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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
