| 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”... |

| Several outbreaks caused by pathogenic bacteria are related to the consumption of raw produce contaminated by animal manure. The majority of these outbreaks have been linked to Salmonella spp. We examined the ability of Salmonella enterica serovar Weltevreden to persist and survive in manure and soil as well as disseminate to, and persist on, spinach roots and leaves. Significantly higher numbers of S. Weltevreden inoculated into manure and applied to soil before planting spinach were found in soil than in pot cultures, where the pathogen had been inoculated directly into soil 14 days postplanting. Moreover, the pathogen seemed to disperse from manure to spinach roots, as we observed a continuous increase in the number of contaminated replicate pot... |

| The aim of present study was to find out the influence of green manures as winter cover crops and their combination with composted cattle manure on metabolomic fingerprinting and microbiological quality of winter wheat in a crop rotation experiment in three organic systems (ORG 0, ORG 1, ORG 2) at the Estonian University of Life Sciences in 2012. |

| Målet med denne undersøkinga var å samanlikna den bakteriologiske kvaliteten, inkludert førekomsten av visse patogen, av økologisk dyrka salat gjødsla med ulike typar storfegjødsel. Feltforsøk med isbergsalat ( Lactuca sativavar. Crispum, ’Iglo’) vart utført i 2001 og 2002. Behandlingane var blautgjødsel, fastgjødsel, kompostert storfegjødsel og mineralgjødsel. Prøvar av jord, gjødsel, gjødsla jord, oppalsplantar, salat og dei ytre blada av salatplantane (i 2002) vart analysert for indikatorbakteriar for fekal forureining (termotolerante koliforme bakteriar (TKB) og Escherichia coli), E. coli O157:H7, Salmonella spp. og L. monocytogenes. Det vart funne statistisk sikker forskjell mellom behandlingane i mengde TKB i gjødsla jord, men det vart ikkje funne... |

| There are indications that the more frequent use of untreated organic residues for fertilization results in increased risk of contamination with human pathogens. Here, we evaluate the ability of two different strains of Campylobacter jejuni to persist in manure and soil as well as spread to spinach plants. It was revealed that different strategies for inoculation of C. jejuni contribute to the persistence of the bacterium in soil, roots, and shoots. Upon inoculation of the bacteria into manure prior to soil application,the amount of C. jejuni subsequently recovered in soil was higher than that from treatments involving the addition of C. jejuni cells to the soil after plant emergence. Irrespective of the bacterial inoculation dose and strategy employed,... |
