" Get in there and think like the pathogens.
Look beyond the superficial stereotypes about
their behavior. Learn how they adapt, how they
survive and what makes them die. "
- TREVOR SUSLOW, EXTENSION RESEARCH SPECIALIST, UC DAVIS
packing and processing facilities. Once
it has adapted to non-killing stresses, it
can tolerate heat, freezing, pH extremes
and sanitizers.
After outbreaks in 2020 and 2021,
the dry bulb onion industry partnered
with CPS on research to identify
production practices that may contribute
to salmonella contamination and how
to reduce related food-safety risks.
Oregon State University's Joy WaiteCusic
and Texas A&M's Vijay Joshi are
thinking like pathogens - and also
like crops. Waite-Cusic reported at CPS'
June Research Symposium that overhead
irrigation resulted in more prevalent and
persistent E. coli contamination (used
as a surrogate for salmonella) of onion
bulbs than drip irrigation.
Both projects are relevant to other
produce and production conditions.
Once completed, they should add to
our understanding of how salmonella
interacts with fresh produce and
responds to environmental conditions.
The research should also point to safer
plant breeding options and lower-risk
water application options, plus other crop
management, harvest, curing, storage
and processing practices.
Meanwhile, another recent CPS project
identified a potential tool for bacterial
pathogen control postharvest. University
of Georgia's Kevin Mis Solval found
that low-cost infrared cameras added
to common smartphones worked as well
as higher-cost technology to measure
produce surface and core temperatures
across indoor environments.
Is there a call to action here?
TS: Leaders should empower and
develop the skill base of their food safety
professionals so they really understand
how to dissect research and are able to
figure out the " so what " of research -
to watch for both the very positive side
but also red flags. To help, CPS has
created a really amazing, never-existedbefore
network of experts of all different
kinds. You don't have to figure this out
on your own.
