Yes. A 2020 study of Norway lobsters (Nephrops norvegicus) collected near Sardinia found that some ingested plastic particles were mechanically broken into smaller pieces as they passed through the animals’ stomachs. The finding points to one possible way biological digestion can add smaller plastic fragments to the deep-sea environment; it does not show how many are released or how important this process is across the ecosystem.
Can lobsters break plastic into smaller pieces?
In the study, larger plastic particles were retained in the stomach, and some passed through the lobster’s gastric mill. This set of hard structures grinds food; the researchers’ account indicates that it also fragmented some plastic into smaller particles that then moved into the intestines. The finding concerns Norway lobster, also called langoustine or scampi, not every animal known as a lobster.
A review published in 2023 describes field evidence consistent with this mechanism: particle counts increased and particle size decreased along the Norway lobster’s gastrointestinal tract. It identifies the gastric mill as the likely means of physical fragmentation and discusses similar observations in other animals, including shore crabs and Antarctic krill. That broader evidence supports the plausibility of animal-driven fragmentation, but it does not establish how much plastic Norway lobsters release.
What are secondary microplastics?
The U.S. Environmental Protection Agency defines microplastics as plastic particles smaller than 5 mm. Primary microplastics are made at that small size; secondary microplastics form when larger plastic breaks apart. As the EPA puts it, “Secondary microplastics are formed as a result of the fragmentation or break up of larger plastic pieces.”

In this case, the lobster does not create plastic from nothing: it may make smaller fragments from plastic it has already ingested. Environmental weathering can also break larger plastic down. The Norway lobster study supports a mechanical, biological route, but does not show that digestion is a major source of marine microplastics compared with other processes.
Could lobster digestion add plastic fragments to the deep sea?
The 2020 study authors suggested that smaller fragments could be expelled by living animals and could become more available to smaller deep-sea organisms. Those are possible environmental consequences, not measured outcomes: the report does not quantify how many fragments a lobster releases or demonstrate that other organisms consume them. The American Chemical Society, reporting the study, described the authors’ interpretation as a possible significant pathway of plastic degradation in the deep sea, not as a measured ecosystem-wide contribution.

A separate 2021 study of Norway lobsters considered where plastic ingestion occurred, rather than testing the digestive grinding mechanism. In its model, proximity to seafloor macroplastic hotspots was significantly related to ingestion, while the presence of a local hotspot itself was not significantly related. This finding does not replicate or quantify the 2020 digestion result.

No conclusion about consumer health follows from this digestion study. It examined how ingested particles may change inside Norway lobsters; it did not assess whether fragments reach people through seafood or whether they cause illness.
Food Standards Australia New Zealand (FSANZ), whose guidance was updated on 25 February 2025, says evidence on exposure and health risks is evolving. It states that absorption of intact plastic particles from the gut is likely to be very limited and that available evidence suggests plastic contamination of the food chain is unlikely to cause immediate consumer health risks. This is a general assessment of food-chain contamination, not a lobster-specific guarantee.

What the finding establishes—and what it does not
- Established: Some plastic particles in the studied Norway lobsters were fragmented along the digestive tract, with the gastric mill identified as the likely physical mechanism.
- Not established: A release rate, the number of fragments entering the environment, the pathway’s share of total marine microplastic production, or downstream harm to deep-sea food webs.
- Not a health finding: The study does not show that lobster-generated fragments reach seafood consumers or cause disease.
