Background In a notice published in the Federal Register of April 18, 2005 (70 FR 20145), FDA announced that a food additive petition (FAP 5A4759) had been filed by Kareem I. Batarseh, P.O. Box 8, College Park, MD 20741–0008. The petition proposed to amend the food additive regulations in part 172, Food Additives Permitted for Direct Addition to Food for Human Consumption (21 CFR part 172), to provide for the safe use of an aqueous solution of silver nitrate and hydrogen peroxide as an antimicrobial agent in bottled drinking water at a level not to exceed 17 micrograms per kilogram (μg/ kg) of silver and 23 milligrams per kilogram (mg/kg) of hydrogen peroxide in the treated bottled water. II. Evaluation of Safety Under the general safety standard in section 409 of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 348), a food additive cannot be approved for a particular use unless a fair evaluation of the data available to E:\FR\FM\18MRR1.SGM 18MRR1 tjames on PRODPC61 with RULES Federal Register / Vol. 74, No. 51 / Wednesday, March 18, 2009 / Rules and Regulations FDA establishes that the additive is safe for that use. FDA’s food additive regulations (21 CFR 170.3(i)) define safe as ‘‘a reasonable certainty in the minds of competent scientists that the substance is not harmful under the intended conditions of use.’’ To establish with reasonable certainty that a food additive is not harmful under its intended conditions of use, FDA considers the estimated human dietary intake of the additive, the additive’s toxicological data, and other relevant information (such as published literature) available to the agency. FDA compares an individual’s estimated daily intake (EDI) of the additive to an acceptable intake level established by toxicological data. The EDI is determined by projections based on the amount of the additive proposed for use in particular foods and on data regarding the amount consumed from all sources of the additive. The agency commonly uses the EDI for the 90th percentile consumer of a food additive as a measure of high chronic dietary intake. FDA estimates the EDI of silver from the petitioned use in bottled water to be 26 micrograms per person per day (μg/ p/d) for the 90th percentile consumer aged 2 years or more (Ref. 1). Currently, silver is permitted as a component of an antimicrobial agent in water filters (the subject of effective food contact substance notification number 351 (Ref. 2)). The EDI from this filter use is 27 μg/ p/d for the 90th percentile consumer. The petitioner has proposed as a condition of safe use that the subject additive not be used in bottled water that has been or is intended to be filtered with a silver-containing water filter. Consequently, bottled water containing the subject additive will generally be consumed as a substitute for, rather than in addition to, bottled water that has been filtered with a silver-containing filter. Thus, the use of the subject additive in bottled water will not increase consumer exposure to silver. Because there is no increase in the intake of silver beyond a level that has already been established as safe, FDA has no concerns regarding the petitioned use of silver as a component of this additive. Regarding exposure to nitrate from use of the subject additive, FDA estimates that the maximum level of nitrate in bottled drinking water treated with the subject additive would result in a worst-case intake of 15 μg/p/d at the 90th percentile (Ref. 1), which is equivalent to 0.25 micrograms per kilogram body weight per day (μg/kgbw/d) in a 60 kg adult. FDA has no safety concerns because the intake of VerDate Nov<24>2008 13:31 Mar 17, 2009 Jkt 217001 nitrate in bottled drinking water treated with the subject additive is significantly lower than the chronic oral reference dose of 1,600 μg/kg-bw/d for nitrate that was established by the Environmental Protection Agency (Ref. 3). FDA also has no safety concerns regarding the use of hydrogen peroxide as a component of this additive as it will rapidly break down to water and oxygen after addition to the bottled water. Consequently, the dietary exposure to hydrogen peroxide from the petitioned use of the subject additive is essentially zero (Ref. 1). III. Conclusion FDA reviewed data in the petition and other available relevant material to evaluate the safety of the use of a mixture of silver nitrate and hydrogen peroxide as an antimicrobial agent in bottled water. Based on this information, the agency concludes that the proposed use of the additive is safe and the additive will achieve its intended technical effect as an antimicrobial agent under the proposed conditions of use. Therefore, the regulations in part 172 should be amended as set forth in this document. To ensure that food grade hydrogen peroxide is used in food, the additive must meet the specifications for hydrogen peroxide set forth in this regulation. FDA notes that bottled water must meet the quality standards for bottled water in § 165.110(b)(2) through (b)(5) (21 CFR 165.110(b)(2) through (b)(5)), including the limits specified for total silver and nitrate, unless the water bears a label statement of substandard quality, as provided for under § 165.110(c) (21 CFR 165.110(c)). Furthermore, bottled water containing a substance at a level considered injurious to health under section 402(a)(1) of the act (21 U.S.C. 342(a)(1)) is deemed adulterated, regardless of whether or not the water bears a label statement of substandard quality, § 165.110(d) (21 CFR 165.110(d)). IV. Public Disclosure In accordance with § 171.1(h) (21 CFR 171.1(h)), the petition and the documents that FDA considered and relied upon in reaching its decision to approve the petition will be made available for inspection at the Center for Food Safety and Applied Nutrition by appointment with the information contact person (see FOR FURTHER INFORMATION CONTACT). As provided in § 171.1(h), the agency will delete from the documents any materials that are not available for public disclosure PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 11477 before making the documents available for inspection. V. Environmental Impact The agency has previously considered the environmental effects of this rule as announced in the notice of filing for FAP 5A4759. No new information or comments have been received that would affect the agency’s previous determination that there is no significant impact on the human environment and that an environmental impact statement is not required. VI. Paperwork Reduction Act of 1995 This final rule contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required. VII. Section 301(ll) of the Federal Food, Drug, and Cosmetic Act FDA’s review of this petition was limited to section 409 of the act. This final rule is not a statement regarding compliance with other sections of the act. For example, the Food and Drug Administration Amendments Act of 2007, which was signed into law on September 27, 2007, amended the act to, among other things, add section 301(ll) (21 U.S.C. 301(ll)). Section 301(ll) of the act prohibits the introduction or delivery for introduction into interstate commerce of any food that contains a drug approved under section 505 of the act (21 U.S.C. 355), a biological product licensed under section 351 of the Public Health Service Act (42 U.S.C. 262), or a drug or biological product for which substantial clinical investigations have been instituted and their existence has been made public, unless one of the exceptions in 21 U.S.C. 301(ll)(1) to (ll)(4) applies. In our review of this petition, FDA did not consider whether section 301(ll) or any of its exemptions apply to food containing this additive. Accordingly, this final rule should not be construed to be a statement that a food containing this additive, if introduced or delivered for introduction into interstate commerce, would not violate section 301(ll). Furthermore, this language is included in all food additive final rules and therefore should not be construed to be a statement of the likelihood that section 301(ll) applies. VIII. Objections Any person who will be adversely affected by this regulation may file with the Division of Dockets Management (see ADDRESSES) written or electronic objections. Each objection shall be separately numbered, and each numbered objection shall specify with E:\FR\FM\18MRR1.SGM 18MRR1 11478 Federal Register / Vol. 74, No. 51 / Wednesday, March 18, 2009 / Rules and Regulations particularity the provisions of the regulation to which objection is made and the grounds for the objection.

SUPPLEMENTARY INFORMATION:

I. Background

    In a notice published in the Federal Register of April 18, 2005 (70 
FR 20145), FDA announced that a food additive petition (FAP 5A4759) had 
been filed by Kareem I. Batarseh, P.O. Box 8, College Park, MD 20741-
0008. The petition proposed to amend the food additive regulations in 
part 172, Food Additives Permitted for Direct Addition to Food for 
Human Consumption (21 CFR part 172), to provide for the safe use of an 
aqueous solution of silver nitrate and hydrogen peroxide as an 
antimicrobial agent in bottled drinking water at a level not to exceed 
17 micrograms per kilogram (microg/kg) of silver and 23 milligrams per 
kilogram (mg/kg) of hydrogen peroxide in the treated bottled water.

II. Evaluation of Safety

    Under the general safety standard in section 409 of the Federal 
Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 348), a food additive 
cannot be approved for a particular use unless a fair evaluation of the 
data available to

[[Page 11477]]

FDA establishes that the additive is safe for that use. FDA's food 
additive regulations (21 CFR 170.3(i)) define safe as ``a reasonable 
certainty in the minds of competent scientists that the substance is 
not harmful under the intended conditions of use.''
    To establish with reasonable certainty that a food additive is not 
harmful under its intended conditions of use, FDA considers the 
estimated human dietary intake of the additive, the additive's 
toxicological data, and other relevant information (such as published 
literature) available to the agency. FDA compares an individual's 
estimated daily intake (EDI) of the additive to an acceptable intake 
level established by toxicological data. The EDI is determined by 
projections based on the amount of the additive proposed for use in 
particular foods and on data regarding the amount consumed from all 
sources of the additive. The agency commonly uses the EDI for the 90th 
percentile consumer of a food additive as a measure of high chronic 
dietary intake.
    FDA estimates the EDI of silver from the petitioned use in bottled 
water to be 26 micrograms per person per day (microg/p/d) for the 90th 
percentile consumer aged 2 years or more (Ref. 1). Currently, silver is 
permitted as a component of an antimicrobial agent in water filters 
(the subject of effective food contact substance notification number 
351 (Ref. 2)). The EDI from this filter use is 27 microg/p/d for the 
90th percentile consumer. The petitioner has proposed as a condition of 
safe use that the subject additive not be used in bottled water that 
has been or is intended to be filtered with a silver-containing water 
filter. Consequently, bottled water containing the subject additive 
will generally be consumed as a substitute for, rather than in addition 
to, bottled water that has been filtered with a silver-containing 
filter. Thus, the use of the subject additive in bottled water will not 
increase consumer exposure to silver. Because there is no increase in 
the intake of silver beyond a level that has already been established 
as safe, FDA has no concerns regarding the petitioned use of silver as 
a component of this additive.
    Regarding exposure to nitrate from use of the subject additive, FDA 
estimates that the maximum level of nitrate in bottled drinking water 
treated with the subject additive would result in a worst-case intake 
of 15 microg/p/d at the 90th percentile (Ref. 1), which is equivalent 
to 0.25 micrograms per kilogram body weight per day (microg/kg-bw/d) in 
a 60 kg adult. FDA has no safety concerns because the intake of nitrate 
in bottled drinking water treated with the subject additive is 
significantly lower than the chronic oral reference dose of 1,600 
microg/kg-bw/d for nitrate that was established by the Environmental 
Protection Agency (Ref. 3).
    FDA also has no safety concerns regarding the use of hydrogen 
peroxide as a component of this additive as it will rapidly break down 
to water and oxygen after addition to the bottled water. Consequently, 
the dietary exposure to hydrogen peroxide from the petitioned use of 
the subject additive is essentially zero (Ref. 1).

III. Conclusion

    FDA reviewed data in the petition and other available relevant 
material to evaluate the safety of the use of a mixture of silver 
nitrate and hydrogen peroxide as an antimicrobial agent in bottled 
water. Based on this information, the agency concludes that the 
proposed use of the additive is safe and the additive will achieve its 
intended technical effect as an antimicrobial agent under the proposed 
conditions of use. Therefore, the regulations in part 172 should be 
amended as set forth in this document.
    To ensure that food grade hydrogen peroxide is used in food, the 
additive must meet the specifications for hydrogen peroxide set forth 
in this regulation.
    FDA notes that bottled water must meet the quality standards for 
bottled water in Sec.  165.110(b)(2) through (b)(5) (21 CFR 
165.110(b)(2) through (b)(5)), including the limits specified for total 
silver and nitrate, unless the water bears a label statement of 
substandard quality, as provided for under Sec.  165.110(c) (21 CFR 
165.110(c)). Furthermore, bottled water containing a substance at a 
level considered injurious to health under section 402(a)(1) of the act 
(21 U.S.C. 342(a)(1)) is deemed adulterated, regardless of whether or 
not the water bears a label statement of substandard quality, Sec.  
165.110(d) (21 CFR 165.110(d)).

IV. Public Disclosure

    In accordance with Sec.  171.1(h) (21 CFR 171.1(h)), the petition 
and the documents that FDA considered and relied upon in reaching its 
decision to approve the petition will be made available for inspection 
at the Center for Food Safety and Applied Nutrition by appointment with 
the information contact person (see FOR FURTHER INFORMATION CONTACT). 
As provided in Sec.  171.1(h), the agency will delete from the 
documents any materials that are not available for public disclosure 
before making the documents available for inspection.

V. Environmental Impact

    The agency has previously considered the environmental effects of 
this rule as announced in the notice of filing for FAP 5A4759. No new 
information or comments have been received that would affect the 
agency's previous determination that there is no significant impact on 
the human environment and that an environmental impact statement is not 
required.

VI. Paperwork Reduction Act of 1995

    This final rule contains no collection of information. Therefore, 
clearance by the Office of Management and Budget under the Paperwork 
Reduction Act of 1995 is not required.

VII. Section 301(ll) of the Federal Food, Drug, and Cosmetic Act

    FDA's review of this petition was limited to section 409 of the 
act. This final rule is not a statement regarding compliance with other 
sections of the act. For example, the Food and Drug Administration 
Amendments Act of 2007, which was signed into law on September 27, 
2007, amended the act to, among other things, add section 301(ll) (21 
U.S.C. 301(ll)). Section 301(ll) of the act prohibits the introduction 
or delivery for introduction into interstate commerce of any food that 
contains a drug approved under section 505 of the act (21 U.S.C. 355), 
a biological product licensed under section 351 of the Public Health 
Service Act (42 U.S.C. 262), or a drug or biological product for which 
substantial clinical investigations have been instituted and their 
existence has been made public, unless one of the exceptions in 21 
U.S.C. 301(ll)(1) to (ll)(4) applies. In our review of this petition, 
FDA did not consider whether section 301(ll) or any of its exemptions 
apply to food containing this additive. Accordingly, this final rule 
should not be construed to be a statement that a food containing this 
additive, if introduced or delivered for introduction into interstate 
commerce, would not violate section 301(ll). Furthermore, this language 
is included in all food additive final rules and therefore should not 
be construed to be a statement of the likelihood that section 301(ll) 
applies.

VIII. Objections

    Any person who will be adversely affected by this regulation may 
file with the Division of Dockets Management (see ADDRESSES) written or 
electronic objections. Each objection shall be separately numbered, and 
each numbered objection shall specify with

[[Page 11478]]

particularity the provisions of the regulation to which objection is 
made and the grounds for the objection. Each numbered objection on 
which a hearing is requested shall specifically so state. Failure to 
request a hearing for any particular objection shall constitute a 
waiver of the right to a hearing on that objection. Each numbered 
objection for which a hearing is requested shall include a detailed 
description and analysis of the specific factual information intended 
to be presented in support of the objection in the event that a hearing 
is held. Failure to include such a description and analysis for any 
particular objection shall constitute a waiver of the right to a 
hearing on the objection. Three copies of all documents are to be 
submitted and are to be identified with the docket number found in 
brackets in the heading of this document. Any objections received in 
response to the regulation may be seen in the Division of Dockets 
Management between 9 a.m. and 4 p.m., Monday through Friday.
