Eight million tonnes of waste plastic ends up in the sea each year. Fish eat it – and then we do. How bad is it for us?

It’s enough to make you cry over your moules frites. Scientists at Ghent University in Belgium recently calculated that shellfish lovers are eating up to 11,000 plastic fragments in their seafood each year. We absorb fewer than 1%, but they will still accumulate in the body over time. The findings affect all Europeans, but, as the most voracious consumers of mussels, the Belgians were deemed to be most exposed. Britons should sympathise – last August, the results of a study by Plymouth University caused a stir when it was reported that plastic was found in a third of UK-caught fish, including cod, haddock, mackerel and shellfish. Now, UK supermarkets are being lobbied to create plastic-free aisles by the campaign group Plastic Oceans Foundation, whose feature-length documentary, A Plastic Ocean, was released in Britain this week.

We are finally paying attention to the pollution that has plagued our seas for years – the government is considering a refundable deposit on plastic bottles, and pharmaceutical company Johnson & Johnson recently switched from plastic to paper stems on its cotton buds. Evidently, there’s nothing like serving plastic up on a dinner plate to focus the mind.
