ClearMicroplastics aggravate the bioaccumulation and corresponding food safety risk of antibiotics in edible bivalves by constraining detoxification-related processes
Researchers found that microplastics increased the accumulation of antibiotics in three commercially important species of edible shellfish. The microplastics interfered with the animals' natural detoxification processes, making it harder for them to clear antibiotic residues from their tissues. The study raises food safety concerns, suggesting that microplastic-contaminated coastal waters could lead to higher antibiotic levels in the seafood people consume.
An Overview of Antibiotics as Emerging Contaminants: Occurrence in Bivalves as Biomonitoring Organisms
Researchers reviewed the occurrence of antibiotic residues in bivalve mollusks used as biomonitoring organisms across European, American, and Asian coastlines. They found that macrolides, sulfonamides, and quinolones were the most frequently detected antibiotic classes, though the health risk from consuming contaminated bivalves was generally assessed as negligible. The study emphasizes the importance of continued monitoring to prevent the development of antimicrobial resistance from environmental antibiotic contamination.

Impact of microplastics pollution on ciprofloxacin bioaccumulation in the edible mussel (Perna viridis): Implications for human gut health risks
Researchers studied how microplastics affect the accumulation of the antibiotic ciprofloxacin in edible green mussels from a mariculture farm. They found that microplastics altered the way mussels absorbed and retained the antibiotic, with implications for human gut health when contaminated seafood is consumed. The study highlights the compounding food safety risks when multiple pollutants interact in aquaculture environments.
The problem of contamination of aquatic ecosystems with antibiotics (a review)
This review examines the contamination of aquatic ecosystems by antibiotics, synthesizing global data on risks associated with antibiotic presence in ocean and freshwater environments, including effects on aquatic organisms and the promotion of antibiotic resistance. The authors assess quantitative and qualitative contamination using bivalves as bioindicators and evaluate the spread of resistance genes through aquatic biocenoses.
Towards Risk Assessments of Microplastics in Bivalve Mollusks Globally
Researchers compiled data from 22 countries to assess the risk of microplastic contamination in bivalve mollusks such as mussels and oysters. While most countries showed relatively low pollution levels, the chemical composition of the microplastics found in bivalves varied widely, with some polymers posing greater health concerns than others. The study estimates that regular consumption of contaminated bivalves could represent a meaningful pathway for human microplastic exposure.

This review examines microplastic contamination in coastal and marine environments, focusing on bivalves as sentinel organisms due to their filter-feeding behavior and widespread use as human food, synthesizing evidence on physiological damage across aquatic species and ecological risks from plastic particle transfer through food chains.
Source and risk assessment of heavy metals and microplastics in bivalves and coastal sediments of the Northern Persian Gulf, Hormogzan Province
Researchers assessed heavy metal contamination and microplastic distribution in coastal sediments and edible bivalves from the northern Persian Gulf in Hormozgan Province. They found varying levels of both pollutant types across sampling sites, with proximity to industrial and urban areas correlating with higher contamination. The study provides a risk assessment indicating that combined exposure to heavy metals and microplastics through seafood consumption in the region warrants monitoring.
Understanding the risks of co-exposures in a changing world: A case study of dual monitoring of the biotoxin domoic acid and Vibrio spp. in Pacific oyster
This paper is not relevant to microplastics research — it examines the co-occurrence of the harmful algal toxin domoic acid and Vibrio bacteria in Pacific oysters in California, focusing on food safety risks from biological rather than plastic contaminants.

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.
Impact of Microplastic in Mexican Coastal Areas Using Mussels ( Mytilus spp.) as Biomonitors

The impact of microplastics on bivalve mollusks: A bibliometric and scientific review
This review examines how microplastics affect bivalve shellfish like mussels, oysters, and clams, which are important both ecologically and as human food sources. Microplastics disrupt bivalve feeding, growth, reproduction, and immune function, and can also carry other toxic pollutants into their tissues. Since bivalves filter large volumes of water and are often eaten whole by humans, they represent a direct pathway for microplastic transfer from the ocean to our bodies.
