flocks, at least four to six weeks, to
clean the breeder farm, too.
"We have found it very useful, in
addition to our routine disinfection,
to come back with formaldehyde
disinfection, either liquid or gas,"
Jensen said. "Formaldehyde is the
best disinfectant ever."
Another recommendation is to
spread liquid lime around the perimeter of the house.
Salmonella monitoring: A
good idea is to routinely monitor
the exterior of the houses to look
for Salmonella. If it is detected, an
additional application of lime can be
done to help prevent it from entering
the house.
Bedding material: Pine wood
shavings dried at a high temperature
are basically sterilized. A humidity
level between 10 to 12 percent is very
inhospitable to Salmonella. However,
these shavings are easily contaminated. Therefore, it's essential to

Feed and water

Heat treatment: Jensen
said there's nothing that will
spread Salmonella through
an operation as quickly as contaminated feed. The best way to eliminate
Salmonella in the feed is using a heat
treatment of 85 degrees Celsius (185
F) for six minutes. This way, a five-log
reduction of coliforms per gram of feed
is achieved.
Heat treatment, however, is
very expensive; it slows down feed
production, and it negatively impacts
the nutrient levels and gravely
affects enzymatic activity.
There are more options available to lower the probability of feed
carrying Salmonella. To achieve a
more typical three-log reduction in
coliforms, a much shorter heating
period of four minutes at 80 C

(176 F) can be used. With the addition of organic acids, this period can
be shortened even more.
Formaldehyde: The compound is
very effective at a maximum rate of
3 kilograms (6.6 pounds) per ton of
feed. Formaldehyde, combined with
organic acids (at 3.6 kg/ton or 7.9 lbs/
ton), also eliminates mold in feed
and has a residual effect preventing
recontamination. It also decontaminates feed lines and feed bins.
Recontamination: To prevent
recontamination of treated feed, it's
important to separate dirty areas
from clean areas in the feed mill. An
enclosed door storage bin and load out
is needed to prevent recontamination
of feed. One of the greatest risks is the
cooling room, where large volumes
of air to cool the feed enter and much
moisture is released. Moisture and
dust from the feed are conducive for
growing Salmonella.
