But there is still some appreManaging preharvest Salmonella to control
hension about vaccination.

"Controlling Salmonella generarticles/37038
ally yields little to no performance
benefits in live production, so production
managers are naturally reluctant to increase costs without
seeing measurable returns," Waldrip said.

Beyond vaccination
Because Salmonella perpetuates through the growout
cycle, Waldrip said it is important to discover the
sources of the problem and to address them. There is
no silver bullet solution for Salmonella incidence.
However, he offered the following suggestions for
control at live production levels:
■ Find out what measures your pullet supplier took to
reduce Salmonella.
■ Guard against Salmonella in the hatchery. Pay attention
to disinfection and cleanliness in all phases, and keep
eggs off the floor. Don't overlook ventilation, as air
handling units can pull in pathogen-contaminated air.
■ Review the procedures at the feed mill. Make sure
steps are taken to protect all raw ingredients from
dust, which can be a source of Salmonella. Also,
feed should be heated to 185 degrees Fahrenheit
(85 C), and that process can't be rushed.
■ Tighten biosecurity procedures and limit human
traffic in barns.
■ Improve control of pests such as live birds, rodents
and darkling beetles.
■ Keep stocking densities to reasonable levels to
ensure cleaner and drier litter.
■ Allow at least an 18-day period between flocks. A
21-day period is even better.
■ Acidify the birds' water at least 72 hours before
processing, but don't lower the pH level to the point
that it discourages drinking.
■ Keep other diseases in check.

Communication is imperative
With some poultry companies, past and present,
the live production teams do not talk to those at the
processing plants.
"There's a real need to connect those two because,
in the end, that's how you control those organisms
of interest - Salmonella and Campylobacter," said
Fulnechek.
In the processing plant, there are many interventions in place to control Salmonella, but Fulnechek
said there is a need to connect the live production
system to the consequences in the plant.
"Live production should do all they can do to
minimize the amount of Salmonella coming to the
processing plant, so their interventions are not overwhelmed. They need to talk so all know of the consequences," he said. ■

SEVENTY PERCENT OF BROILER breeder flocks were
vaccinated at least twice for Salmonella in 2017.
