Key considerations to minimize
processed poultry rejects
Paying attention to a few key elements from harvesting onward can
help to keep the number of birds rejected at the processing plant low.
EDUARDO CERVANTES LÓPEZ

H

andling with care should be
observed throughout
the entire broiler
processing operation, but
there are a number of
actions from harvest
through final processing
where the risks of the
final carcass being
rejected increase and
where particular attention
needs to be paid to minimize
yield loss.

Capture with care
Particular care must be taken during pre-slaughter
to not rupture the gastrocnemius muscle. If birds
are handled roughly during harvesting the risk of it
breaking and bleeding increases. Similarly, care must
taken not to dislocate the femur.
During harvesting it is important to remember
possible impacts on thigh quality. Capturing birds by
the legs and carrying as many as possible can lead to
femur dislocation, bleeds and bruising.
Broilers' attempts to escape from stressors can also
lead to a deterioration in thigh quality.
Escaping from stressors can lead to birds piling up
on each other. It is worth remembering that the upper
part of the thigh does not have feather cover and that
the skin is exposed, making it more vulnerable to
scratching when birds are fleeing sources of stress.

A failure to ensure that stunning
equipment is properly
adjusted will be paid for in
downgrades.
Eduardo Cervantes López

Products can be administered to birds pre-harvest
to strengthen the skin;
however, capture and caging
should always be conducted
in such a way as to minimize
the stress experienced by the
chickens and reduce the risks of harm
coming to them.

Proper shackling, transport to stun
Birds must be hung on the shackles correctly.
Both legs must be placed evenly into the shackles
and properly adjusted to not cause the birds pain.
Once in the shackles, chickens must remain in
constant contact with the breast comforter and
they are to remain peaceful and relaxed on the
way to the stunner.
Birds must not experience pre-shock on the
approach to the stun bath. Should this occur,
they will lift themselves up while in the shackles
and this affects the shoulder, resulting in a ringshaped bruise.
Without proper stunning, birds will move in
the bleed tunnel, rising and falling in response
