UNDRAWN FOWL
KEEPS BEST IN
COLD STORAGE

Undrawn poultry. contrary to the gen
eral impression. keeps better in cold
storage and while passing through trade
channels than does drawn poultry. says
the specialist of the bureau Of chemistry,
United States department Of agricultural,
handling of poultry from the time it is
killed to the time it reaches the consum-
er's table.
Careful observations Of 4 large number
of shipments of both drawn and undrawn
poultry r:ade under commercial condi-
tions, showed that the undrawn poultry
reached the consumer with fewer bac-
terra and with less chemical change ~, IN
composition than the drawn poultry. The
shipments were accompanied by the
scientists from the time the poultry was
killed, while en- route on trains, and
until placed in the cold storage ware
houses, and after being taken out Of cold
storage were followed while being handl-.
ed By wholesalers, conm!ss men and
the retail dealers. Recording thermome-
tcrs accompanied the shipments through
peratures to which the shipments were
subjected We're recorded.
Samples Arc Taken.
Samples were taken from the ship
ment at the time the poultry was killed,
intervals while in storage, at the time
they reached the commission men. again
when the shipment reached the retailers.
and finally when sold to the ultimate
consumer Psychological examination
and chemical analysis were made of all
the samples taken ut the various stages:
Changes az they developed were noted
and studied. Comparisons were made
of the samples taken from the undrawn

drawn poultry. 1t was found that bac.
THEOLOGICAL and chemical indications OF
deterioration developed much quicker in
the drawn poultry. and as the shipments
progressed through the various steps OF
commercial handling. the difference IN
| the signs of deterioration became more
marked. BY the time the shipments
reached the consumer. much OF the drawn
poultry was unfit for food.
The experiments revealed that tho

| cially always resulted in the bird be-
| coming contaminated with bacteria which
| caused spoilagc. These bacteria multiply
rapidly and while their growth is checked

forming an operation-that is. with the
use Of sterile instruments and rubber
gloves and under strictly scientific san

no bacteria contamination in the process

ditions to prevent bacteria contamination
in the drawing of poultry. To produce
this result trained bacteriologist and

in every poultry killing establishment
The ccct Of such process would oe pro-

It is the opinion Of the specialists
therefore. that under usual commerce.
conditions undrawn poultry will kecr
much better than drawn poultry. The
experiments upon which this conclusion
is based were conducted several wears
ago, but continued observation of thou
sands of shipments of opultry under
ordinary commercial conditions ion on;mo, s1ne,

experiments.
