“…Most national and sub-national studies were conducted in North American and European countries, but three studies originated from SSEA countries [ 35 , 46 , 47 ]. The highest number (10) of national study publications were from the United States [ 11 , 25 – 29 , 32 , 38 , 39 , 42 ].…”

“…Of the 12 risk assessments, seven were quantitative [ 11 , 21 , 38 , 39 , 41 , 42 , 45 ], two were semi-quantitative [ 41 , 43 ], two were qualitative [ 20 , 48 ], and one combined qualitative with quantitative parts [ 44 ]. Seven studies either followed the Codex Alimentarius guidelines for microbial food safety hazards risk assessments (Codex) [ 54 , 55 ], or frameworks based on, or influenced by, them [ 20 , 21 , 39 – 41 , 44 , 48 ]. Another study did not specify any guidelines, but was also in line with the overall Codex framework [ 38 ].…”

“…Sixteen studies started at the outcome and either estimated the contribution of one specific source to it [ 11 , 39 , 42 , 45 ] or attributed it to different sources [ 19 , 25 – 33 , 46 , 47 ]. All microbial subtyping studies [ 19 , 30 – 33 , 46 , 47 ], all investigations of outbreaks [ 25 – 29 ], and four risk assessments [ 11 , 39 , 42 , 45 ] adopted such ‘top-down’ concepts ( Figure 3a ).…”

Twelve were classified as risk assessments [11,20,21,[38][39][40][41][42][43][44][45]48], and the remaining three were of a different study type [35][36][37].…”

Bacterial antimicrobial resistance (AMR) is among the leading global health challenges of the century. Animals and their products are known contributors to the human AMR burden, but the extent of this contribution is not clear. This systematic literature review aimed to identify studies investigating the direct impact of animal sources, defined as livestock, aquaculture, pets, and animal-based food, on human AMR. We searched four scientific databases and identified 31 relevant publications, including 12 risk assessments, 16 source attribution studies, and three other studies. Most studies were published between 2012 and 2022, and most came from Europe and North America, but we also identified five articles from South and South-East Asia. The studies differed in their methodologies, conceptual approaches (bottom-up, top-down, and complex), definitions of the AMR hazard and outcome, the number and type of sources they addressed, and the outcome measures they reported. The most frequently addressed animal source was chicken, followed by cattle and pigs. Most studies investigated bacteria–resistance combinations. Overall, studies on the direct contribution of animal sources of AMR are rare but increasing. More recent publications tailor their methodologies increasingly towards the AMR hazard as a whole, providing grounds for future research to build on.

“…Salmonella causes over one million foodborne infection cases in the US annually, and its accurate and rapid detection continues to be of important interest for both clinical diagnosis and food safety surveillance [ 5 , 40 ]. Compared to traditional serotyping, PCR methods are advantageous because of their simplicity and speed when many samples are to be tested for a few selected serotypes [ 41 ].…”

Salmonella enteritidis is a major causative agent of foodborne illnesses worldwide. As the traditional serotyping and quantification methods are labor-intensive, time-consuming, and expensive, faster and more convenient molecular diagnostic methods are needed. In this study, we developed and validated a rapid duplex TaqMan real-time polymerase chain reaction (PCR) for the accurate identification and quantification of S. enteritidis. The primers and TaqMan probes were designed based on the S. enteritidis-specific gene lygD and the Salmonella genus-specific gene invA. The melt curve and gel electrophoresis analysis showed that the designed primers had potent specificity for the amplification of lygD and invA. The duplex real-time PCR specifically identified S. enteritidis from a panel of 40 Salmonella strains that represented 29 serovars and 12 non-Salmonella organisms. The duplex real-time PCR assay detected four copies of S. enteritidis DNA per reaction. The intra- and inter- assays indicated a high degree of reproducibility. The real-time PCR could accurately detect and quantify S. enteritidis in chicken organs after Salmonella infection. Furthermore, the assay identified 100% of the S. enteritidis and Salmonella genus isolates from chicken egg samples with superior sensitivity after 6 h of pre-enrichment compared to the traditional culture method. Additionally, the most-probable-number (MPN) combined with qPCR and a shortened incubation time (MPN-qPCR-SIT) method was developed for the population determination of S. enteritidis and compared with various enumeration methods. Thus, we have established and validated a new duplex real-time PCR assay and MPN-qPCR-SIT method for the accurate detection and quantification of S. enteritidis, which could contribute to meeting the need for fast detection and identification in prevention and control measures for food safety.
