(FMI) in accordance with the agency's proposed regulation, proposed 21 CFR 170.36 (62 FR 18938; April 17, 1997; Substances Generally Recognized as Safe (GRAS)). FDA received the notice on March 9, 2005 and designated it as GRAS Notice No. GRN 000166.

The subject of the notice is carbon monoxide (CO). The notice informs FDA of the view of FMI that CO is GRAS, through scientific procedures, for use in meat.

In accordance with proposed 21 CFR 170.36(f), a copy of the text of this letter, as well as a copy of the information in your notice that conforms to the information in proposed 21 CFR 170.36(c)(1), is available for public review and copying on the homepage of the Office of Food Additive Safety (on the Internet at http://www.cfsan.fda.gov/~lrd/foodadd.html).
