ClearFood safety in the seaweed food supply chain : Inventory of production, consumption and chemical and physical hazards
This Dutch food safety report inventories the chemical and physical hazards — including microplastics — present in seaweed cultivated for human consumption. As the seaweed food market grows, understanding contamination risks including plastic particles is important for protecting consumer health.
Development of a framework and toolbox for measuring and evaluating ecosystem interactions of seaweed aquaculture
This Dutch-language study (mostly in Dutch) developed a framework and toolbox for measuring ecosystem integrity in seaweed cultivation areas off the Dutch coast, relevant to scaling up sustainable aquaculture. Healthy coastal ecosystems with minimal microplastic contamination are important for sustainable seaweed production.
Food safety hazards in the European seaweed chain
Researchers reviewed food safety hazards in the European seaweed supply chain, ranking 22 potential hazards based on available evidence. Arsenic, cadmium, iodine, and Salmonella were identified as major hazards, while micro- and nanoplastics were among the hazards where significant data gaps exist. The study recommends collecting more data on these under-researched hazards, noting that factors like seaweed type, cultivation location, and processing methods all influence contaminant levels.

Researchers developed a baseline environmental studies programme for seaweed cultivation in Faroese fjords, scoping potential impacts on the marine environment and recommending a monitoring programme to support sustainable and resilient aquaculture development in the Faroe Islands.
Developing the Use of Wool Rope within Aquaculture—A Systematic Review
This systematic review explores whether wool rope could replace plastic rope in seaweed aquaculture, reducing plastic pollution in marine environments. The research is directly relevant to microplastic concerns because conventional plastic ropes used in ocean farming gradually break down into microplastic particles that contaminate marine ecosystems and the seafood we eat.
Microplastics contamination in seaweed: impacts on human health and mitigation approaches
This review found that microplastics contaminate many types of edible seaweed, with fibers and fragments being the most common forms. Since seaweed is consumed worldwide, these microplastics can enter the human body and potentially cause oxidative damage, cell toxicity, and neurotoxicity. More research is needed to fully understand the health risks of eating microplastic-contaminated seaweed.
The Prevalence of Microplastics in Farmed Seaweed Kappaphycus Alvarezii in Panguil Bay, Philippines
Researchers investigated microplastic contamination in farmed seaweed from Panguil Bay, Philippines, and confirmed 1,298 microplastic particles across two farming sites. Fibers and filaments were the most common shapes, with rayon and polyester as the dominant polymer types, and washing seaweed before consumption reduced but did not eliminate microplastic content.
The Environmental Risks Associated With the Development of Seaweed Farming in Europe - Prioritizing Key Knowledge Gaps
This systematic review of environmental risks from European seaweed farming identified disease facilitation, population genetic alterations, and changes to the local physiochemical environment as the highest-priority concerns. While current small-scale operations are considered low risk, expanding to large-scale cultivation will require better understanding of scale-dependent environmental changes.
A review of microplastic pollution in aquaculture: Sources, effects, removal strategies and prospects
This review examines how microplastics contaminate fish farms through environmental inputs and aquaculture equipment, affecting water quality and the health of farmed seafood. Since contaminated aquaculture products are a direct pathway for microplastics to reach the human diet, reducing plastic pollution in fish farming is important for food safety.
Contribution of seaweed farming to the mitigation of greenhouse gas emissions and microplastics pollution
Researchers reviewed how seaweed farming can help fight two major environmental problems: seaweed absorbs CO2 from the atmosphere without competing for agricultural land, and seaweed-derived polymers can be used to make biodegradable plastics that break down without generating persistent microplastics. Scaling up seaweed-based bioplastics remains limited by production costs, but the potential environmental benefits make further research worthwhile.
Microplastics Content of Seaweeds in the Mariculture Potential Zone at The Southwest of Coastal Bawean Island
Researchers investigated microplastic contamination in seaweeds from Bawean Island, Indonesia, finding that even sheltered coastal waters contained microplastics in red, green, and brown seaweed species collected from mariculture potential zones.
Perspective Chapter: Health and Safety in Oyster Aquaculture
This paper is not directly about microplastics; it is a food safety review of oyster aquaculture covering chemical contaminants (heavy metals, antibiotics, pesticides), biological pathogens, and physical hazards that can threaten oyster safety and human health.
Establishment of Effective Callus Induction in the Economically Important Brown Seaweed Ecklonia cava
Not relevant to microplastics — this study describes tissue culture techniques for inducing callus growth in the edible brown seaweed Ecklonia cava to support sustainable aquaculture, with no connection to plastic pollution.
Microplastics in aquaculture systems: Occurrence, ecological threats and control strategies
This review summarizes how microplastics contaminate aquaculture systems through fishing gear, feed, and polluted water, and examines their effects on farmed aquatic species. Microplastics accumulate in farmed fish and shellfish, raising concerns about food safety for the millions of people who consume aquaculture products. The authors discuss removal strategies and call for better monitoring to protect both aquaculture sustainability and consumer health.
Seaweed as a sink for microplastic contamination: Uptake, identifications and food safety implications
This review examines how seaweed, a widely consumed food, absorbs and accumulates microplastics from ocean water. Research shows seaweed can account for up to 45.5% of total dietary microplastic intake in some regions, with particularly high levels in South Asia. The findings are concerning for human health because seaweed is eaten directly and is also increasingly used in health supplements and food additives.
Development of an analytical procedure to analyze microplastics in edible macroalgae using an enzymatic-oxidative digestion
Researchers developed a reliable enzymatic-oxidative digestion method to detect and quantify microplastics in edible macroalgae, addressing a gap in food safety monitoring by providing a standardized analytical procedure for assessing microplastic contamination in an increasingly popular food source.
Optimization of an analytical methodology to determine microplastic contamination in different seaweed groups (Phaeophyceae, Rhodophyta and Chlorophyta)
Seaweed growing in ocean waters can accumulate microplastics from its surrounding environment, making it a potential indicator species — but extracting microplastics from algae without destroying the plastic particles is technically difficult. This study optimized a two-step digestion process using cellulase enzymes followed by hydrogen peroxide for three species of seaweed, successfully recovering 8 of 12 tested polymer types with over 90% accuracy. The protocol gives researchers a reliable method for quantifying microplastics in seaweed, which matters both for environmental monitoring and for the growing seaweed food and supplement industry.
Threats of Microplastic Pollution on Aquaculture Activities in Indonesia
This review examined microplastic contamination in Indonesian aquaculture systems, including shrimp, fish, and seaweed farms. Microplastics were found in aquaculture environments and organisms throughout Indonesia, threatening both ecosystem health and seafood safety. The paper calls for better monitoring and management of plastic pollution in Indonesia's extensive aquaculture sector.
Microplastics in the commercial seaweed nori
Researchers quantified microplastic contamination in commercial nori (edible seaweed) at different stages of processing, finding that microplastics were present in both raw and processed products. The results suggest that nori can accumulate microplastics from its marine growing environment and retain them through processing into consumer products.
Occurrence and ecological impact of microplastics in aquaculture ecosystems
This review examines microplastic contamination specifically within aquaculture systems, which are an increasingly important source of protein for human diets worldwide. Researchers found that aquaculture environments accumulate microplastics from external sources like land-based waste and shipping, as well as from the plastic gear, equipment, and feed used in farming operations. The study raises concerns about food safety, as microplastics in farmed seafood represent a direct pathway of human exposure.
Microplastics in Coastal Aquaculture Systems: Development of Regulatory Frameworks, Practices and Mitigation Efforts in APEC Economies
This report reviewed the status of microplastic pollution in coastal aquaculture systems across Asia-Pacific economies and assessed existing regulatory frameworks and mitigation practices. Seafood consumers are directly exposed to microplastics through contaminated shellfish and fish, making aquaculture regulation an important food safety issue.
Development of Optimal Digesting Conditions for Microplastic Analysis in Dried Seaweed Gracilaria fisheri
Researchers compared enzymatic, oxidative, and combined digestion methods for extracting microplastics from dried seaweed, optimizing conditions for reliable identification and quantification. The combined method produced the best plastic recovery with the least damage to particles. Validated extraction methods for edible seaweeds are important because seaweed is increasingly consumed as food and could be a pathway for microplastic ingestion.
Plastisphere in Aquatic Food Production Systems and Seafood Safety
This chapter examines the plastisphere in aquaculture systems, reviewing how microbial communities on plastic surfaces in fish farming environments affect water quality, pathogen dynamics, and seafood safety, and discussing implications for aquaculture management.
Microplastics in seafood: Implications for food security, safety, and human health
This review examines how microplastics contaminate seafood -- from fish and shellfish to seaweed -- and what that means for food safety and human health. Marine organisms accumulate microplastics along with the harmful chemicals and antibiotic-resistant bacteria attached to them, creating multiple exposure risks when people eat seafood. With global seafood consumption rising sharply, the authors argue that microplastic contamination in the food supply deserves urgent attention from food safety regulators.
