7 CFR Part 58

[DA-93-03]

Grading and Inspection, General Specifications for Approved
Plants and Standards for Grades of Dairy Products; United States
Standards for Grades of Nonfat Dry Milk (Spray Process)

AGENCY: Agricultural Marketing Service, USDA.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This document proposes to revise the United States Standards
for Grades of Nonfat Dry Milk (Spray Process). The proposed changes
would reduce existing bacterial standard plate count maximums and
incorporate a coliform requirement to reflect the ability of the U.S.
dairy industry to produce high-quality nonfat dry milk. The reduction
in the maximum standard plate count is made possible through improved
raw milk quality and enhanced processing and sanitation techniques. The
inclusion of a maximum coliform count adds to the assurance that post-
pasteurization contamination has not occurred. This proposal was
developed in cooperation with the American Dairy Products Institute and
other trade associations.

DATES: Comments should be filed by May 5, 1995.

ADDRESSES: Comments should be sent to: Director, Dairy Division,
Agricultural Marketing Service, U.S. Department of Agriculture, Room
2968-S, P.O. Box 96456, Washington, DC 20090-6456. They will be
available for public inspection at the Dairy Division in Room 2750-S
during regular business hours.

FOR FURTHER INFORMATION CONTACT: Roland S. Golden, Dairy Products
Marketing Specialist, Dairy Standardization Branch, USDA/AMS/Dairy
Division, Room 2750-S, P.O. Box 96456, Washington, DC 20090-6456, (202)
720-7473.

SUPPLEMENTARY INFORMATION: This proposed rule has been reviewed under
Executive Order 12778, Civil Justice Reform. This action is not
intended to have retroactive effect. This rule would not preempt any
State or local laws, regulations, or policies, unless they present an
irreconcilable conflict with this rule. There are no administrative
procedures which must be exhausted prior to any judicial challenge to
the provisions of this rule.
The proposed rule also has been reviewed in accordance with the
Regulatory Flexibility Act, 5 U.S.C. 601 et seq. The Administrator,
Agricultural Marketing Service, has determined that the proposed rule,
if promulgated, would not have a significant economic impact on a
substantial number of small entities because use of the standards is
voluntary and the revisions would not increase costs to those utilizing
the standards.
The Department is issuing this rule in conformance with Executive
Order 12866.
To provide quality grade standards that reflect the ability of the
U.S. dairy industry to produce high-quality nonfat dry milk, USDA is
proposing the following changes in the U.S. Standards for Grades of
Nonfat Dry Milk (Spray Process). [[Page 12157]]

1. Expand the U.S. Grade Standards To Include a Maximum Coliform Count
in USDA-Graded Product

Coliform bacteria, abundantly present in the environment, are
destroyed by pasteurization. Post-pasteurization contamination has
occurred when coliform bacteria are present in nonfat dry milk. The
addition of a coliform requirement into the U.S. grade standard
increases the assurance that USDA graded nonfat dry milk is produced
and packaged in a sanitary manner.

2. Reduce the Standard Plate Count Requirements

Enumeration of bacteria by the standard plate count method has been
a criterium used in the determination of U.S. grade for many years.
Improvements in the sanitary production of nonfat dry milk have
resulted in a gradual reduction in the number of bacteria present in
the product. The proposal would reduce the allowable bacteria from
50,000 to 40,000 per gram for U.S. Extra Grade and from 100,000 to
75,000 per gram for U.S. Standard Grade. These proposed changes
accurately reflect the ability of the U.S. dairy industry to produce
high-quality nonfat dry milk and enhance the image of U.S. products on
the world market.

3. Update the Terminology and Format of the Standards

The current U.S. Standards for Grades of Nonfat Dry Milk (Spray
Process) were last revised in 1984. Since that time, changes in
terminology and formatting of standards have taken place. The proposal
would update the standards to provide consistency among the various
U.S. grade standards.
USDA grade standards are voluntary standards that are developed
pursuant to the Agricultural Marketing Act of 1946 (7 U.S.C. 1621 et
seq.) to facilitate the marketing process. Manufacturers of dairy
products are free to choose whether or not to use these grade
standards. USDA grade standards for dairy products have been developed
to identify the degree of quality in the various products. Quality in
general refers to usefulness, desirability, and value of the product--
its marketability as a commodity. When nonfat dry milk is officially
graded, the USDA regulations and standards governing the grading of
manufactured or processed dairy products are used. These regulations
also require a charge for the grading service provided by USDA. The
Agency believes this proposal would accurately identify quality
characteristics in nonfat dry milk.
Corollary changes are also proposed for the General Specifications
for Dairy Plants Approved for USDA Inspection and Grading Service, to
conform the definition of nonfat dry milk set forth therein with the
proposed revision of the United States Standards for Grades of Nonfat
Dry Milk (Spray Process).

List of Subjects in 7 CFR Part 58

Sec. 58.2538 Basis for obtaining heat treatment classification.

Heat treatment classification is not a U.S. grade requirement
except in cases when the higher solubility index specified for U.S.
High-heat product is permitted. In all other instances, product
submitted for USDA grading may be analyzed for heat treatment
classification upon request and the results shown on the grading
certificate. Heat treatment classification will be made available only
upon a product graded by USDA.

Sec. 58.2339 Nomenclature of U.S. Heat Treatment Classification.

The nomenclature of U.S. Heat Treatment Classification is as
follows:
(a) U.S. High-heat.
(b) U.S. Medium-heat.
(c) U.S. Low-heat.

Sec. 58.2540 Basis for determination of U.S. Heat Treatment
Classification.

The whey protein nitrogen test shall be used in determining the
heat treatment classification as follows:
(a) U.S. High-heat. The finished product shall not exceed 1.50 mg.
undenatured whey protein nitrogen per gram of nonfat dry milk.
(b) U.S. Medium-heat. The finished product shall exceed 1.50 mg.
undenatured whey protein nitrogen per gram of nonfat dry milk and shall
be less than 6.00 mg. undenatured whey protein nitrogen per gram of
nonfat dry milk.
(c) U.S. Low-heat. The finished product shall be not less than 6.00
mg. undenatured whey protein nitrogen per gram of nonfat dry milk.

Sec. 58.2541 Test method; whey protein nitrogen.

The whey protein nitrogen test shall be performed in accordance
with DA Instruction 918-RL, ``Instruction for Resident Grading Quality
Control Service Programs and Laboratory Analysis,'' Dairy Grading
Branch, Dairy Division, Agricultural Marketing Service, U. S.
Department of Agriculture, Washington, DC 20090-6456, or the latest
edition of ``Standard Methods for the Examination of Dairy Products'',
