In this multiregional study, generic\u00a0<em>E. coli<\/em>\u00a0was used as an indicator of fecal contamination to identify factors associated with its concentration in manure-amended soils. The analysis included samples from 19 certified organic farms in California, Maine, Minnesota, and Maryland collected over two growing seasons. A zero-inflated linear mixed model was used to assess the association between generic\u00a0<em>E. coli<\/em>\u00a0concentration in soil, and farm-related practices, soil and environmental factors. Generic\u00a0<em>E. coli<\/em>\u00a0concentration in the soil declined in the first 60\u00a0days after manure application (\u03b2: \u22121.00, CI<sub>95<\/sub>: \u22121.17, \u22120.83) before a secondary increase through Day 180. Manure management practices, including use of different types of animal manure and manure application rates, were significantly associated with generic\u00a0<em>E. coli<\/em>\u00a0concentration in soil. Soil nutrients (phosphorus (\u03b2: 0.22, CI<sub>95<\/sub>: 0.15, 0.30)) and micronutrients (zinc (\u03b2: 0.03, CI<sub>95<\/sub>: 0.01, 0.04) and manganese (\u03b2: 0.02, CI<sub>95<\/sub>: 0.01, 0.02)), elevated moisture content (\u03b2: 0.13, CI<sub>95<\/sub>: 0.07, 0.19), and\u00a0<em>Salmonella<\/em>\u00a0(\u03b2: 1.79, CI<sub>95<\/sub>: 1.31,2.23) or\u00a0<em>Listeria monocytogenes<\/em>\u00a0(\u03b2: 0.24, CI<sub>95<\/sub>: 0.03, 0.44) also showed positive association with generic\u00a0<em>E. coli<\/em>\u00a0concentration in soil. Lower wind speed (\u03b2: \u22120.12, CI<sub>95<\/sub>: \u22120.19, \u22120.06), increased precipitation (\u03b2: 0.03, CI<sub>95<\/sub>: 0.01, 0.05), and increased UV index (\u03b2: 0.24, CI<sub>95<\/sub>: 0.15, 0.34) were found to be associated with higher\u00a0<em>E. coli<\/em>\u00a0concentration in manured soil. Overall, the persistence of generic\u00a0<em>E. coli<\/em>\u00a0in manure-amended soil was multifactorial. Effective microbial risk management should incorporate considerations for animal origin of manure, management, environmental, and meteorological factors alongside current USDA National Organic Program standards (90\u2013120\u00a0days) regarding the interval of application of raw manure to harvest of the edible portion of food crops.<\/p>\n","protected":false},"featured_media":0,"template":"","anno":[11378],"ente_che_ha_curato_la_pubblicazi":[],"economia":[],"parole_chiave":[6214,6213,6528,11409,6353,6341],"produzioni":[],"Regioni":[],"sistema_di_controllo":[],"tecniche_produttive":[11100],"class_list":["post-95903","pubblicazioni","type-pubblicazioni","status-publish","hentry","anno-11378","parole_chiave-e-coli","parole_chiave-manure","parole_chiave-pathogens","parole_chiave-soil-amendments","parole_chiave-soil-fertility","parole_chiave-soil-nutrient-management","tecniche_produttive-gestione-del-suolo"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Risk Factors Associated with Generic\u00a0E. coli\u00a0Survival in Soils from Certified Organic Farms - Sinab<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/sinab.it\/pubblicazioni\/risk-factors-associated-with-generic-e-coli-survival-in-soils-from-certified-organic-farms\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Risk Factors Associated with Generic\u00a0E. coli\u00a0Survival in Soils from Certified Organic Farms - Sinab\" \/>\n<meta property=\"og:description\" content=\"Untreated manure is commonly used as a biological soil amendment of animal origin in organic production but may introduce foodborne pathogens into the farm environment.
