“…Salmonella Enteritidis and Salmonella Typhimurium were of the most common serotypes associated with human infections from food of animal origins and have been found among human isolates in Italy, 48 Spain, 49 and United States. 50,51 Gantzhorn et al 52 reported that Salmonella Derby and Salmonella Typhimurium were the most prevalent serotypes in Danish pig slaughterhouses. Salmonella Enteritidis and Salmonella London were the common prevalent serotypes in retail meats as well.…”

This study aims to demonstrate the antibiotic resistance and its association with disinfectant and heavy metal resistance in 152 Salmonella isolates recovered from retail foods of animal origins. Susceptibility testing demonstrated that 92.8% isolates were resistant to at least one antibiotic, and the resistance was highest to oxytetracycline (80.9%), followed by trimethoprim (64.5%), amoxicillin (28.9%), ampicillin (28.3%), levofloxacin (21.7%), ciprofloxacin (16.4%), and gentamicin (10.5%), respectively. The bla and tetA genes (44.7%) were commonly present. The qacF and qacEΔ1 genes were detected in 18.4% and 8.6% of all isolates. The Cu-resistance genes pcoR, pcoC, and pcoA were the most prevalent (20.4-40.8%), followed by Hg-resistance gene merA (17.8%) and As-resistance genes arsB (6.6%). The antibiotic resistance was highly associated with disinfectant or certain heavy metal resistance genes. Most notably, the association among Cu-resistance genes (pcoC, pcoR), disinfectant resistance genes (qacF, qacEΔ1), and tetracycline and sulfonamide resistance genes (tet, sul) was significant (p < 0.05). Pulsed-field gel electrophoresis revealed that Salmonella isolates was associated with supermarkets indicating the possibility of crosscontamination in farms or processing environment. This study indicated that retail meats may be a reservoir for the dissemination of antibiotic-resistant Salmonella and using disinfectants for decontamination or metals in livestock may provide a pressure for coselecting strains with acquired resistance to other antimicrobials.

“…The use of disinfectants in food processing premises is important in decreasing the risk of contaminated food products reaching consumers. There have been concerns that bacteria exposed to disinfectants could develop resistance to these, and consequently have a higher risk of developing AMR [60]. In order to examine the prevalence of biocide-resistant Salmonella spp.…”

Overview of Evidence of Antimicrobial Use and Antimicrobial Resistance in the Food Chain

Antimicrobial resistance (AMR) is a global health problem. Bacteria carrying resistance genes can be transmitted between humans, animals and the environment. There are concerns that the widespread use of antimicrobials in the food chain constitutes an important source of AMR in humans, but the extent of this transmission is not well understood. The aim of this review is to examine published evidence on the links between antimicrobial use (AMU) in the food chain and AMR in people and animals. The evidence showed a link between AMU in animals and the occurrence of resistance in these animals. However, evidence of the benefits of a reduction in AMU in animals on the prevalence of resistant bacteria in humans is scarce. The presence of resistant bacteria is documented in the human food supply chain, which presents a potential exposure route and risk to public health. Microbial genome sequencing has enabled the establishment of some links between the presence of resistant bacteria in humans and animals but, for some antimicrobials, no link could be established. Research and monitoring of AMU and AMR in an integrated manner is essential for a better understanding of the biology and the dynamics of antimicrobial resistance.
