Haha, I've been eating mussels since I was a bubba (not bubba the gangsta, but bubba the baby). Buy our New Zealand mussels
We have even more coastline than the US and ours are farmed in the most out of the way places. 100% fresh seawater.
Our expensive prawns are from Australia, flown in that morning, and even earlier that day swimming in the deep clear waters off NSW, so I'll only buy those ones from now on.
