Lack of reliable detection
technology slows PAA
regulation
Commonly employed
sensors cannot
be proven to be
effective. This,
paired with a lack
of federal regulation
for exposure to the
chemical, makes
it difficult for plant
operators.

P

eracetic acid (PAA) is widely used in poultry
plants, but a lack of reliable technology to
measure its concentration in the atmosphere
makes it difficult for regulators and plant operators to
accurately measure the airborne chemical in the plant
so worker exposure can be accurately calculated.

What is peracetic acid
Peracetic acid is a disinfectant chemical used widely
in industrial sectors as varied as food and beverage,
health care, water purification and cosmetics.
In a presentation given as part of the 2019 Poultry
Processor Workshop in Nashville, Tennessee, Paul
Bredwell, the U.S. Poultry & Egg Association's
(USPOULTRY) vice president of environmental
programs, said the chemical is widely used in poultry
processing because of its effectiveness. It's used in
scalders, chillers, dip tanks, belt washers, sprays, the

sanitization of carcasses, organs and parts, as well as
plant clean up.
In a statement, Dr. Kevin H. Dunn, research
mechanical engineer at the Centers for Disease Control's
National Institute for Occupational Safety and Health
(NIOSH) Division of Field Studies and Engineering,
said PAA is a colorless liquid with a characteristic acrid
odor reminiscent of acetic acid, a component of vinegar.
It can be highly corrosive. PAA is always sold in solution as a mixture with acetic acid and hydrogen peroxide
to maintain its stability. The concentration of the acid as
the active ingredient can vary.
Dunn said acute exposure to PAA has been shown
to cause irritation of the eyes, skin and upper respiratory tract. A NIOSH study published in 2018 found
that workers reported watery eyes, nasal irritation,
asthma-like symptoms and shortness of breath when
using a disinfectant containing PAA in a hospital.
