“…The selected studies and their main characteristics are described in Table 2 . Of the reviewed studies ( n = 19), seven were conducted in the The United States of America [ 11 , 30 , 31 , 32 , 33 , 34 , 35 ], four in Europe (one in Portugal [ 10 ], one in France [ 2 ], one in Lithuania [ 36 ], and one in Bulgaria [ 3 ]), six in Africa (one in Argelia [ 37 ], one in Kuwait [ 22 ], two in Egypt [ 23 , 38 ], and two in Cameroon [ 4 , 21 ]), one in Asia (Korea [ 39 ]), and one in the Middle East (Iran [ 6 ]). Most of the studies were conducted in poultry farms (10 out of 19–53%) [ 10 , 11 , 21 , 29 , 31 , 33 , 35 , 36 , 37 , 38 ], four (21%) in big poultry farms [ 3 , 4 , 22 , 30 ], four (21%) in small poultry farms [ 2 , 5 , 32 , 34 ], and one in a big duck farm [ 39 ].…”

In poultry farms, the mixture of bedding material, chicken excrement, and feathers seems to play an important role in pathogen development which may contribute to a potential risk of zoonosis, spreading the disease through the food chain. The purpose of this study was to analyze microbial contamination in bedding material and other matrices as well as potential antimicrobial resistances in chicken production facilities, and also to identify the sampling techniques and assays used. This study evidences the available data published, following the PRISMA methodology. Among the environmental samples, surface swabs were frequently used as a passive sampling technique. Morphological identification was performed in all studies. From all the matrices, the bedding material was the most contaminated. Most studies focused on bacterial contamination, with Salmonella sp. and Campylobacter sp. being commonly reported and three studies evidenced fungal contamination, being Penicillium sp.- and Aspergillus sp.-dominant. Mycotoxin assessment was only performed in one study, being identified in all bedding samples. The screening for bacteria resistance evidenced bacteria multidrug resistance; however, fungal susceptibility to azoles was not assessed in any of the analyzed studies. Briefly, this review evidences the microbial contamination in poultry facilities, emphasizing animals’ bedding as a potential source of contamination. Additionally, this study contributes to a sampling and analysis protocol proposal to assess the microbial contamination in this setting. Additionally, the knowledge gaps identified highlight the need of further research regarding microbial contamination and toxicological potential on animals’ bedding in order to mitigate the exposure in poultry pavilions.

“…The isolation rate of Salmonella in farms was 23.6%, similar to the 21.9% found in the study by Martelli et al (2017) . Kim et al (2021) found that the positive rate of Salmonella contamination increased significantly after the introduction of ducklings to the farm. In contrast, the duck farm in this study had strict biosecurity measures of removing weak ducklings after they hatch, which may lead to a lower rate of Salmonella isolation in the farm than in the hatchery.…”

“…At present, there are many large duck farms in China that have complete duck production chains, from hatching and breeding to sales. Recent studies have shown that waterfowl, such as ducks, are also important sources of Salmonella ( Martelli et al, 2016 ; Kim et al, 2021 ). Salmonella infection in ducks is a recessive infection, however, it can also cause serious clinical symptoms with high mortality and threat to food safety ( Grigar et al, 2017 ).…”

“…China is the largest producer and consumer of waterfowl, such as ducks and geese, and related products ( Wang et al, 2017 ). Recent studies have shown that waterfowl are an important source of Salmonella ( Wang et al, 2020a ; Kim et al, 2021 ) and often transmit Salmonella due to open-yard feeding ( Murray et al, 2021 ); however, relevant systematic studies on Salmonella prevalence in these species have rarely been reported.…”

Salmonella enterica is a widespread foodborne pathogen with concerning antimicrobial resistance (AMR). Waterfowl are a major source of Salmonella transmission, but there are few systematic studies on Salmonella prevalence in waterfowl species. In this study, 126 Salmonella isolates (65 collected in 2018–2020 and 61 collected in 2002–2005) were obtained from waterfowl samples in Sichuan, China. Their serotypes, pulsed-field gel electrophoresis (PFGE) types, and phenotypic and genotypic AMR profiles were systematically examined. The isolates were distributed in 7 serotypes, including serovars Enteritidis (46.0%), Potsdam (27.8%), Montevideo (7.9%), Cerro (6.3%), Typhimurium (4.8%), Kottbus (4.0%) and Apeyeme (3.2%). Their PFGE characteristics were diverse; all isolates were distributed in four groups (cutoff value: 60.0%) and 20 clusters (cutoff value: 80.0%). Moreover, all isolates were multidrug resistant, and high rates of AMR to lincomycin (100.0%), rifampicin (100.0%), sulfadiazine (93.7%), erythromycin (89.7%), ciprofloxacin (81.0%), and gentamicin (75.4%) were observed. Finally, 49 isolates were subjected to whole-genome sequencing, and a wide variety of AMR genes were found, including multiple efflux pump genes and specific resistance genes. Interestingly, the tet(A)/tet(B) and catII resistance genes were detected in only isolates obtained in the first collection period, while the gyrA (S83F, D87N and D87G) and gyrB (E466D) mutations were detected at higher frequencies in the isolates obtained in the second collection period, supporting the findings that isolates from different periods exhibited different patterns of resistance to tetracycline, chloramphenicol and nalidixic acid. In addition, various incompatible plasmid replicon fragments were detected, including Col440I, Col440II, IncFIB, IncFII, IncX1, IncX9, IncI1-I and IncI2, which may contribute to the horizontal transmission of AMR genes and provide competitive advantages. In summary, we demonstrated that the Salmonella isolates prevalent in Sichuan waterfowl farms exhibited diverse serotypes, multiple AMR phenotypes and genotypes, and AMR changes over time, indicating their potential risks to public health.
