Term
the 10 steps of broiler processing
Definition
-Harvesting
-Slaughter
-Scalding
-Picking
-Transfer
-Evisceration
-Inspection
-Giblet Harvesting
-Washing
-Chilling
Term
[how many?] broilers processed each year
Definition
9 billion
Term
[how many?] processing plants
Definition
185
Term
Average plant does [how many?] birds a day to keep up with demand.
Definition
about 230,000 to 250,000
Term
Processing starts at...
Definition
Harvesting
Term
some details about when feed is withdrawn
Definition
-Primary goal is intestinal emptying (ZERO tolerance for visible fecal material going into chiller…all caucuses would be condemned)
-Withdrawal is 8-12 hours (more than 12 hours they lose weight or live shrink, less and gut may not be empty…It is NOT done to prevent feed wasting).
Term
primary goal of feed withdrawal
Definition
intestinal emptying
Term
why you want the intestines to be empty when processing
Definition
ZERO tolerance for visible fecal material going into chiller…all carcuses would be condemned
Term
when feed withdrawal is done to broilers
Definition
8-12 hours before slaughter; more than 12 hours they lose weight or live shrink, less and gut may not be empty…It is NOT done to prevent feed wasting
Term
this is done before harvesting the broilers
Definition
feed withdrawal
Term
when harvesting is best done
Definition
at night when it’s cool and dark
Term
how broiler harvesting is done
Definition
Primarily still done by hand which is very difficult, so one of the highest paid hourly jobs in processing. (bad hourse, dark and dirty work)
Term
What is the problem with a machine that can do this step?
Definition
you always need a spare in case one breaks down
Term
how hauling of live broilers is done
Definition
Birds placed into “dump coops”and loaded onto large flatbed trucks in the open air. (helps circulate air for fresh oxygen and cool the birds).
Term
how live holding of live broilers is done
Definition
-A shed where the flatbeds can be parked and birds held until processing
-Sheds have fans and spray or misting nozzles to keep birds cool.
Term
the steps of harvesting
Definition
1: feed withdrawn
2: harvesting
3: hauling
4: live holding
Term
the steps of slaughtering
Definition
1: coop dumping
2: hanging
3: stunning
4: killing
5: scalding
6: picking
7: transfer
8: evisceration
9: giblet harvesting
10: washing
11: chilling
Term
how coop dumping is done
Definition
-Forklifts take dump coops from live holding
-Dump coops are tilted and birds slide onto a conveyer belt.
Term
how hanging is done
Definition
Birds are transferred from conveyor belt to shackles in preparation for stunning (lot of manual work in the hangers, considered the toughest job in the plant).
Term
how stunning is done
Definition
An electrical stunning is used to render the bird unconscious in preparation for automated killing
Term
the electricity used for stunning in the U.S.
Definition
In the US we use low voltage (12-40V) and high frequency (500 Hz) for a short duration (3-5 seconds)

The US stunning method is recoverable
Term
how electricity is used in poultry processing in Europe
Definition
In Europe, high voltage is used to electrocute the bird (kill it).
Term
an alternative to electrocution to kill birds
Definition
LAPS (low atmospheric pressure system)
Term
LAPS
Definition
low atmospheric pressure system

birds die from asphyxiation. The post mortem birds are hung from shackels for processing
Term
Problem with LAPS
Definition
identifying DOA (dead on arrival) and it is illegal to process a bird if it isn’t alive going into the plant.
Term
how killing live broilers is done
Definition
After stunning, the bird pass through an automatic killer that places the birds neck against a blade.
Term
how the broiler dies when being killed in processing
Definition
Bird dies from cutting of the jugular and carotid…exsangunation or bleeding to death).
Term
exsangunation
Definition
bleeding to death
Term
details about the bleeding that occurs when a broiler is killed
Definition
Bleeding duration is about 60-120 seconds, which ensures death and that at least 40% of the blood is drained from the bird.
Term
the goal of killing birds like they do in poultry processing
Definition
to insure that only dead birds enter the scalder
Term
what happens if a live bird goes into the scalder?
Definition
If bird is still alive in the scalder, the skin will be bright red and called a cadaver (condemned…a no no)
Term
Purpose of scalding
Definition
to loosen feather for easier feather removal!
Term
Soft scalding
Definition
(50 -54.5 C) Retains the cuticle and yellow pigmentation. Preferred for whole carcass market
Term
Hard scalding
Definition
(55- 60 C) Removes the cuticle so white skin, this process is much better for further processing (much better for batter/breading adhesion).
Term
the goal of picking
Definition
feather removal
Term
when feather removal became automated
Definition
the 60s when it became automated with the rubber picking finger.
Term
“New York Dressed”
Definition
Chickens that have been killed, bled and had the feathers removed
Term
how transfer is done in poultry processing
Definition
At transfer, the bird is removed from the shackle line and passed thru a wall and rehung for evisceration.
Term
goal of evisceration in poultry processing
Definition
to remove the visceral pack and associated organs from the carcass
Term
The USDA-FSIS inspector
Definition
inspects each carcass and the digestive tract must be kept intact and with the associated bird
Term
5 possible outcomes USDA-FSIS inspection
Definition
-passed
-condemned
-viscera only condemned
-trim and reprocessing (affected parts)
-cleaning reprocessing (surface contamination)
Term
offal
Definition
Portions of the carcass not normally consumed by humans
Term
some parts of the chicken that are considered "offal"
Definition
-blood
-heads
-feathers
Term
giblets
Definition
edible organs
Term
some examples of giblets
Definition
-heart
-liver
-gizzard
Term
what most US poultry facilities recover in giblet harvesting
Definition
-heart
-liver
-gizzard
Term
one difference between giblet harvesting in the US and other parts of the world
Definition
in other parts of the word, several other organs (offal) are recovered
Term
why carcasses are washed
Definition
Carcass must be free of any contamination prior to entering the chilling system.
Term
how most plants wash carcasses
Definition
by using a number of manual or auntomated carcass washing cabinets
Term
IOBW
Definition
inside-outside-bird-washer
Term
the goal of chilling broilers
Definition
to chill the carcass to 4C in less than four hours
Term
the most used method of chilling broiler carcasses in the US
Definition
water immersion (works faster, less than an hour)
Term
what supporters say about water immersion of carcasses
Definition
it increases product moistness
Term
what detractors say about water immersion of carcasses
Definition
it increases the water in the carcass thus poultry companies selling expensive water
Term
USDA allow a maximum of ______% water pickup in the chiller
Definition
12%
(must be on label)
Term
popularity of air chilling in the US
Definition
Air chilling has become a popular niche market in the US
Term
Pros of air chilling
Definition
reduce cross contamination
Term
Cons of air chilling
Definition
-drier carcass
-less weight
Term
Overall goal of First or Primary Processing
Definition
to produce a whole poultry carcass known in the industry as a WOG (without giblets)
Term

Definition
w/o giblets
Term
