The pros and cons of controlled
Controlled atmosphere stunning is coming to the poultry industry.
One expert explained the pros and cons of the new process and
reinforced fundamentals for conventional stunning.
Slaughter innovations like gas
stunning may eliminate unnecessary pain and suffering for broilers
and make the lives of processing
facility workers easier, but getting
the job done correctly will always
require close attention to detail.
Penny Lawlis, a consultant with
Professional Livestock Auditing
Inc., offered a preview of technologies shaping the future of livestock
slaughter and reinforced fundamentals of conventional stunning
as part of the North American
Meat Institute's Animal Care and
Handling Conference on October
19, 2017, in Kansas City, Missouri.
Lawlis, who worked for the government of Ontario, Canada, training parties on humane slaughter
and animal welfare for more than
30 years before going into consulting, said the commitment to doing
it right and attention to all of the
details is the key to successful, humane slaughter.
Introduction to gas stunning
The future of slaughter may
well include gas stunning systems.
Proper stunning is essential to both animal welfare and the final
quality of the product. PicsFive | BigStockPhoto.com
In this system, birds are rendered
insensible by the use of gases
like argon, carbon dioxide or nitrogen. Gas stunning, also called
controlled atmosphere stunning
(CAS), is seeing increased use as
chicken producers commit to using the technology at their slaughter facilities and food companies
commit to purchasing chickens
processed with CAS.
Perdue Foods began operation
of its first CAS system at the end
of 2017. Tyson Foods launched a
pilot program for CAS at two of its
poultry facilities in 2017. In October
2017, McDonald's Corp. vowed to
source its chicken in the U.S. and
Canada from facilities using CAS.
A bevy of restaurants and food
services committed to the Global
Animal Partnership's welfare standards are also pledging to source
chicken processed with CAS, too.
In a traditional slaughter facility, live birds are pulled or dumped
from the coops they are transported in, shackled to the processing
line then stunned and slaughtered.
In a gas system, birds are stunned
before they are handled and are
insensible before being hung on
the line and slaughtered.
There are two different
types of gas stunning processes:
controlled atmosphere killing,
where the birds are dead after
gas stunning, and controlled
atmosphere stunning, where the
birds are rendered unconscious
