The announcements signaled USDA-FSIS' resolve to reduce rates
of foodborne illness outbreaks caused by Salmonella which have
remained flat while overall rates of foodborne illnesses have fallen. It
also was a sign that more research could inform some aspects of the
agency's new strategy to combat Salmonella illness outbreaks.
The US Poultry & Egg Association (USPOULTRY), Tucker, Ga.,
compiled a list of research priorities such as breeder management,
food safety, animal welfare, employee safety, nutrition and other topics.
USPOULTRY highlighted food safety research projects - some new
and some ongoing - the association believes will help regulators as
they develop frameworks and strategies for controlling Salmonella.
For example, a previous study focused on enrichments (a culture that
isolates and makes conditions for growth favorable to an organism)
industry utilizes to determine the concentration of pathogens on
raw poultry.

" There are multiple commercially available enrichment and nonenrichment-based
Salmonella quantification methods, " said Denise
Heard, DVM, MAM, ACPV and vice president, Research Programs at
USPOULTRY. " Those have been developed to support the industry
efforts to reduce the public health impact of Salmonella.
" In raw poultry products, those methods are specifically designed to
determine the concentration of Salmonella in raw poultry products so
that poultry producers can then in turn use the concentration data to
take appropriate action about what to do with their products (and) the
disposition of their products. "
However, Heard said, currently there is no publicly available
research or data that shows the equivalency of those enrichments
versus non-enrichment Salmonella quantification approaches. So, the
objective of a recent USPOULTRY study funded in response to the FSIS
declaring Salmonella an adulterant in breaded chicken products " ...is
to subject routine turkey and chicken samples to different Salmonella
quantification testing with three commercially available methods
currently being used, to provide real-world data for the evaluation of
method equivalency, " Heard explained.
Another project USPOULTRY funded in the spring of 2022 that is
ongoing and relevant considering the USDA-FSIS proposed framework
is titled " Risk Assessment Comparing Alternative Approaches to
Regulating Salmonella and Poultry by Public Health Impact Factors. "
Not all Salmonella and poultry products have an impact on public
health, but current USDA performance standards for raw poultry not
only treat all Salmonella equally, but also treat all contamination levels
equally, Heard said.
" This project that we're funding asked the question, can we reduce
foodborne illness by regulating Salmonella and poultry using metrics
that account for different impacts of specific strains, or high levels on
the risk of the disease, " she said. " So, the objectives for this project
are to build a farm-to-fork, quantitative microbial risk assessment of
Salmonella subtypes and poultry products incorporating different
