Dear List,
I will like to know where to find information about the
use of chloride dioxide in seafood...
I visit FDA page and only found that their use is allowed
during the washing of fresh produce (do not mention
anything about seafood washing)....
I have understood that it was not legal for washing
seafood (shrimp or fish), but I do not found anything that
say it is possible or not to use it... any reference or
web page will be appreciated...
Thanks in advance,
Lorena Noriega
