“…Manure of animal origin serves as a significant reservoir of ARGs due to the promiscuous use of antibiotics in the animal setting, and this consequently elevates the level of antibiotic resistance within agricultural soil particularly after the application of antibiotics-and ARGs-rich animal manure, thus posing environmental and human health problems (Zhang et al, 2019). A considerable quantity of ARGs are present in the manure and deposited on agricultural soil during soil amendment (Ghosh & LaPara, 2007;Heuer, Schmitt, et al, 2011).…”

“…During composting process, manure is stabilized through biological degradation, a process that reduces the levels of persisting organic pollutants (Poulsen & Bester, 2010;Sadef, Poulsen, Habib, Iqbal, & Nizami, 2016) and antibiotics (Liu et al, 2015;Mitchell et al, 2015). Just like organic materials whose physicochemical status af- It is thought that the incorporation of the bulking agent during manure composting enhances the degradation of antibiotics and prevents the spread of ARGs within the manure (Zhang et al, 2019).…”

The incidence of antibiotic resistance within and beyond the agricultural ecosystem: A concern for public health

2020

The agricultural ecosystem creates a platform for the development and dissemination of antimicrobial resistance, which is promoted by the indiscriminate use of antibiotics in the veterinary, agricultural, and medical sectors. This results in the selective pressure for the intrinsic and extrinsic development of the antimicrobial resistance phenomenon, especially within the aquaculture‐animal‐manure‐soil‐water‐plant nexus. The existence of antimicrobial resistance in the environment has been well documented in the literature. However, the possible transmission routes of antimicrobial agents, their resistance genes, and naturally selected antibiotic‐resistant bacteria within and between the various niches of the agricultural environment and humans remain poorly understood. This study, therefore, outlines an overview of the discovery and development of commonly used antibiotics; the timeline of resistance development; transmission routes of antimicrobial resistance in the agro‐ecosystem; detection methods of environmental antimicrobial resistance determinants; factors involved in the evolution and transmission of antibiotic resistance in the environment and the agro‐ecosystem; and possible ways to curtail the menace of antimicrobial resistance.

“…Previous research has indicated that many vegetables contain ARB, possibly from soil or land‐applied fertilizer (Schwaiger, Helmke, Hözel, & Bauer, 2011). Nonetheless, the choice of bulking agent, in particular, can be critical, as it can alter the dominant microbial taxa within a compost pile (Zhang et al., 2019). Our findings potentially shed light on the cause of the hindrance of ARG reduction in swine manure compost when rice and mushroom [ Pleurotus eous (Berk.)…”

Corn stalk residue may add antibiotic‐resistant bacteria to manure composting piles

Manure is commonly used as a fertilizer or soil conditioner; however, land application of untreated manure may introduce pathogens and antibiotic-resistant bacteria (ARB) into the soil, with harmful implications for public health. Composting is a manure management practice wherein a carbon-rich bulking agent, such as corn (Zea mays L.) stalk residue, is added to manure to achieve desirable carbon/nitrogen ratios to facilitate microbial activities and generate enough heat to inactivate pathogens, including antibiotic-resistant pathogens. However, when comparing compost piles and stockpiles for ARB reduction, we noticed that bulking agents added ARB to composting piles and compromised the performance of composting in reducing ARB. We hypothesized that ARB could be prevalent in corn stalk residues, a commonly used bulking agent for composting. To test this hypothesis, corn stalk residue samples throughout Nebraska were surveyed for the presence of ARB. Of the samples tested, 54% were positive for antibiotic-resistant Escherichia coli or enterococci using direct plating or after enrichment. Although not statistically significant, there was a trend wherein the use of pesticides tended to result in a greater prevalence of some ARB. Results from this study suggest that bulking agents can be a source of ARB in manure composting piles and highlight the importance of screening bulking agents for effective ARB reduction in livestock manure during composting.

“…As shown in Table 1 , physical methods such as adsorption, sedimentation, flocculation, and filtration only separate the antibiotic residues from the water and generate problematic products such as brine and contaminated adsorbents. Alternatively, biological approaches have recently emerged, and most antibiotic residues in the environment can be removed through this route [36] , [37] , [38] . However, the artificial introduction of active organisms into aquatic environments may disrupt the ecological balance of their biomes, which may cause irreversible ecosystem damage.…”
