Md. Code Regs. 15.11.11.05 - Standards Designed to Control and Prevent Salmonellosis
A. Commercial Flock.
(1) A person having a commercial flock in
Maryland shall have the flock tested in accordance with either §A(2) or
(3) unless the flock is:
(a) Participating in
and meets the requirements of the:
(i) NPIP's
"U.S. Sanitation Monitored" program for egg-type chicken breeding flocks, 9 CFR
145 - 147, or
(ii) "Salmonella
Enteritidis Monitored Flock Program of Pennsylvania" or an equivalent plan of
another state, provided that plan has been approved by the Secretary;
(b) Derived immediately from a
multiplier breeding flock that has been tested and found negative for
Salmonella serotype enteritidis under the procedures outlined in §B;
or
(c) Derived immediately from a
primary breeding flock that has been tested and found negative for Salmonella
serotype enteritidis under §C.
(2) Environmental Sampling/Serological Test.
A person shall allow the Department to:
(a)
Collect environmental samples from all egg belts, elevators, or both, within
caged systems or throughout open floor systems;
(b) Culture or biochemically test these
samples for the presence of Salmonella serotype enteritidis species;
(c) Test, if any flock tests positive to
environmental testing, a random sample of 500 birds per house for the presence
of Salmonella enteritidis antibodies; and
(d) Permanently identify and submit a
statistically significant sample of seropositive birds to an official state
diagnostic laboratory for pathological examination and culture for Salmonella
serotype enteritidis.
(3) Blood Testing. A person shall permit the
Department to:
(a) Test a random sample of
300 birds per house for the presence of Salmonella serotype enteritidis
antibodies; and
(b) Handle birds
testing positive in the manner provided under §A(2)(d).
B. Multiplier Breeding
Flock.
(1) Except as provided in §B(2),
a person having a multiplier breeding flock shall have the flock tested by the
Department as follows:
(a) At least 300 birds
per age group shall be randomly selected and blood tested for the presence of
Salmonella serotype enteritidis;
(b) The flock shall undergo environmental
sampling of nests and litter each month;
(c) At least 30 dead in shell embryos shall
be tested each 3 months; and
(d)
Any serological evidence of infection shall be followed with bacteriological
examination of a statistically significant sample of reactor birds from each
age group and, only if the bacteriology is negative, shall the flock be
considered negative.
(2)
A person owning a multiplier breeding flock is not required to have the flock
tested as described in §B(1) if the flock is participating in and meets
the requirements of:
(a) The NPIP's "U.S.
Sanitation Monitored" program for egg-type chicken breeding flocks;
or
(b) The "Salmonella Enteritidis
Monitored Flock Program of Pennsylvania" or an equivalent program of another
state, provided that plan has been approved by the Secretary.
C. Primary Breeding
Flock.
(1) Except as provided in §C(2),
a person having a primary breeding flock shall follow the same procedures
outlined in §B.
(2) Instead of
randomly selecting and testing 300 birds per age group as provided under
§B(1) for a primary breeding flock a person shall allow the official State
agency to randomly select and test the larger of the following two groups:
(a) 300 birds per age group; or
(b) 1 percent per age group.
D. Effect of Isolating
Salmonella Serotype Enteritidis. If Salmonella serotype enteritidis is isolated
from a flock in Maryland, a person may distribute, offer for sale, or sell
only:
(1) Eggs from that flock that:
(a) Have been pasteurized or otherwise heat
treated to kill Salmonella serotype enteritidis, or
(b) Are to be pasteurized, provided the eggs
are moved to a plant that the USDA has approved for processing egg products;
and
(2) Birds or progeny
from that flock for slaughter, provided the birds are moved for slaughter to an
official establishment to be inspected and either condemned or passed for
cooking only.
