# Salts of volatile fatty acids.
**AGENCY:**
Food and Drug Administration, HHS.
**ACTION:**
Final rule; technical amendment.
**SUMMARY:**
The Food and Drug Administration (FDA) is amending the animal food additive regulations to correct the specifications for two food additives used in cattle feed. Incorrect symbols describing permitted levels of heavy metals such as lead and arsenic are being corrected with text to reflect the maximum permitted levels of these two impurities in these food additives. This action is being taken to improve the accuracy of the agency's regulations.
**DATES:**
This rule is effective March 18, 2005.

**SUPPLEMENTARY INFORMATION:**
FDA has found that part 573 (21 CFR part 573) of the Code of Federal Regulations does not accurately reflect the approved specifications for two food additives used in cattle feed, poly(2-vinylpyridine-co-styrene) and salts of volatile fatty acids. The greater than symbols in the tables describing the permitted levels of heavy metals such as lead and arsenic were incorrect. FDA is amending the regulations in §§ 573.870 and 573.914 to correctly reflect the maximum permitted levels of these two impurities in these food additives. This action is being taken to improve the accuracy of the agency's regulations.
Publication of this document constitutes final action on these changes under the Administrative Procedure Act (5 U.S.C. 553). Notice and public procedure are unnecessary because FDA is merely correcting nonsubstantive errors.
