eli5 why are mussels considered healthy even though they filter dirty water

417 views

Mussels and clams are considered to be very healthy. However their natural ‘job’ is cleaning seawater. Considering all the pollution in the oceans which is filtered by the mussels, how can they still be healthy and not be considered dirty or even toxic ?

They are filter feeders, not bottom feeders. Commercially harvested clams, mussels, and oysters come from very clean watersheds.

If there are toxins or heavy metals in the water, then they will take in and be able to get rid of those pollutants. I grew up in Cleveland and you don’t want to eat anything filtering that water.
