Plant pathologists present research on food safety at APS Annual Meeting in Anaheim, California



Recent advances in food safety research are enabling plant pathologists to gain insight into how dangerous human pathogens, such as strains of E.coli and Salmonella, can survive on fresh fruits and vegetables and what can be done to control future outbreaks.

According to Steve Scheuerell, faculty research associate at Oregon State University’s Department of Botany and Plant Pathology, there has been an increase in reported human disease outbreaks associated with fresh produce over the last couple decades. "When an outbreak occurs, most of the infected produce has already been consumed," said Scheuerell. "Usually recalls won’t help. This is why prevention is key to keeping food safe," he said.


To reduce the potential for the transfer of pathogens to fresh produce, plant pathologists are stressing the need to implement and maintain sanitary growing and harvesting conditions worldwide. "As the U.S. increases its importation of produce, it is increasingly important to us that growers everywhere have good quality irrigation water and sanitary conditions for their workers," Scheuerell said.

"On the domestic front, the National Organic Program has taken the lead in implementing proactive measures to prevent potential contamination of fresh produce with human pathogens," Scheuerell said. Examples include mandated pre-harvest intervals for the application of manure and proposed quality assurance testing regulations for compost tea regulations (a brew of compost with water used as a biocontrol agent or fertilizer). "Using techniques developed by plant pathologists, scientists are just beginning to understand how human pathogens colonize leaf surfaces, and how their survival can be influenced by manipulating leaf surface microflora and environmental conditions," he said.


Plant pathologists from across the country will present more on this topic during the Food Safety as Influenced by Phyllosphere Microflora symposium at the APS Annual Meeting in Anaheim, Calif., July 31-- August 4, 2004. The food safety symposium will be held Tuesday, August 3, 2004 from 9 a.m. to 12 p.m. at the Anaheim Convention Center, Anaheim, Calif. Members of the media are invited to attend annual meeting events; complimentary registration is available.

The American Phytopathological Society (APS) is a non-profit, professional scientific organization dedicated to the study and management of plant diseases, with 5,000 members worldwide.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
