Re: GRAS Notice No. GRN 000235

Dear Mr. Deeter:

The Food and Drug Administration (FDA) is responding to the notice, dated September 27, 2007, that Ventria Bioscience submitted 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); the GRAS proposal). FDA received the notice on October 02, 2007, filed it on October 19, 2007, and designated it as GRAS Notice No. GRN 000235.

The subject of the notice is human lactoferrin purified from rice (hLF-r). The notice informs FDA of the view of Ventria Bioscience that hLF-r is GRAS, through scientific procedures, for use as an ingredient in oral rehydration solutions that are medical foods intended for short-term consumption by children less than five years of age at levels up to one gram per liter of solution.

In a letter dated March 5, 2010, you withdrew your notice and asked that FDA cease to evaluate your notice. Given your request, we ceased to evaluate your GRAS notice, effective March 12, 2010, the date that we received your letter.

In accordance with proposed 21 CFR 170.36(f), a copy of the text of this letter responding to GRN 000235, as well as a copy of the information in this notice that conforms to the information in the GRAS exemption claim (proposed 21 CFR 170.36(c)(1)), is available for public review and copying via the FDA home page at To view or obtain an electronic copy of the text of the letter, follow the hyperlinks from the “Food” topic to the “Food Ingredients and Packaging” section to the “Generally Recognized as Safe (GRAS)” page where the GRAS Inventory is listed.
