SUBJECT: Actions of the 1991 National Conference on
Interstate Milk Shipments
The National Conference on Interstate Milk Shipments
(NCIMS) was held in Louisville Kentucky April 21-26,
1991. At the Conference, the state delegates approved
a number of recommended changes to the Pasteurized
Milk Ordinance (PMO) and related documents. FDA
responded to the Executive Board of NCIMS concerning
each of the recommended actions at the July 25, 1991
Executive Board meeting. The following actions were
mutually concurred. These changes are effective
September 9, 1991, except as noted.
Some of the actual language as adopted by Conference
delegates was modified in order to maintain continuity
with the present language and to insure compatibility
with other existing sections of the PMO. The
modifications have not changed the intent of the voted
actions.

PMO Page 215 Appendix I PASTEURIZATION
EQUIPMENT AND CONTROLS-TESTS
(problem 142)
Add test procedures 8 as follows:
8. CIP TIME DELAY RELAY
Application.--To all high-
temperature short-time pasteurizer
systems in which it is desired to run
the timing pump and/or other flow
promoting devices during the CIP
cycle.
Frequency.--Upon installation and
semiannually thereafter, or whenever
the seal on the time delay relay is
broken.
Criteria.--When the mode switch
on the flow diversion device is moved
from process product to CIP, the flow
diversion device shall move
immediately to the diverted position
and remain in the diverted position
for at least 10 minutes before
starting its normal cycling in the CIP
mode. Simultaneously, the booster pump
shall be turned off and shall not run
during the 10 minute time delay.
Apparatus.--Stopwatch.
Method.--Adjust set point on the
time delay relay equal to or greater
than 10 minutes.
Procedure.--
a. Operate pasteurizer in forward
flow with the mode switch on the flow
diversion device in the process
product position, at a flow rate below
the Flow Alarm set point and above the
Los-of-Signal Alarm set point, using
water above pasteurization
temperature.
b. Move the mode switch on the
flow diversion device to the CIP
position. The flow diversion device
should move immediately to the
diverted position, and the booster
pump should stop running. Start the
stopwatch when the flow diversion
device moves to the diverted position.
c. Stop the stopwatch when the
flow diversion device moves to the
forward position for its initial cycle
in the CIP mode. The booster pump may
start at this time.
d. Record results for the office
record.
e. Install and seal enclosure
over the time delay relay.
Corrective Action.--If the flow
diversion device does not remain in
the diverted position for at least 10
minutes after the mode switch is moved
from process product to CIP, increase
the set point on the time delay relay
and repeat this test procedure. If the
booster pump runs at any time during
the 10 minute delay, the booster pump
wiring is in need of repair.

PMO Page____ Appendix N DRUG RESIDUE
MONITORING AND FARM
SURVEILLANCE
(problem 232)
Add new Appendix N as follows:
Appendix N
Drug Residue Monitoring and Farm Surveillance
This appendix is established to reference
safe levels and/or established tolerances
and to assure that milk supplies are in
compliance with these safe levels or
established tolerances for drug residues in
milk.
I. INDUSTRY RESPONSIBILITIES
A. Monitoring and Surveillance.
Industry shall screen all bulk milk pickup
tankers for beta lactam drug residues.
Additionally, other drug residues shall be
screened for by employing a random sampling
program on bulk milk pickup tankers. The
random bulk milk pickup tanker sampling
program shall represent and include during
any consecutive six months, at least four
(4) samples collected in at least four (4)
separate months. Samples collected under
this random sampling program shall be
analyzed as specified by FDA. (See M-a-75).
Bulk milk pickup tanker testing shall be
completed prior to processing the milk.
Bulk milk pickup tanker samples found to be
positive for drug residues shall be
retained as determined necessary by the
regulatory agency. Industry shall also
record all sample results and retain such
records for a period of six months.
B. Reporting and Farm Traceback.
When a bulk milk pickup tanker is found to
be positive for drug residues, the
regulatory agency shall be immediately
notified of the results and the ultimate
disposition of the raw milk.
The producer samples from the bulk milk
pickup tanker found to be positive for drug
residues shall be individually tested to
determine the farm of origin. The samples
shall be tested as directed by the
regulatory agency.
Further pickups of the violative individual
producer shall be immediately discontinued
until such time that subsequent tests are
no longer positive for drug residues.
Implementation date January 1,1992
II REGULATORY AGENCY RESPONSIBILITIES
A. Monitoring and Surveillance
State regulatory agencies shall monitor
industry surveillance activities by making
unannounced on-site inspections to collect
samples from bulk milk pickup tankers and
to review industry records of the random
sampling program. A review shall include,
but not be limited to the following:
1. Is the program an appropriate routine
monitoring program for detection of
drug residues? Is the program
utilizing appropriate test methods?
2. Is each producers milk represented in
a testing program for drug residues
and tested at the frequency prescribed
in I A. above for drug residues?
3. Is the program assuring timely
notification to the appropriate
regulatory agency of positive results,
the ultimate disposition of the bulk
milk pickup tanker milk, and of the
trace back to the farm of origin? Is
farm pickup suspended until subsequent
testing establishes the milk is no
longer positive for drug residues?
The regulatory agency shall also perform
routine sampling and testing for drug
residues determined to be necessary as
outlined in Section 6 and M-a-75.
B. Enforcement.
If testing reveals milk positive for drug
residues, the milk shall be disposed of in
a manner that removes it from the human or
animal food chain except where acceptably
reconditioned under FDA compliance policy
guidelines. The regulatory agency shall
determine the producer responsible for the
violation.
Penalties. The regulatory agency shall
immediately suspend the Grade A permit of
the responsible producer for a minimum of
two days or equivalent penalty as
determined by the regulatory agency. On
the second occurrence of violative drug
residues in a 12 month period, the
producer's permit shall be suspended for a
minimum of four (4) days or equivalent
penalty as determined by the regulatory
agency. For a third occurrence of
violative drug residues in a 12 month
period, the suspension of permit shall be
the same as the 2nd occurrence and the
regulatory agency shall initiate
administrative procedures pursuant to
revocation of the producer's permit.
Reinstatement. The Grade A producer permit
may be restored to a temporary permit
status after the penalty when a sample
taken from the producers milk in the farm
bulk tank is no longer positive for drug
residues. In no event shall the Grade A
permit of the violative producer be
reinstated by the regulatory agency until
the responsible producer and a licensed
veterinarian have signed a quality
assurance certificate, for display in the
milkhouse, which states that the "Milk and
Dairy Beef Residue Prevention Protocol", is
in place and being implemented for the
dairy herd(s) from which the adulterated
milk containing violative drug residues was
shipped.
Implementation date July 1, 1992
III ESTABLISHED TOLERANCES AND/OR SAFE
LEVELS OF DRUG RESIDUES
"Safe levels" are used by FDA as guides for
prosecutorial discretion. They do not
legalize residues found in milk that are
below the safe level. In short, FDA uses
the "safe levels" as prosecutional
guidelines and in full consistency with CNI
v. Young stating, in direct and unequivocal
language, that the "safe levels" are not
binding -- that they do not dictate any
result, that they do not limit the agency's
discretion in any way, and that they do not
protect milk producers (or milk) from court
enforcement action.
"Safe levels" are not and cannot be
transformed into tolerances that are
established for animal drugs under section
512 (b) of the Federal Food, Drug and
Cosmetic Act. "Safe levels" do not (1)
bind the courts, the public (including milk
producers), or the agency (including
individual FDA employees), and (2) do not
have the "force of law" of tolerances (or
of binding rules).
Notification, changes or additions of "safe
levels" will be transmitted via Memoranda
of Information (M-I's).
AOAC First Action and AOAC Final Action
methods are accepted in accordance with
Section 6. Other drug residue detection
methods may be submitted to AOAC for
evaluation at the safe level or tolerance.
Regulatory action based on each method test
kit may be delayed until the AOAC
evaluation is completed and the method is
found to be acceptable by AOAC and complies
with the provisions of Section 6.
Industry may employ other methods which
have been evaluated by Virginia Polytechnic
Institute and State University (Bishop et
al, 1991) which have been demonstrated to
provide positive results, as described in
Section 6 A, 4. These methods or
equivalently evaluated methods may be
employed until they have been evaluated
through AOAC and accepted by FDA.
Implementation date January 1, 1992
