FOOD SAFETY
RESEARCH
air of nature. And so we're subject to
more potential risk. "
The Food Safety Modernization Act's
Produce Rule in recent years updated
standards for growers nationally, but
Smith said that large growers in the
produce industry itself are far beyond
the minimum requirements of the
rule. And CPS sponsors new research
needed, becoming - he said - not " a
source " but " the source " of research
in the field.
CPS awards grants to researchers
internationally as well as at U.S. landgrant
universities. The researchers
are required to publish the research
in a timely fashion, Smith said. CPS
publishes its research findings annually,
and they are online.
Working with companies
CPS works with individual produce
companies on research, and JV Smith
Companies has twice donated to groups
to support projects. One study that JV
Smith donated toward found that stray

dogs and coyotes are possible vectors
for certain strains of E. coli.
In response to the Romaine lettucelinked
outbreak, Smith's company
donated two separate 3-acre " blocks "
or fields where researchers could
replicate large, at-scale Romaine lettuce
production and harvesting for their
experiments.
" Certain plants, they got harvested
and then put on this machine - the
transfer belt - and then went up the
incline belt and into a chute, where the
product itself would fall into the field
bins, " Smith said. " We found a critical
point where it went up the belt and into
the chute where we found pathogens
there consistently and knowing we
had cross-contaminated from prior
plants being harvested. Plants that were
healthy and had been harvested on the
same machine got cross-contaminated
at a particular point, which was
fascinating. It was a good finding. "
Oddly enough, the food safety field
has remained relatively quiet during
the global pandemic. As a vector for
the COVID-19 virus, food remains " low
risk, " Smith said.
" So far, we're not aware of any
transference of the virus to humans
by food, " Smith said. " The pathogen's
transferred by droplets from the
respiratory system - a cough or a
sneeze ... that's the biggest risk. "
