| Bacterial pathogens have increasingly been identified as disease causing agents in vegetable-linked outbreaks. Consumers nowadays show higher demands for fresh or minimally processed fruits and vegetables, and at the same time potential sources of pathogen infestation are increasing due to the more frequent use of animal manures as fertilizers in organic than in conventional agriculture. On the other hand, a higher antagonistic potential against invading pathogens is implicated from the more diverse microbiota in organic soils. Vegetable-associated outbreaks in Europe are not well documented, and guidelines are missing for reducing risks of pathogen infestation. Thus, a survey on organically grown vegetables has been carried out by the “PathOrganic”... |

| Vigorous seedlings are an important base for vegetable production. Beside the availability of appropriate amounts of nutrients, the health of seedlings is decisive. Soil-borne diseases are a challenging problem in organic seedling production. Here, we present results on the development of disease-suppressive growing media. Three aspects were examined: (i) use of different components of growing media (peat, coconut fiber, wood fiber, compost), (ii) influence of selected organic nitrogen fertilizers and (iii) use of different microorganisms (including commercial biocontrol agents (BCA)). Three plant-pathogen systems were used in this study: cucumber-Pythium ultimum, cress-Pythium ultimum and basil-Rhizoctonia solani. Green waste compost showed a good... |

| The project BIOSEEDLING “Robust planting material from seeds to young plants - an implementation oriented chain approach” aims to find improved production procedures for vegetable seedlings of lamb’s lettuce. First, the production of lamb’s lettuce seeds of a professional seed producer was analyzed and the effect of harvest time and seed size on the germination and disease rate in the seeds was studied. Then, using seeds naturally infected by Peronospora valerianellae and Acidovorax valerianellae, several seed disinfection methods were compared: aerated steam, hot water, sodium hypochlorite, ethanol, Calcium hydroxide, and compost pellet. After testing methods for the identification of the seed pathogens and the quantification of the infection, an... |

| DEUTSCH Über den EHEC-Erreger, der in Deutschland zu über dreissig tragischen Todesfällen geführt hat, ist viel spekuliert worden. Unterdessen konnten die Verbreitungswege nahezu aufgeklärt werden, während die Entstehung des Krankheitserregers noch weitgehend unklar ist. Im Zusammenhang mit dem EHEC-Ausbruch wurde auch die Frage erörtert, ob bestimmte Landwirtschaftsmethoden (zum Beispiel gemischte Betriebe mit Tierhaltung und Pflanzenbau oder die organische Düngung von Gemüse) oder ob gewisse Hygienisierungsmethoden für frische, konsumfähige Produkte(wie zum Beispiel die Verwendung von schonenden, weniger Rückstände verursachenden organischen Säuren) das Risiko erhöhen könnten. Diese Dokumentation geht nicht auf die aktuellen Fälle von EHEC in... |

| Pilot tests were performed with a process combination of electrodialysis and ozonation for the removal of micropollutants and the concentration of nutrients in urine. In continuous and batch experiments, maximum concentration factors up to 3.5 and 4.1 were obtained, respectively. The desalination capacity did not decrease significantly during continuous operation periods of several weeks. Membrane cleaning after 195 days resulted in approximately 35% increase in desalination rate. The Yeast Estrogen Screen (YES), a bioassay that selectively detects oestrogenic compounds, confirmed that about 90% of the oestrogenic activity was removed by electrodialysis. HPLC analysis showed that ibuprofen was removed to a high extent, while other micropollutants were... |

| PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens (e.g. Salmonella enterica, pathogenic E. coli, Campylobacter spp., Listeria monocytogenes) in organically grown plant produce. The project aims at evaluating whether organic production poses a risk on food safety and addresses the food chain by taking into consideration potential sources of pathogen transmission (e.g. animal manure). In addition, it evaluates whether organic production may reduce the risk of pathogen manifestation. From a European perspective, vegetable-linked outbreaks are not well investigated. Within the PathOrganic project, surveys of organically grown vegetables are carried out in... |

| PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens in plant produce. The project evaluates whether organic production poses a risk on food safety, taking into consideration sources of pathogen transmission (e.g. animal manure). The project also explores whether organic versus conventional production practices may reduce the risk of pathogen manifestation. In Europe, vegetable-linked outbreaks are not well investigated. A conceptual model together with novel sampling strategies and specifically adjusted methods provides the basis for large-scale surveys of organically grown plant produce in five European countries. Critical control points are... |
