The transmission of antimicrobial resistance (AMR) between food‐producing animals (poultry, cattle and pigs) during short journeys (< 8 h) and long journeys (> 8 h) directed to other farms or to the slaughterhouse lairage (directly or with intermediate stops at assembly centres or control posts, mainly transported by road) was assessed. Among the identified risk factors contributing to the probability of transmission of antimicrobial‐resistant bacteria (ARB) and antimicrobial resistance genes (ARGs), the ones considered more important are the resistance status (presence of ARB/ARGs) of the animals pre‐transport, increased faecal shedding, hygiene of the areas and vehicles, exposure to other animals carrying and/or shedding ARB/ARGs (especially between animals of different AMR loads and/or ARB/ARG types), exposure to contaminated lairage areas and duration of transport. There are nevertheless no data whereby differences between journeys shorter or longer than 8 h can be assessed. Strategies that would reduce the probability of AMR transmission, for all animal categories include minimising the duration of transport, proper cleaning and disinfection, appropriate transport planning, organising the transport in relation to AMR criteria (transport logistics), improving animal health and welfare and/or biosecurity immediately prior to and during transport, ensuring the thermal comfort of the animals and animal segregation. Most of the aforementioned measures have similar validity if applied at lairage, assembly centres and control posts. Data gaps relating to the risk factors and the effectiveness of mitigation measures have been identified, with consequent research needs in both the short and longer term listed. Quantification of the impact of animal transportation compared to the contribution of other stages of the food‐production chain, and the interplay of duration with all risk factors on the transmission of ARB/ARGs during transport and journey breaks, were identified as urgent research needs.

[24][25][26][27] In addition, mixing of animals at lairage prior to slaughter may contribute to different profiles from the farmgenerated ones. Another source of variance may be related to the sensitivity and more specifically, differences in the diagnostic techniques applied for isolation of Salmonella.…”

Antimicrobial resistance in Salmonella from food animals is recognized as a major problem worldwide. Monitoring animals destined for slaughter for antimicrobial resistance that could potentially enter the food chain poses a challenge and abattoirs therefore might be a potential candidate checkpoint for monitoring antimicrobial resistance patterns on farms. A complicating factor however is the impact of lairage on Salmonella detected in pigs at slaughter. The aim of this study was to compare antimicrobial resistance (AMR) patterns in Salmonella spp. collected from swine postslaughter (cecal samples) and upon arrival (fecal samples) at the abattoir to evaluate the feasibility of using slaughterhouse samples for surveillance of prevailing AMR Salmonella on the farm. Eighty-fourSalmonella isolates were recovered from a large, Midwestern US abattoir between September and November, 2013. All isolates were tested for phenotypic antimicrobial resistance to 12 antimicrobials using the broth microdilution assay (NARMS). Whole-genome sequencing was used to identify the AMR genes harbored by the strains. Significant differences were observed between the phenotypes of the isolates, and their genotypes but no significant difference between the genotypic resistance patterns was found. The results indicated that the AMR profiles of Salmonella spp. post-slaughter cannot be predicted from the pre-slaughter samples obtained at the abattoir. Further research that considers the genetic diversity of tested isolates and the test power for genotypic statistical analysis needs to be conducted in order to improve the performance of WGS-inferred antimicrobial susceptibility.AMR SURVEILANCE OF SALMONELLA SPP.

“…La carne de diferentes especies, entre ellas la de bovino, funciona como reservorio de su principal agente causal: Salmonella enterica subsp. enterica, de aquí en adelante referida como Salmonella (2) . Particularmente, la carne de res molida se ha vinculado con brotes recientes de salmonelosis en América del Norte (3) , por lo cual se considera uno de los principales vehículos de exposición humana a Salmonella.…”

El objetivo fue estimar la frecuencia de contaminación, diversidad de serotipos y tipificación por multilocus (MLST) de Salmonella enterica (SE) en linfonodos y carne molida de bovino. Para ello, se analizaron 1545 muestras provenientes de 400 canales bovinas. El muestreo incluyó linfonodos superficiales (LNS) y profundos, carne molida magra y con grasa, obtenidas en estación cálida (abril-julio) y fría (septiembre-diciembre) durante 2017 y 2018. Los aislamientos puros se sometieron a secuenciación completa del genoma. Con estos datos, se realizó la predicción in silico de serotipos y del perfil de MLST. En total, se obtuvieron 78 aislamientos de SE (5% del total de muestras analizadas). La frecuencia de contaminación se asoció con el tipo de muestra (2=23.7, P<0.0001) y con la época del año (2=20.3, P<0.0001), siendo mayor en LNS (9.7%) y en estación cálida (7.0%). Los serotipos predominantes fueron Anatum y Reading (n=23 cada uno), Typhimurium (n=11) y London (n=9). El perfil de MLST de cepas de los serotipos Typhimurium (ST 19 y 34) y Kentucky (ST 198) se ha reportado previamente en aislamientos involucrados en casos clínicos. Se concluye que los linfonodos y la carne molida de res son reservorios de SE de importancia en salud pública, especialmente durante los meses cálidos del año. Por tanto, es necesario establecer medidas encaminadas a prevenir la diseminación, a lo largo de la cadena productiva, de las cepas asociadas con animales aparentemente sanos.
