A new peer-reviewed paper titled “Examining Misconceptions about Plastic-Particle Exposure from Ingestion of Seafood and Risk to Human Health” (Henry et al.) has stirred interest across the scientific, regulatory, and seafood communities. While microplastic contamination remains a concern, this work argues that seafood has been unfairly singled out – and that risk perceptions may be out of proportion with actual exposure. Below is a digest of the key findings and what they mean for the seafood sector.

Key Insights from the Study

1. Seafood is overrepresented in microplastic discourse

Henry et al. found that more than 70 % of scientific and media coverage on microplastics in foods focuses on seafood. This focus, they argue, reflects historical assumptions and sampling convenience rather than a clear scientific justification. (Vlaams Instituut voor de Zee)

Because seafood was among the earliest food categories studied for microplastics, its reputation as a “high-risk” vector has become entrenched – even when emerging data suggest otherwise. (Vlaams Instituut voor de Zee)

2. Relative exposure from seafood is modest

According to their synthesis, consuming seafood (e.g. mussels, oysters, finfish like salmon or cod) may contribute 1 to 10 microplastic particles per person per day. (Phys.org)

By contrast:

• Bottled water might contribute 10 to 100 particles/day
• Indoor air and household dust are estimated to deliver 100 to 1,000 particles/day (Phys.org)

Thus, while microplastics are ubiquitous, the dietary load from seafood is not out of scale compared to other vectors. (Vlaams Instituut voor de Zee)

3. Limited evidence of health harm at current exposure levels

Henry et al. emphasize that, to date, there is minimal – or no well-established evidence that the microplastic particles ingested through food pose significant health hazards in humans. (Phys.org)

They note that most particles are likely to pass through the gastrointestinal tract and be excreted, rather than accumulate or cause toxicity. (thefishingdaily.com)

While chemical additives or pollutants associated with microplastics may raise theoretical concerns, the study finds that the amounts likely to be transferred under realistic ingestion scenarios are orders of magnitude below levels of toxicological concern. (Vlaams Instituut voor de Zee)

4. The messaging around seafood matters

One of the strongest messages from the authors is that sensational media coverage or unbalanced framing can distort public perception, potentially discouraging seafood consumption. They argue that better communication is needed – placing seafood in context relative to other exposure routes, being transparent about uncertainties, and emphasizing that seafood still provides significant nutritional benefits.

What This Means for the Seafood Industry

Reframe the narrative

The industry is well positioned to counter oversimplified narratives that portray seafood as uniquely or excessively contaminated. Sharing data like exposure ranges, comparisons with non-seafood sources, and the current lack of conclusive harm can help re-center the debate.

Emphasize benefits, not just risk

Seafood offers well-documented health benefits – omega-3s, protein, trace minerals – that are lost when consumers reduce intake due to fear of microplastic ingestion. The study’s findings provide a more balanced basis for marketing and public education.

Support transparency and research

Gaps remain: the study highlights uncertainties in uptake, tissue accumulation, long-term effects, and standardized methods for detecting microplastics in seafood. Companies and industry associations can support further research, harmonization of analytical methods, and communication of findings to stakeholders.

Engage with regulators and media

Regulatory bodies, consumer advocacy groups, and journalists often shape public perception of food safety. The seafood industry should proactively engage in those discussions, offering informed perspectives grounded in the evolving science.

A Balanced View Forward

Henry et al. do not dismiss microplastics as a concern. Rather, they call for nuance, rigor, and proportionate risk framing. As research evolves, monitoring, quality controls, and methodological consistency will be critical. Meanwhile, the seafood sector has an opportunity – and responsibility – to help ensure consumers are neither unduly alarmed nor misled.
