Risk factors associated with the prevalence of Listeria monocytogenes in manured soils on certified organic farms in four regions of the United States

In "Frontiers in Sustainable Food Systems" - Biological soil amendments, including raw or untreated manure, are currently used to improve soil fertility, especially in organic operations that prohibit use of synthetic fertilizers. However, addition of untreated manure may pose a risk of contamination of fresh produce by pathogens of public health significance, including Listeria monocytogenes.

Una ricerca negli USA: i periodi di attesa imposti dall'USDA riducono efficacemente i rischi per la sicurezza alimentare nelle aziende biologiche

Le pratiche di agricoltura biologica regolamentate, negli Stati Uniti,  dall'USDA, limitano con successo il rischio di colonizzazione del suolo da parte di batteri patogeni, secondo un recente studio americano (si può scaricare QUI) pubblicato sulla rivista Frontiers in Sustainable Food Systems.

L’Organic Center USA riprende uno studio europeo sulle alternative agli input esterni nelle aziende biologiche

Sebbene gli agricoltori biologici si astengano dall'uso di prodotti chimici inorganici e fertilizzanti sintetici, le piante e il bestiame possono essere trattati con input esterni approvati. E nonostante le sostanze approvate per l'uso nel biologico debbano avere conseguenze negative minime per il loro utilizzo, è importante rivedere e valutare regolarmente il loro potenziale impatto sull'ambiente e sulla salute umana.

Postharvest Quality and Storability of Organically Versus Conventionally Grown Tomatoes: A Comparative Approach

Published in “Biology and Life Sciences Forum” -  In various parts of India, tomatoes are grown using eco-friendly indigenous organic manures prepared from cow products, for sustainable food production by small and marginal farmers. The main objective of the study was to compare the postharvest quality characteristics and storability between organically grown tomatoes using indigenous organic manures and those grown conventionally.

Survival and Persistence of Foodborne Pathogens in Manure-Amended Soils and Prevalence on Fresh Produce in Certified Organic Farms: A Multi-Regional Baseline Analysis

Biological soil amendments of animal origin (BSAAOs), including untreated (e.g., raw or aged manure, or incompletely composted manure) and treated animal products (e.g., compost), are used for crop production and as part of soil health management. Application of BSAAO's must be done cautiously, as raw manure commonly contains enteric foodborne pathogens that can potentially contaminate edible produce that may be consumed without cooking.

Reshaping agro-food system and closing its nitrogen cycle: the potential of combining dietary change, agroecology, and circularity

After World War II, the evolution of Europe’s agro-food system has been marked by intensified use of synthetic fertilizers, territorial specialization, and integration in global food and feed markets. This evolution led to increased nitrogen (N) losses to aquatic environments and the atmosphere, which, despite increasing environmental regulations, continues to harm ecosystems and human well-being.
