Microbial quality of organic and conventional vegetables from Polish farms
International Journal of Food Microbiology(2018)
摘要
Microbiological analyses of lettuce, radish, carrot and beetroot were conducted to determine the effect of production system (organic and conventional) on the microbial quality of vegetables in Poland. During 2010–2014 growing seasons, 600 organic and 372 conventional samples were collected from certified farms. The vegetables were analyzed for aerobic mesophilic bacteria, yeasts and molds, Enterobacteriaceae, coliforms and Escherichia coli according to Polish standards. The farmer's survey was conducted to collect information on farm management practices. The index (from 0 – no risk to 4 – high risk) of potential contamination of the produce by human pathogens, related to fertilization system was developed.
