“…Moreover, some reports also showed that ENR and CIP posed a severe ecological risk to the soil environment (Li et al, 2015;Zhao et al, 2019) [47,48]. Besides, the RQs were lower in soil than that of wastewater samples, indicating that the composting technology can effectively reduce the ecological risk posed by antibiotics [49,50]. Moreover, antibiotics also can be degraded in soil due to microbial degradation, soil adsorption, photolysis, and so on.…”

Scientific interest in pollution from veterinary antibiotics (VAs) on intensive animal farms has been increasing in recent years. However, limited information is available on the seasonal pollution characteristics and the associated ecological risks of VAs, especially about the different scale farms. Therefore, this study investigated the seasonal pollution status and ecological risks of 42 typical VAs (5 classes) on three different scale pig farms (breeding scales of about 30,000, 1200, and 300 heads, respectively) in Tianjin, China. The results showed that large-scale pig farms usually had the highest antibiotic pollution levels, followed by small-scale pig farms and medium-scale pig farms. Among different seasons, antibiotic contamination was more severe in winter and spring than that in the other seasons. Tetracyclines (TCs) usually had higher proportions (over 51.46%) and the residual concentration detected in manure, and wastewater samples ranged from not detected (ND)-1132.64 mg/kg and ND-1692.50 μg/L, respectively, which all occurred for oxytetracycline (OTC) during winter. For the antibiotic ecological risks in the effluent, we found high-risk level of 12 selected VAs accounted for 58% in spring, and 7 kinds of VAs were selected in the amended soil, but nearly all the antibiotics had no obvious ecological risks except OTC (spring and summer). All these data provided an insight into the seasonal variability and the associated ecological risks of antibiotics on intensive pig farms, which can provide scientific guidance on decreasing antibiotic contamination to enhance environmental security in similar areas.

“…They exhibit various advantages including low cost of operation and maintenance, absence of power consumption, noise and offensive odors, and considerable improvement in the effluent quality [27]. Many studies have reported that CW-based treatment processes are capable of removing different types of micropollutants [28,29], including steroidal hormones such as estrogens, progestogens, androgens, and glucocorticoids [26]. The major hormone removal mechanisms include biodegradation (aerobic or anaerobic), sorption, and plant uptake [26].…”

“…Fortunately, the direct transmission of pathogens from poultry and livestock animals to human via food products is usually minimized, as proper food processing, handling, and cooking methods are destroying them in the food production chain. However, the most important concerns for the use of antibiotics as growth promoters in poultry and livestock farming are: (1) the use of sub-therapeutic amounts of antibiotics could promote the development of antibiotic-resistant strains through selection pressure; (2) the release of antibiotic-resistant bacteria in the environment; (3) the transfer of antibiotic-resistant genes to non-resistant bacteria in the environment or human flora by horizontal (processes of conjugation, transduction, or transformation) or vertical transfer; and (4) the release of small amounts (residuals) of antibiotics and their metabolites in the environment could promote de novo mutations or evolution of sensible bacteria, leading to antibiotic resistance [ 43 , 44 , 45 , 46 , 47 ].…”

Insights in the Development and Uses of Alternatives to Antibiotic Growth Promoters in Poultry and Swine Production

The overuse and misuse of antibiotics has contributed to the rise and spread of multidrug-resistant bacteria. To address this global public health threat, many countries have restricted the use of antibiotics as growth promoters and promoted the development of alternatives to antibiotics in human and veterinary medicine and animal farming. In food-animal production, acidifiers, bacteriophages, enzymes, phytochemicals, probiotics, prebiotics, and antimicrobial peptides have shown hallmarks as alternatives to antibiotics. This review reports the current state of these alternatives as growth-promoting factors for poultry and swine production and describes their mode of action. Recent findings on their usefulness and the factors that presently hinder their broader use in animal food production are identified by SWOT (strength, weakness, opportunity, and threat) analysis. The potential for resistance development as well as co- and cross-resistance with currently used antibiotics is also discussed. Using predetermined keywords, we searched specialized databases including Scopus, Web of Science, and Google Scholar. Antibiotic resistance cannot be stopped, but its spreading can certainly be hindered or delayed with the development of more alternatives with innovative modes of action and a wise and careful use of antimicrobials in a One Health approach.
