The subject came up with apparent interest at the recent Pacific Fisheries
Technologist meeting. Following is my understanding of the situation of CO use
in the U.S. I would appreciate any corrections.

CO continues to be used in tuna processing in Hawaii to enhance color
retention. There is interest among mainland processors as well.

Processors argue that CO is one of several compounds added during the normal
smoking process and therefore should not considered hazardous nor considered an
additive.

The stance the FDA is likely to take will be that CO treatment is an attempt to
mislead the consumer and will therefore be considererd economic adulteration
unless labeled accordingly. The FDA is currently working on a rapid method of
identifying products that have been CO treated.

I look forward to hearing the FDA response.
