What if it says this?


Would that be the same as using Sodium Tripolyphosphate? or would it be safe?

Edit... Research says:

Carbon monoxide-treated fish is safe to eat, but the treatment does deprive consumers of visual cues about the freshness and handling of the seafood they’re buying. And that could be especially important when the fish comes from China, where aquaculture is poorly regulated.

While it is illegal to sell fish treated with carbon monoxide in the European Union, it is permissible in the United States. Consumer groups and producers of genuinely fresh tilapia filets, generally farmed in Latin America, object to the practice, saying it is deceptive.
It is unclear how much of what appears to be fresh tilapia on American fish counters was previously frozen. Chinese fish farms say they treat frozen fish with carbon monoxide because American importers request it, although there is a move to ban the practice.


Probably best to not feed it to them...
