“…1,2 There is also the question of the desirability of animal-based fertility sources, in addition to that of availability. Recognition of the potential transfer of pathogens from animal waste materials to organic plants such as berries and vegetables drives concerns about food safety in animal-based organic crop production systems (Sorensen and Thorup-Kristensen, 2011;Alsanius et al, 2019). In Europe, the place in organic agriculture of animal-based inputs specifically from 1 The organic transition in some parts of Europe similarly necessitated implementation of plant-based fertility systems, particularly in certain arable regions that were managed sans livestock and thus lacked access to animal manure (Hall and Tolhurst, 2007;Løes et al, 2011).…”

Animal-free organic agriculture resides at the margins of sustainable agriculture discourse, practice, and imaginaries, which center animal-based forms of farming. However, the concerns and goals of sustainable agriculture are overwhelmingly consistent with those of many forms of animal-free organic agriculture (AFOA), described as organic farming sans animal production, labor, and byproducts. Despite this sidelining, AFOA has great potential to contribute to a more robust sustainable agriculture movement. In order to emphasize the continuities between animal-based and animal-free sustainable agriculture, this Perspective identifies a number of key similarities between animal-free and animal-based sustainable farming, including mutual foci on soil health and shared opposition to intensive animal agriculture. It contends that beyond being compatible with sustainable agriculture, AFOA holds answers to some of the difficult questions currently and potentially confronting animal-based agriculture, such as projected impacts of climate change on animal agriculture and stability of supply chains for animal-based soil amendments. Barriers to greater inclusion of AFOA into the sustainable agriculture movement exist as well; this piece suggests potential ways to address some of these challenges, including the integration of AFOA into formal sustainable agriculture education.

“…According to the USDA Economic Research Service in 2016, consumers tend to believe that leafy greens produced with organic fertilizer (usually animal manure) without pesticides are safer and healthier than conventionally produced leafy greens [ 6 ]. However, they may ignore the potential health risks of organic vegetables, such as increased ARGs and human pathogens in leafy greens due to the application of animal manure [ 7 ]. Therefore, leafy greens especially organically produced ones are potential hot spots for the transmission of food-borne opportunistic human pathogens (OHPs) [ 8 – 10 ] in light of the “One Health” concept.…”

Food safety of leafy greens is an emerging public health issue as they can harbor opportunistic human pathogens (OHPs) and expose OHPs to consumers. Protists are an integral part of phyllosphere microbial ecosystems. However, our understanding of protist-pathogen associations in the phyllosphere and their consequences on public health remains poor. Here, we examined phyllosphere protists, human pathogen marker genes (HPMGs), and protist endosymbionts from four species of leafy greens from major supermarkets in Xiamen, China. Our results showed that Staphylococcus aureus and Klebsiella pneumoniae were the dominant human pathogens in the vegetable phyllosphere. The distribution of HPMGs and protistan communities differed between vegetable species, of which Chinese chive possessed the most diverse protists and highest abundance of HPMGs. HPMGs abundance positively correlated with the diversity and relative abundance of phagotrophic protists. Whole genome sequencing further uncovered that most isolated phyllosphere protists harbored multiple OHPs which carried antibiotic resistance genes, virulence factors, and metal resistance genes and had the potential to HGT. Colpoda were identified as key phagotrophic protists which positively linked to OHPs and carried diverse resistance and virulence potential endosymbiont OHPs including Pseudomonas nitroreducens, Achromobacter xylosoxidans, and Stenotrophomonas maltophilia. We highlight that phyllosphere protists contribute to the transmission of resistant OHPs through internalization and thus pose risks to the food safety of leafy greens and human health. Our study provides insights into the protist-OHP interactions in the phyllosphere, which will help in food safety surveillance and human health.

“…It has been isolated from livestock, animal excreta, plants, soils, uncultivated fields, and many types of raw and minimally processed vegetables intended for human consumption [3][4][5][6][7]. It can be disseminated through diverse practices, including the animal waste recycling of composts as fertilizers in the organic production of fruits and vegetables, increasing the risk of pathogen transmission between soil, plants, and animals and/or humans [8,9].…”

Animal farming activities can influence soil properties that contribute to the survival of foodborne pathogens like the ubiquitous Listeria monocytogenes. However, the presence of this pathogen in farm-associated soils in Costa Rica has not been studied, which might provide new insights regarding the environmental conditions associated with the establishment of this pathogen. In this work, we correlated the presence of L. monocytogenes with the soil physicochemical properties and bacterial community structure of soils associated with livestock activities, including a dairy barn floor (DB) and a slaughterhouse holding pen (SH). A cropland (CL) was included as an example of soil not associated with animal farming practices. We characterized the presence pattern of L. monocytogenes via culture-dependent and culture-independent techniques (i.e., metabarcoding based on 16S rRNA gene sequencing) and conducted a determination of physical, elemental and chemical parameters with Fourier-transform infrared spectroscopy (FT-IR) to statistically determine the soil properties that correlate with L. monocytogenes’ presence in the soil. L. monocytogenes was isolated from DB samples and SH but not from CL. Subsequently, 16S rRNA gene-based metabarcoding showed that the presence of L. monocytogenes was positively correlated with higher bacterial diversity, while physicochemical analyses revealed that the total hydrogen and nitrogen contents of soil organic matter, pH, and electrical conductivity were the main drivers of L. monocytogenes’ presence. Moreover, a CL sample fertilized with animal-derived products showed DB-like physicochemical properties matching conditions in favor of L. monocytogenes’ presence. Hence, our work emphasizes the significance of soil as a primary source for the widespread dissemination of pathogens, particularly underscoring the necessity for improved agricultural practices to prevent cross-contamination with L. monocytogenes. Additionally, we highlight the importance of further understanding the biotic and abiotic factors in facilitating the establishment of L. monocytogenes.
