Can Ozone Treat Pathogens in Fresh Produce?
With the recent e-coli breakouts in romaine lettuce, growers
have been trying to find ways to remove pathogens from fresh
produce. Helmut Leili, a veteran agronomist who happens to be
the CEO of Cardinal Fresh, suggests ozone treatments can deal
with pathogens and bacteria in produce products. “Ozone is a very
powerful and natural oxidizing gas that simply and quickly reverts
back to natural oxygen,” Leili says. “The technology of creating
ozone is well developed and used extensively in many applications,
such as municipal water treatment, hospital sanitation, and medical
treatments such as blood transfusion.” Millions of dollars worth of
fresh fruits and vegetables are recalled weekly due to potentially
deadly pathogens hiding in crevices of produce. Leili has been
researching ozone application solutions almost five years and
gotten to a point that allows ozone to be applied to exported fruit
and vegetables in a safe and effective manner.

UK Funds Major Plant Diseases Research Program
The British government is investing $22.8 million for a major
bacterial plant diseases research program, which will be conducted
under the umbrella of several UK research councils. The initial
aim of the program is to prepare for the possible introduction
and spread of the devastating plant
pathogen Xylella fastidiosa (Xylella),
described by the European
Commission as “one of the
most dangerous plant bacteria
worldwide.” The nasty, insect-
transmitted pathogen infects 500 species
including crops, ornamental plants, and
trees. In Italy, one million olive trees are
dying from Xylella in a disease called
Olive Quick Decline Syndrome. So
far, Xylella has not been reported
in the UK. Xylella is a bacterial
pathogen transmitted by
insects feeding on the xylem
tissues that transport water
in plants. These bugs include
froghoppers in Europe. The
common froghopper feeds on a
variety of plants, and is commonly
found across most of Northern
Europe, including the UK.
