Hold off on the panic though; it's still too early for researchers to say what the effects of microplastic consumption are, although studies in animals suggest that they can certainly cause harm.

The pieces themselves seem relatively benign — they're just tiny bits of plastic, looking in large quantities like so much sand, created as larger plastic objects gradually degrade.
