Description: Das Projekt "Effect of weed management strategies on the risk of enteric pathogen transfer into the food chain and lettuce yield and quality" wird vom Umweltbundesamt gefördert und von Universität Bonn, Institut für Organischen Landbau durchgeführt. The risk of pathogen transfer from soil to plant, here: lactuca sativa var. capitata, under organic farming conditions is to be investigated within the scope of the QLIF project. When brute fertilisers are applied during production, a health risk by consuming raw eadibles, as e.g. lettuce, is often discussed because of the demanding high standard of sanitation. The type of fertiliser might promote transfer of Enterobacteriaceae, and among these possibly human pathogens. Splash-effects during rainfall and irrigation as well as transfer of soil particles during mechanical weed control. Risks of the pathogen transfer into lettuce will be examined by use of different fertilisation and weed control management strategies, the latter being compared regarding their effectiveness in reducing pathogen transfer. Different field trials with organic fertilisation will be performed in 2006 and 2007. The contents of Enterobacteriaceae, coliforms and E. coli are used as sanitation indicators for the assessment of the effectivity of weed control strategies. Therefore, the contents will be measured in soil as well as in plants. Furthermore, the quality of lettuce will be acquired by analyses of nutrient composition and morphological measurements.
