We’re not getting a side order of plastic with our shrimp after all
Most microplastics pass through seafood and don’t reach our dinner plates, scientists have found
Microplastics may not make their way on to our plates through seafood, as studies on sea bass and shrimp have concluded that most of the tiny particles completely pass through them.
Microplastics, defined as anything less than 5mm in diameter, have been found across the globe. They spread through waterways and on the air from plastic rubbish, car tyres and fibres. But researchers in Germany have found almost none in the muscle tissue of sea bass, the part that makes up a fillet, despite a steady diet.
The fish were fed an average of 163 million bits of microplastic measuring one to five micrometres (thousandths of a millimetre) each over four months – much more than they are normally exposed to. The scientists tracked the microplastics by dyeing them, and found only one or two particles for every five grams of muscle tissue...
