An Australian study revealed that 100 grams of sardines contain up to 30 micrograms of plastic. Other seafood such as squid, oysters, and the now-famous blue crabs also contain microplastic levels that may be harmful to health if consumed regularly. Let’s take a closer look at which fish are best avoided — and why.
Microplastics: A Growing Threat to Our Health
We’ve often discussed how microplastics — tiny fragments of plastic less than 5 mm in size — enter our bodies through the food we eat, the water we drink, and even the air we breathe, causing damage that is still not fully understood.
According to a WWF analysis, the average person ingests around 5 grams of plastic every week — roughly the weight of a credit card. Alarmingly, shellfish account for around 10% of that intake.
A recent study by the Quex Institute (a collaboration between the Universities of Exeter and Queensland) confirmed the presence of microplastics in nearly every type of seafood tested.
