Hog operation disinfectants discussed
NEWARK, Del Cleanup and
disinfection are two vitally im
portant parts of any swine
management program. Most
producers are more familiar than
they would like to be with the
cleanup process. Disinfectants are
another matter.
Why should you use a disin
fectant 9 “It’s cheap insurance,”
says University of Delaware ex

Kephart. “We often talk about

Formaldehyde is probably the
most effective disinfectant
available, Kephart says. It kills
nearly all types of microbes and
viruses under a wide variety of
conditions. Unfortunately, at high
concentrations its fumes are very
irritating. When used as a gas it’s
an excellent fumigant, but it must
be used with caution. Solutions of
formaldehyde also provide good
germicidal activity and are safer
to use than the gas.
Creosols and phenols, like for
maldehyde, can produce ob
jectionable odors. That's
especially true with creosol, the
specialist says. But they have
excellent resistance to organic
debris. So if a swine facility con
tains a lot of wood or hidden
crevices, these compounds might
be the best choice. They also
provide good results in foot baths.
Quarternary ammonium
compounds are not recommended
for disinfecting livestock facilities,
since organic matter quickly
inactivates them. They have
limited effect on viruses, fungi and
spores. They do work well for
sanitizing dairy and food handling
equipment. But since these
compounds are neutralized by
soap, be sure that surfaces are
rinsed well before using the
quarternary ammoniums.
lodophors are a combination of
iodine and detergents. They aren’t
very effective in the presence of
organic material. And they
provide only limited activity
against viruses and salmonella
bacteria. But the lodophors are
non-irntating and rarely cause
skin reactions. For producers who
wash and disinfect sows before
farrowing, one of the lodophors is a
good choice.
Sodium hydroxide provides good
germidical properties under most
conditions. And it’s cheap. But it’s
also very caustic and can cause
serious burns, Kephan cautions
Use accordingly.
“So, to get the most from your
disinfectant dollar, think about
how and where you plan to use the
disinfectant,” he advises
“Remember that good sanitation
is a must An effective cleanup will
remove 95 percednt of the con
tamination. And it allows the
disinfectant to penetrate and do
the job you expect.”
