a) Mastitic
Milk
1) A laboratory examination for the
presence of somatic cells shall be made on all producers' milk at least 4 times
in each 6-month period at irregular intervals. Samples shall be analyzed at an
official laboratory or at a laboratory approved by the Department.
2) Confirmatory testing will be done on milk
when a herd milk sample exceeds any of the following screening test results:
A) California Mastitis Test - Weak positive
(CMT 1+).
B) Modified Whiteside
Test - Positive (1+).
C) Wisconsin
Mastitis Test - WMT value of 18 mm.
3) A confirmatory test for somatic cell count
shall be made on that sample using any of the following methods:
A) Direct Microscopic Somatic Cell Count
(Single Strip Procedure). Pyronin Y - methyl green stain shall be used for
goat's milk.
B) Electronic Somatic
Cell Count.
C) Optical Somatic Cell
Count.
D) Membrane Filter DNA
Somatic Cell Count - The results of the confirmatory test shall be the official
result.
4) Whenever the
confirmatory somatic cell count indicates the presence of more than 750,000
somatic cells per ml, the following procedures shall be applied:
A) The producer shall be notified in writing
by the milk plant with a warning of the excessive somatic cell count.
B) Whenever records reveal two of the last
four consecutive somatic cell counts exceed 750,000 per ml, the Department
shall send a written notice to the producer. This notice shall be in effect so
long as two of the last four consecutive samples exceed 750,000 per
ml.
5) A third milk
sample shall be taken after a lapse of 3 days and within 21 days. If this
sample also indicates a high somatic cell count, the producer's milk shall be
rejected until compliance is obtained. A temporary license shall be approved by
the Department whenever an additional sample of herd milk is tested and found
to conform to requirements. The producer shall be fully reinstated when three
out of four consecutive tests have counts of 750,000 or less somatic cells per
ml. The samples shall be taken at a rate of not more than two per week on
separate days within a 3-week period.
b) Drugs
1)
At least four times in 6 months, at irregular intervals, a separate or
commingled sample of each producer's milk shall be tested for drug residues.
Whenever a producer's milk shows a violative drug residue, this milk shall be
removed from all markets and the Department immediately notified by the
industry certified laboratory. The producer's license shall not be reinstated
until provisions of Section
785.1220 (Drug Residue
Monitoring and Farm Surveillance) are met.
2) All bulk milk pick-up tankers or milk
received directly from the farm bulk tank shall be sampled and tested in
accordance with Section
785.1220. Methods that have been
evaluated by Association of Official Analytical Chemists (AOAC) and recommended
by the Food and Drug Administration at currently referenced levels shall be
used for regulatory action for each drug of concern. FDA shall review the AOAC
evaluations for each test kit and make a determination as to the acceptability
of the use of the method. Regulatory action shall be taken on all violative
results (see Section
785.1220). A result shall be
considered violative if it has been obtained by using a method that has been
evaluated and deemed acceptable by FDA at levels established in memoranda
transmitted periodically by FDA as required by Section
785.1220(c) and
the test completed by a qualified individual as approved by the
Department.
c)
Radionuclides
When notified by Illinois Department of Nuclear Safety,
composite milk samples shall be collected from selected areas and tested for
biologically significant radionuclides.
d) Pesticides and Herbicides
Composite milk samples shall be tested for pesticides and
herbicides at a frequency of once every six months, which the Department
determines to be adequate to protect the consumer. If a sample exceeds
established Food and Drug Administration limits ( 21 CFR 193 and 40 CFR 180),
procedures set forth in Section
785.1210 shall be
followed.
e) Added Water
The presence of added water in raw or pasteurized milk
constitutes adulteration. The presence of added water is indicated by a milk
cryoscope reading of -.524 Hortvet or -.507 Centigrade or higher when tested.
After two occurrences of adulterated milk within a six-month period, the plant
or producer will be required to show cause and reason for the addition of
water. After a third occurrence, the Department will institute administrative
proceedings to revoke the plant or producer's permit.
f) Farm Milk Collection
Milk from producers shall be collected at intervals not
exceeding four calendar days except in emergency situations where roads are
impassible, in which delivery time may be extended an additional day. Milk
determined to contain over 200,000 bacteria per ml shall be collected every two
calendar days. It is the duty of the dairy plant to notify bulk milk
hauler-samplers whenever a maximum two day pick-up and delivery is
required.
