Prevalence of antibiotic-resistantSalmonellain retail organic chicken

Abstract

PurposeThe objective of this study was to determine Salmonella prevalence, antimicrobial-resistant phenotypes, and their genetic relatedness in frozen organic chicken collected at retail level in Turkey.Design/methodology/approachRetail packs (n = 348) of cut-up chicken parts (breast, leg quarter and drumstick) and whole chicken carcasses were purchased from a central hypermarket in Diyarbakir (Southeast Anatolia Region in Turkey) and from a large online retailer in Turkey. The retail packs were paired by part type, brand, production date, and sell-by date. The chicken samples were analyzed for the presence of Salmonella spp., and then isolates were screened for antibiotic susceptibility, class I integron, and genetic similarity.FindingsSalmonella prevalence in retail frozen organic chicken samples was 6.3 percent; however, the prevalence by parts, leg quarter, drumstick, breast, and whole chicken was 2.1 percent, 10.4 percent, 10.4 percent, and 0 percent, respectively. Salmonella prevalence was significantly higher in samples obtained from the hypermarket (9.2 percent) compared to online retailer (3.8 percent). All the isolates were serotype Infantis, genetically similar (highly clonal), and 68.2 percent harbored class I integron. All isolates were resistant to ciprofloxacin (drug of choice to treat salmonellosis in human), and 86.3 percent of the isolates were multidrug-resistant.Originality/valueSalmonella prevalence in organic chicken meat, regardless of the retail market source in Turkey, may pose a health risk to consumers especially with the high prevalence of multi-drug resistant phenotypes. Findings inform researchers and the public about the safety of organically produced chicken and the potential health risk to consumers.

Prevalence and multidrug resistance of Enterococcus species isolated from chickens at slaughterhouses in Nakhon Ratchasima Province, Thailand

“…In this study, the prevalence of MDRE isolates resistant to several antibiotics (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) was 65.22% (105/161). Our results agrees with those of Desire et al [30], who reported an MDRE prevalence in laying hens of 73.17% (30/40), with the number of antibiotics ranging from three to eight.…”

“…Available at www.veterinaryworld.org/Vol.15/November-2022/4.pdf Although the ESBL-encoding gene, particularly TEM, has frequently been detected in chickens and chicken meat worldwide [2], Class 1 integron has been identified as the most common resistance integron. This integron comprises gene cassettes of distributed AMR in most Gram-negative enteric bacteria, which majorly influences the antimicrobial and MDR nature of many bacterial species [3]. However, these genes have not been fully addressed in commensal bacteria.…”

“…AMR=Antimicrobial resistance 2. AM=Antimicrobial 3. The statistical significance level was set at 95% confidence.…”

“…Although the ESBL-encoding gene, particularly TEM, has frequently been detected in chickens and chicken meat worldwide (Antunes et al 2016), class 1 integron has been identi ed as the most common resistance integron. This integron comprises gene cassettes of distributed AMR in most in Gram-negative enteric bacteria, which majorly in uences the antimicrobial and MDR nature of many bacterial species (Guran et al 2020). However, these genes have not been fully addressed in commensal bacteria.…”
