to cause infection, showing that plastic-pathogen interactions in seafood are complex and two-directional.

The Effect of Microplastic Ingestion on Survival of the Grass Shrimp Palaemonetes pugio (Holthuis, 1949) Challenged with Vibrio campbellii
Grass shrimp (Palaemonetes pugio) that had ingested microplastics showed increased mortality when subsequently challenged with the marine pathogen Vibrio campbellii compared to shrimp that had not ingested plastics. This finding suggests that microplastic ingestion can compromise immune defenses in marine crustaceans, making them more vulnerable to bacterial infections.

Researchers conducted a risk assessment of microplastics in commercial table salt sold in Malaysia, finding that contaminated seawater used during sea salt production introduces microplastics into a widely consumed daily food ingredient with potential adverse health effects.
Microplastic Pollution in Table Salts from China
Researchers analyzed table salts produced in China and found microplastics contaminating samples from multiple salt types, suggesting that salt production processes and source water quality influence the extent of microplastic contamination in a common food ingredient.
Ingestion and bioaccumulation of polystyrene nanoplastics and their effects on the microalgal feeding of Artemia franciscana
Brine shrimp (Artemia franciscana) exposed to polystyrene nanoplastics ingested and bioaccumulated the particles, which also affected their feeding behavior on microalgae and caused changes in gut microbiota. These effects on a widely used aquaculture species raise concerns about nanoplastic contamination in marine food production.
Characterization of Microplastic-Associated Biofilm Development along a Freshwater-Estuarine Gradient
Researchers characterized biofilm bacterial communities on three types of microplastics incubated along a freshwater-estuarine gradient, finding that salinity and plastic type influenced microbial community composition and succession over a 31-day period.
From Sea Water to Salt Crystals: An Onsite Investigation of Microplastics in a Conventional Sea Salt Farming System

[Accumulation and Clearance of Polystyrene Microplastics in Brine Shrimp and the Responses of Microbiome and Metabolism].
Researchers exposed brine shrimp (Artemia salina) to polystyrene microplastics of different sizes and concentrations under varying nutritional conditions and analyzed microbiome and metabolic responses. Accumulation and clearance were concentration-dependent, while nutritional status modulated MP uptake; combined microbiome and metabolomics analysis revealed disruptions in microbial community composition and metabolic function.
Impact of microplastics on microbial diversity and pathogen distribution in aquaculture ecosystems: A seasonal analysis
Researchers studied bacteria growing on microplastics in fish farming waters and found that in summer, these plastic-attached communities became more connected and harbored several disease-causing species including Vibrio. Microplastics in aquaculture act as floating habitats for harmful bacteria, and seasonal warming makes this worse, raising concerns about seafood safety and the spread of infections to humans.
Impact of mariculture-derived microplastics on bacterial biofilm formation and their potential threat to mariculture: A case in situ study on the Sungo Bay, China
Scientists examined biofilm colonization on mariculture-derived microplastics (fishing nets, foams, floats) in Sanggou Bay, China over 21 days and found distinct microbial communities including potential fish pathogens and antibiotic resistance genes, raising concerns for mariculture safety.
Potential risks of microplastics combined with superbugs: Enrichment of antibiotic resistant bacteria on the surface of microplastics in mariculture system
Microplastics in a mariculture (sea farming) system were found to selectively enrich antibiotic-resistant bacteria on their surfaces compared to surrounding water, creating hotspots of antibiotic resistance in food production environments. This dual threat - microplastics acting as both pollutants and carriers of resistant pathogens - has significant implications for seafood safety.
