SUPPLEMENTARY INFORMATION:
Background
The National Poultry Improvement Plan (referred to below as ``the
Plan'') is a cooperative Federal-State-industry mechanism for
controlling certain poultry diseases. The Plan consists of a variety of
programs intended to prevent and control egg-transmitted, hatchery-
disseminated poultry diseases. Participation in all Plan programs is
voluntary, but flocks, hatcheries, and dealers must qualify as ``U.S.
Pullorum-Typhoid Clean'' before participating in any other Plan
program. Also, the regulations in 9 CFR part 82, subpart B, which
provide for certain testing, restrictions on movement, and other
restrictions on certain chickens, eggs, and other articles due to the
presence of Salmonella enteritidis, require that no hatching eggs or
newly hatched chicks from egg-type chicken breeding flocks may be moved
interstate unless they are classified ``U.S. Sanitation Monitored''
under the Plan or they meet the requirements of a State classification
plan that the Administrator of the Animal and Plant Health Inspection
Service (APHIS) has determined to be equivalent to the Plan, in
accordance with 9 CFR 145.23(d).
The Plan identifies States, flocks, hatcheries, and dealers that
meet certain disease control standards specified in the Plan's various
programs. As a result, customers can buy poultry that has tested clean
of certain diseases or that has been produced under disease-prevention
conditions.
The regulations in 9 CFR parts 145 and 147 (referred to below as
the regulations) contain the provisions of the Plan. APHIS amends these
provisions from time to time to incorporate new scientific information
and technologies within the Plan. In this document, we are proposing to
amend the regulations to:
1. Standardize the time frame for the retesting of U.S. Pullorum-
Typhoid Clean breeding flocks retained for more than 12 months by
requiring that the retesting take place a minimum of 4 weeks after the
induction of molt.
2. Establish a ``U.S. Salmonella Monitored'' program for primary
meat-type chicken breeding flocks.
3. Establish a ``U.S. M. Gallisepticum Monitored'' classification
for multiplier meat-type chicken breeding flocks that are not
participating in the ``U.S. M. Gallisepticum Clean'' classification.
4. Establish a ``U.S. M. Synoviae Monitored'' classification for
multiplier meat-type chicken breeding flocks that are not participating
in the ``U.S. M. Synoviae Clean'' classification.
5. Amend the ``U.S. M. Gallisepticum Clean'' and ``U.S. M. Synoviae
Clean'' classifications for meat-type chicken breeding flocks by
augmenting testing when adding (spiking) males.
6. Add a procedure for swabbing or collecting chick papers for
bacteriological examination for salmonella.
7. Add a 4 to 6 week surveillance test for M. gallisepticum to the
``U.S. M. Gallisepticum Clean'' classification for turkeys.
8. Make the qualification test sample size for ``U.S. M.
Meleagridis Clean'' consistent with that for the ``U.S. M.
Gallisepticum Clean'' and ``U.S. M. Synoviae Clean'' classifications
for turkeys.
9. Simplify the description of the procedure for determining the
status of flocks reacting to tests for M. gallisepticum, M. synoviae,
and M. meleagridis.
10. Amend the ``U.S. Sanitation Monitored, Turkeys'' classification
to remove the requirement for the environmental sampling of a laying
house following the removal of a flock from the house.
11. Establish a ``U.S. M. Synoviae Clean'' classification for
waterfowl, exhibition poultry and game birds.
12. Raise from 75 to 150 the number of birds to be tested to
qualify flocks for ``U.S. M. Synoviae Clean'' status.
These proposed amendments, with the exception of number 12, are
consistent with the recommendations approved by the voting delegates to
the National Plan Conference that was held from June 30 to July 2,
1996. Proposed amendment number 12 was approved by the voting delegates
to the National Plan Conference that was held from June 26 to 28, 1994.
Participants in the 1994 and 1996 National Plan Conferences represented
flockowners, breeders, hatcherymen, and Official
[[Page 11112]]
State Agencies from all cooperating States. The proposed amendments are
discussed in greater detail below.
Retesting of U.S. Pullorum-Typhoid Clean Breeding Flocks
We are proposing to amend Secs. 145.23(b), 145.33(b), and 145.43(b)
to provide a minimum time period before the retesting of a U.S.
Pullorum-Typhoid Clean participating breeding flock that is retained
for more than 12 months. The regulations in those sections currently
set forth the criteria under which flocks may qualify for the U.S.
Pullorum-Typhoid Clean classification and provide that flocks that are
retained for more than 12 months shall be retested at the discretion of
the Official State Agency with the concurrence of APHIS.
As breeding flocks, including those retained for more than 12
months, progress through a laying cycle, the shell quality of the eggs
produced tends to deteriorate as calcium and other essential minerals
are depleted from the laying birds. Flockowners may pause the laying
cycle in these birds by inducing molt, which gives the birds the
opportunity to replenish their levels of the depleted minerals. Thus,
when the birds, which are referred to as recycled breeding birds, begin
a new laying cycle, shell quality is back at the proper level.
Research has shown that the stress of molting causes birds that are
affected with salmonella to shed the organism at a higher rate than
during the laying cycle, which means that the best opportunity to
isolate the salmonella organism through testing will come following the
induction of molt. Therefore, we are proposing to amend the
requirements for the retesting of such flocks by requiring that
recycled breeding birds be retested a minimum of 4 weeks after the
induction of molt, rather than at the discretion of the Official State
Agency with the concurrence of APHIS. This proposed change would
standardize the retesting requirements for U.S. Pullorum-Typhoid Clean
flocks retained for more than 12 months and ensure that the
recertification of those flocks is based on testing conducted at a time
when the salmonella organism is most likely to be isolated.
U.S. Salmonella Monitored Classification
We are proposing to amend Sec. 145.33 to establish a ``U.S.
Salmonella Monitored'' classification for primary meat-type chicken
breeding flocks. The proposed new classification, like the existing
``U.S. Sanitation Monitored'' classification available to primary meat-
type chicken breeding flocks, is intended to serve as a means for the
prevention and control of Salmonellosis in hatching eggs and chicks
through an effective and practical sanitation program at the breeder
farm and in the hatchery.
The proposed ``U.S. Salmonella Monitored'' classification differs
from the existing ``U.S. Sanitation Monitored'' classification in two
respects. First, the proposed new classification specifically calls for
the collection of environmental samples at the hatchery from meconium
and chick papers every 30 days; those samples would have to be examined
bacteriologically at an authorized laboratory for salmonella. That
proposed requirement, which is not required by the existing ``U.S.
Sanitation Monitored'' classification, would provide for the continuous
monitoring of the salmonella status of participating hatcheries.
The proposed new classification also differs from the existing
``U.S. Sanitation Monitored'' classification with regard to the use of
vaccines. In the proposed ``U.S. Salmonella Monitored'' classification,
owners of flocks would be allowed to vaccinate their flocks with a
paratyphoid vaccine as a preventive measure, provided that a sample of
350 birds remains unvaccinated to serve as sentinel birds. The sample
of 350 unvaccinated birds would have to be banded for identification
and remain unvaccinated until the flock reaches at least 4 months of
age. Under the existing ``U.S. Sanitation Monitored'' classification, a
flockowner may not vaccinate a flock unless the flock has been found to
be infected with paratyphoid salmonella. The proposed new ``U.S.
Salmonella Monitored'' classification, therefore, would give
participating flockowners the opportunity to take a more aggressive
approach to the prevention of Salmonellosis by allowing them to use
vaccines before there is an indication of the presence of salmonella in
a flock.
New M. Gallisepticum Monitored and M. Synoviae Monitored
Classifications
We are proposing to amend Sec. 145.33 to establish a ``U.S. M.
Gallisepticum Monitored'' classification for meat-type chicken
multiplier breeding flocks that are not participating in the ``U.S. M.
Gallisepticum Clean'' classification and to establish a ``U.S. M.
Synoviae Monitored'' classification for meat-type chicken multiplier
breeding flocks that are not participating in the ``U.S. M. Synoviae
Clean'' classification. Adding these two new ``monitored''
classifications would give flockowners the ability to participate in
disease-monitoring programs for M. gallisepticum and M. synoviae
without incurring the higher testing costs associated with the
``clean'' classifications for those two diseases. The proposed new
classifications would also allow official State agencies and the Plan
to monitor the M. gallisepticum and M. synoviae status of flocks that
would not otherwise be monitored for those diseases.
Under both the proposed ``U.S. M. Gallisepticum Monitored'' and the
proposed ``U.S. M. Synoviae Monitored'' classifications, flocks would
be qualified by testing a sample of at least 20 birds per house for the
classification's disease of concern (M. gallisepticum or M. synoviae,
as the case may be) once the flock reaches at least 4 months of age.
Once qualified, the flock's classification would be retained by
additional tests for the disease of concern conducted on additional 20-
bird samples collected when the flock reaches 36 to 38 weeks and again
at 48 to 50 weeks. Testing at this level would provide a basic level of
monitoring for M. gallisepticum or M. synoviae within a flock but would
not involve the higher expenses incurred by flockowners testing the
larger samples required by the ``clean'' classifications for those two
diseases. To help ensure that the samples of birds would be
representative of all the birds in each house, half of the samples
would have to be drawn from the front of the house and half of the
samples would have to be drawn from the back. Additionally, the ratio
of male to female birds in a sample would have to reflect the ratio of
male to female birds in the house, and samples would have to be labeled
accordingly. Requiring a representative number of male and female birds
to be included in the sample would further ensure that the samples
provide an accurate representation of the birds in the house.
To help prevent the possible exposure of flocks in these
``monitored'' classifications to disease from outside the flock, we
would require participating flockowners handling U.S. M. Gallisepticum
Monitored or U.S. M. Synoviae Monitored products (i.e., poultry
breeding stock and hatching eggs, baby poultry, and started poultry) to
keep those products separate from other products in a manner
satisfactory to the Official State Agency. Because M. gallisepticum and
M. synoviae are egg-transmitted diseases, we would further specify that
chicks from the multiplier breeding flocks in these two ``monitored''
classifications would have
[[Page 11113]]
to be produced in incubators and hatchers in which only eggs from
flocks with the same classification are set. This precaution would
ensure that eggs from a monitored flock would not be set in the same
incubator or hatcher as eggs from a flock that is not qualified under
the ``U.S. M. Gallisepticum Monitored'' or ``U.S. M. Synoviae
Monitored'' classifications. By that same token, we would also prohibit
eggs from these monitored flocks from being set in hatchers or
incubators where eggs from ``U.S. M. Gallisepticum Clean'' or ``U.S. M.
Synoviae Clean'' primary breeding flocks are set, since the eggs from a
monitored flock would be, from a disease-control perspective, of lesser
status than eggs from a flock with clean status.
As a final precaution, chicks from these monitored flocks would
have to be boxed in clean boxes and delivered in trucks that had been
cleaned and disinfected in order to minimize the possibility that the
chicks could be exposed to disease during transport.
Testing of Additional Male Breeding Birds
We are proposing to amend the ``U.S. M. Gallisepticum Clean'' and
``U.S. M. Synoviae Clean'' classifications for meat-type chicken
breeding flocks, Secs. 145.33(c) and 145.33(e), respectively, by adding
a requirement for the testing of a sample of male birds prior to their
addition to a participating multiplier breeding flock. Male birds are
added to breeding flocks to augment the male fertility of the flock,
which tends to decrease over time. Although the birds to be added must
already be drawn from a qualified ``clean'' flock, we believe that
testing a sample of those birds would serve as an additional safeguard
to ensure that the new birds would not have a negative effect on the
disease status of the flock to which they would be added.
We would require that a sample of at least 3 percent of the birds
to be added, with a minimum of 10 birds per pen, be tested for the
classification's disease of concern (M. gallisepticum or M. synoviae) a
minimum of 14 days prior to the date the birds were to be added to the
flock. The birds would have to be tested using either a serologic test
provided for by Sec. 145.14(b) or with a polymerase chain reaction
(PCR)-based procedure approved by the Department as provided by
Sec. 147.6. The male birds from which the sample was drawn would be
considered to be affected with the disease if a serologic test yielded
hemagglutination inhibition titers of 1:40 or higher or if the results
of the PCR tested were positive. If such positive results were
disclosed, the affected male birds could not be added to the flock and
would have to be retested or destroyed in order to prevent the disease
from spreading.
Use of Chick Papers
We are proposing to amend Sec. 147.12 to add another environmental
sampling procedure for use in monitoring for the presence of
salmonella. Specifically, the proposed new procedure would provide for
the collection of samples from chick box papers for bacterial
examination. Chick box papers are used to line the bottom of chick
boxes to catch the meconium droppings produced by the chicks. Chick
boxes are used to transport baby poultry from the hatchery to the
brooding house for grow-out.
Under the proposed procedure, which would be added to the
regulations as Sec. 147.12(c), the Plan participant would collect chick
papers from one out of every ten boxes of chicks placed in a brooding
house. The Plan participant would have the choice of collecting samples
from the papers or sending the chick box papers to a laboratory where
the samples would be collected. For Plan participants who choose to
collect the samples, the proposed new procedure provides detailed
instructions for preventing contamination of the samples, impregnating
the sampling pads with double-strength skim milk, sampling the chick
box papers, and sealing, storing, and transporting the samples.
Likewise, the proposed procedures provide packing and transport
instructions for those Plan participants who choose to send the chick
box papers to the laboratory for sampling and culturing. In either
case, the samples collected from the chick box papers would be cultured
at the laboratory for the presence of salmonella.
The collection of samples from chick box papers is, in essence, a
smaller-scale version of the drag swab technique already used to
collect environmental samples, which is described in Sec. 147.12(a)(3).
Like the drag swab sampling, chick box paper sampling would help
prevent the spread of salmonella in participating flocks by decreasing
the likelihood of false negatives on flock screening tests and reducing
the amount of time required for laboratory diagnoses.
Surveillance and Qualification Tests for Turkeys
We are proposing to amend the procedures in Sec. 145.43(c) for the
``U.S. M. Gallisepticum Clean'' classification for turkeys by adding a
requirement for surveillance testing. Currently, to qualify a flock for
the classification, a random sample of the birds in the flock must be
tested when the birds are more than 12 weeks of age. To retain the
classification, additional samples of 30 birds from male flocks and 60
birds from female flocks must be tested when the birds in the flock are
28 to 30 weeks of age. We are proposing to follow the week 30 test with
continuing surveillance tests conducted every 4 to 6 weeks thereafter.
The tests would be conducted on the same 30 male or 60 female sample
size as the week 30 test and would provide a means of continually
monitoring a turkey breeding flock throughout the laying cycle.
We are also proposing to increase the sample size that must be
tested to qualify a turkey flock under Sec. 145.43(d) for the ``U.S. M.
Meleagridis Clean'' classification. We would increase the sample size,
which currently is set at 60 birds, to 100 birds to make it consistent
with the sample size used in the ``U.S. M. Gallisepticum Clean'' and
``U.S. M. Synoviae Clean'' classifications and to provide flockowners
with more representative samples of birds that would better reflect the
M. meleagridis status of their flocks.
Status of Flocks
We are proposing to amend Sec. 147.6 to simplify the description of
the procedure that is used to determine the status of flocks that react
to tests for M. gallisepticum, M. synoviae, or M. meleagridis. Plan
participants have indicated that the current description of the
procedure in Sec. 147.6 is somewhat confusing and difficult to
interpret. We would, therefore, amend Sec. 147.6 to eliminate
duplication and make the procedure easier to follow. The procedure
itself, however, would not be substantively changed.
U.S. Sanitation Monitored, Turkeys, Classification
We are proposing to amend the ``U.S. Sanitation Monitored,
Turkeys'' classification by removing the requirement for the collection
and examination of environmental samples from laying houses following
the removal of a flock. We believe this requirement, which is currently
located in Sec. 145.43(f)(7), could be removed because the regulations
already provide for environmental samples to be collected and examined
bacteriologically for salmonella when a flock is 12 to 20 weeks of age
(Sec. 145.43(f)(4)) and again when the flock is 35 to 50 weeks of age
and from each molted flock at midlay (Sec. 145.43(f)(6)).
[[Page 11114]]
Because that sampling and testing will have been conducted, and because
a house from which a flock has been removed must be thoroughly cleaned
and disinfected before a new flock may be placed in the house, we
believe that further environmental sampling after a flock has been
removed from a house is unnecessary.
U.S. M. Synoviae Clean Classification
We are proposing to add a new Sec. 145.53(d) to establish a new
``U.S. M. Synoviae Clean'' classification for waterfowl, exhibition
poultry, and game bird breeding flocks. The classification would be
given to qualifying waterfowl, exhibition poultry, and game bird
breeding flocks that are free from M. synoviae and that are maintained
in a manner that prevents M. synoviae from being introduced into the
flock. The sampling, testing, and other criteria under which waterfowl,
exhibition poultry, and game bird breeding flocks would qualify for the
proposed ``U.S. M. Synoviae Clean'' classification would be the same as
those used in the existing ``U.S. M. Synoviae Clean'' classifications
for egg-type chickens (Sec. 145.23(e)) and meat-type chickens
(Sec. 145.33(e)) and would serve the same purpose.
Miscellaneous
We are also proposing to amend Sec. 145.10 by adding three new
illustrative designs to represent the proposed new ``U.S. Salmonella
Monitored,'' ``U.S. M. Gallisepticum Monitored,'' and ``U.S. M.
Synoviae Monitored'' classifications discussed above.
Finally, we are also proposing to correct an oversight dating back
to the last time the regulations were amended. On March 21, 1996, we
published a final rule in the Federal Register (61 FR 11515-11525,
Docket No. 94-091-2) that amended the regulations to reflect the
proposals adopted by the voting delegates to the Plan's 1994 biennial
conference. One of those adopted proposals called, in part, for raising
from 75 to 150 the minimum number of birds tested to qualify an egg-
type chicken or meat-type chicken multiplier breeding flock for ``U.S.
M. Synoviae Clean'' status and raising from 50 to 75 the number of
birds to be tested each 90 days for the flock to retain ``U.S. M.
Synoviae Clean'' status. In the March 1995 final rule, as in the
proposed rule that preceded it (60 FR 35343-35353, Docket No. 94-091-1,
published July 7, 1995), the number of birds to be tested each 90 days
was raised from 50 to 75, but we neglected to raise from 75 to 150 the
number of birds to be tested to qualify flocks for ``U.S. M. Synoviae
Clean'' status. Therefore, to correct that oversight, we are proposing
in this document to amend Secs. 145.23(e)(1)(ii) and 145.33(e)(1)(ii)
to require that a sample comprised of a minimum of 150 birds be tested
for M. synoviae when the flock is more than 4 months of age to qualify
egg-type chicken and meat-type chicken multiplier breeding flocks for
the ``U.S. M. Synoviae Clean'' classification. Increasing the sample
size would provide flockowners with more representative samples of
birds that would better reflect the M. synoviae status of their flocks.
Executive Order 12866 and Regulatory Flexibility Act
This proposed rule has been reviewed under Executive Order 12866.
The rule has been determined to be not significant for the purposes of
Executive Order 12866 and, therefore, has not been reviewed by the
Office of Management and Budget.
The proposed changes contained in this document are based on the
recommendations of representatives of member States, hatcheries,
dealers, flockowners, and breeders who took part in the Plan's 32nd
Biennial Conference. The proposed changes would amend the Plan and its
auxiliary provisions by establishing new program classifications and
providing new or modified sampling and testing procedures for Plan
participants and participating flocks. These changes would keep the
provisions of the Plan current with changes in the poultry industry and
provide for the use of new sampling and testing procedures.
The Plan serves as a ``seal of approval'' for egg and poultry
producers in the sense that tests and procedures recommended by the
Plan are considered optimal for the industry. In all cases, the changes
proposed in this document have been generated by the industry itself
with the goal of reducing disease risk and increasing product
marketability.
Because participation in the Plan is voluntary, individuals are
likely to remain in the program as long as the costs of implementing
the program are lower than the added benefits they receive from the
program. Nine of the 12 proposed amendments involve minor procedural
changes that would have negligible economic consequences. Plan
participants could realize some cost savings because the testing
requirements for the proposed new ``U.S. M. Gallisepticum Monitored''
and ``U.S. M. Synoviae Monitored'' classifications are not as stringent
as the testing requirements for the ``clean'' classifications for M.
gallisepticum and M. synoviae. These savings would, however, likely be
offset by the proposed amendments to the ``U.S. M. Gallisepticum
Clean'' and ``U.S. M. Synoviae Clean'' programs that would require
additional tests for meat-type chicken breeding flocks when spiking
males are introduced. Of the 3,979 pullorum-typhoid clean flocks
currently participating in the Plan, 2,842 flocks are classified as
``U.S. M. Gallisepticum Clean'' and ``U.S. M. Synoviae Clean;'' the
remaining 1,137 flocks are eligible for the proposed new ``U.S. M.
Gallisepticum Monitored'' and ``U.S. M. Synoviae Monitored'' programs.
However, because participation in Plan programs is voluntary, the
Agency could not estimate the number of producers who may participate
in the two proposed new ``monitored'' classifications or use the new
tests.
Under these circumstances, the Administrator of the Animal and
Plant Health Inspection Service has determined that this action would
not have a significant economic impact on a substantial number of small
entities.

(i) U.S. Salmonella Monitored. This program is intended to be the
basis from which the breeding-hatching industry may conduct a program
for the prevention and control of Salmonellosis. It is intended to
reduce the incidence of Salmonella organisms in hatching eggs and
chicks through an effective and practical sanitation program at the
breeder farm and in the hatchery. This will afford other segments of
the poultry industry an opportunity to reduce the incidence of
Salmonella in their products.
(1) A flock and the hatching eggs and chicks produced from it that
have met the following requirements, as determined by the Official
State Agency:
(i) The flock shall originate from a source where sanitation and
management practices, as outlined in Sec. 145.33(d)(1), are conducted;
(ii) The flock is maintained in compliance with Secs. 147.21,
147.24(a), and 147.26 of this chapter;
(iii) If feed contains animal protein, the protein products should
be purchased from participants in the Animal Protein Products Industry
(APPI) Salmonella Education/Reduction Program. The protein products
must have a minimum moisture content of 14.5 percent and must have been
heated throughout to a minimum temperature of 190 deg.F or above, or
to a minimum temperature of 165 deg.F for at least 20 minutes, or to a
minimum temperature of 184 deg.F under 70 lbs. pressure during the
manufacturing process;
(iv) Feed shall be stored and transported in a manner to prevent
possible contamination;
[[Page 11116]]
(v) Chicks shall be hatched in a hatchery meeting the requirements
of Secs. 147.23 and 147.24(b) and sanitized or fumigated (see
Sec. 147.25 of this chapter).
(vi) An Authorized Agent shall take environmental samples from the
hatchery every 30 days; i.e., meconium and chick papers. An authorized
laboratory for Salmonella shall examine the samples bacteriologically;
(vii) An Authorized Agent shall take environmental samples as
described in Sec. 147.12 of this chapter from each flock at 4 months of
age and every 30 days thereafter. An authorized laboratory for
Salmonella shall examine the environmental samples bacteriologically;
(viii) Owners of flocks may vaccinate with a paratyphoid vaccine:
Provided, That a sample of 350 birds, which will be banded for
identification, shall remain unvaccinated until the flock reaches at
least 4 months of age.
(2) The Official State Agency may use the procedures described in
Sec. 147.14 of this chapter to monitor the effectiveness of the egg
sanitation practices.
(3) In order for a hatchery to sell products of this
classification, all products handled shall meet the requirements of the
classification.
(4) This classification may be revoked by the Official State Agency
if the participant fails to follow recommended corrective measures.
(j) U.S. M. Gallisepticum Monitored. (1) A multiplier breeding
flock in which all birds or a sample of at least 20 birds per house has

more than 4 months of age: Provided, That to retain this
classification, a minimum of 20 birds per house shall be tested again
at 36 to 38 weeks and at 48 to 50 weeks at a minimum: And provided
further, That each 20-bird sample should come from two locations within
the house (10 from the front half of the house and 10 from the back
half of the house). A representative sample of males and females should
be sampled. The samples shall be marked ``male'' or ``female.''
(2) A participant handling U.S. M. Gallisepticum Monitored products
shall keep these products separate from other products in a manner
satisfactory to the Official State Agency: Provided, That U.S. M.
Gallisepticum Monitored chicks from multiplier breeding flocks shall be
produced in incubators and hatchers in which only eggs from flocks
qualified under paragraph (j)(1) of this section are set. Eggs from
U.S. M. Gallisepticum Monitored multiplier breeding flocks shall not be
set in hatchers or incubators in which eggs from U.S. M. Gallisepticum
Clean primary breeding flocks qualified under paragraph (c)(1)(i) of
this section are set.

* * * * *
(c) Chick box papers. Samples from chick box papers may be
bacteriologically examined for the presence of salmonella. The Plan
participant may collect the samples in accordance with paragraph (c)(1)
of this section or submit chick box papers directly to a laboratory in
accordance with paragraph (c)(2) of this section.
(1) Instructions for collecting samples from chick box papers:
(i) Collect 1 chick box paper for each 10 boxes of chicks placed in
a house and lay the papers on a clean surface.
(ii) Clean your hands and put on latex gloves. Do not apply
disinfectant to the gloves. Change gloves after collecting samples from
10 chick box papers or any time a glove is torn.
(iii) Saturate a sterile 3-by-3 inch gauze pad with double-strength
skim milk (see footnote 11 to this section) and rub the pad across the
surface of five chick box papers. Rub the pad over at least 75 percent
of each paper and use sufficient pressure to rub any dry meconium off
the paper. Pouring a small amount of double-strength skim milk (1 to 2
tablespoons) on each paper will make it easier to collect samples.
(iv) After collecting samples from 10 chick box papers, place the
two gauze pads used to collect the samples (i.e., one pad per 5 chick
box papers) into an 18 oz. Whirl-Pak bag and add 1 to 2 tablespoons of
double-strength skim milk.
(v) Promptly refrigerate the Whirl-Pak bags containing the samples
and transport them, on ice or otherwise refrigerated, to a laboratory
within 48 hours of collection. The samples may be frozen for longer
storage if the Plan participant is unable to transport them to a
laboratory within 48 hours.
(2) The Plan participant may send chick box papers directly to a
laboratory, where samples may be collected as described in paragraph
(c)(1) of this section. To send chick box papers directly to a
laboratory, the Plan participant shall:
(i) Collect 1 chick box paper for each 10 boxes of chicks placed in
a house and place the chick papers immediately into large plastic bags
and seal the bags.
(ii) Place the plastic bags containing the chick box papers in a
clean box and transport them within 48 hours to a laboratory. The
plastic bags do not require refrigeration.
