Can I store live oysters on dry ice?

Trackback |     

I would strongly recommend not storing live oysters on or under dry ice. Dry ice is significantly colder than conventional ice and will very likely kill them (quite possibly by freezing them). In addition, as dry ice melts (sublimates) it turns into carbon dioxide gas, which may asphyxiate them.

Your concern about conventional ice melting into fresh water and drowning the oysters is valid, but the best solution is to set up a simple storage system where the shellfish are kept above any collecting water. Check out our blog post on how to store live shellfish for an example.
