Background:The increasing prevalence of antimicrobial resistance bacteria in meat-producing animals, especially ruminants, represents a major problem for human and veterinary medicine and also could increase the patients' morbidity and mortality. Objectives: The current study aimed to identify the occurrence and antimicrobial susceptibility pattern of Salmonella spp. and Escherichia coli isolated from slaughtered ruminants in East-Azarbaijan province. Materials and Methods: In this study 160 samples (40 sheep, 40 goats and 80 cattle) were examined to isolate the enteric pathogens. The antibiotic resistance was determined by Kirby-Bauer disc diffusion method using 12 antibiotics. Results: A total of one hundred and twenty bacteria were obtained and most of these isolates belonged to these following genera: Escherichia coli (25%), Proteus (18.8%), Salmonella spp. (8.8 %), Pseudomonas spp. (7.5%) and Yersinia spp. (6.3%). Eight (57.1%) of 14 Salmonella spp. isolates and 26 (65%) of 40 E. coli isolates showed resistance to more than four antibiotics, called multiple antibiotic resistance (MAR). Conclusions: Overall, the obtained results emphasize the need for a surveillance and monitoring system to emerge drug resistance in all pathogenic microorganisms in ruminant and other animals.

“…It is clear that the gallbladder is an example of adaptation by the microorganism that Salmonella spp. are highly resistant to bile, which could be shedding slather process and contaminate the food product (5,6). Because of the aforementioned reports, a number of actions have been taken to reduce the prevalence of Salmonella spp.…”

“…Thus dairy producers need to be aware that Salmonella can be found on their farms within apparently healthy cows, which is important in terms of food safety risks (Callaway et al, 2005). Using antimicrobial agents for cattle have been implicated as a source of human infection with antimicrobial resistant (AMR) Salmonella through direct contact with livestock and consumption of raw milk, meat and contaminated materials (Alexander et al, 2009). Antimicrobial resistant Salmonella are increasing due to the use of antimicrobial agents in food animals at subtherapeutic level or prophylactic doses for growth promotion and markedly increase the human health risks associated with consumption of contaminated milk and meat products (Endrias Zewdu and Cornelius 2009), through mutation, acquisition of resistance encoding genes (Fluit, 2005) and irrational use of antimicrobials in food animals (Fluit, 2005;Takele Beyene and Berihun Tesega, 2014).…”

Foodborne bacterial diseases are a serious challenge to human and animal health. Salmonella is a zoonotic foodborne pathogen and the etiologic agent of salmonellosis. A cross-sectional study was conducted from January 2016 to April 2016 on small scale and large scale dairy farms in and around Modjo town, Ethiopia. The main objectives of the study were to isolate and identify Salmonella from lactating cows, personnel's' and equipment at farms and to determine the in vitro antimicrobial resistance profiles of the isolates. A total of 266 samples consisting of fresh cow milk, fecal sample, pooled milkers' hand swab, pooled bucket swab, tank swab, and tank milk were collected from 21 dairy farms (n=20 smallholders, n=1 large scale farm). The samples were examined for the presence of Salmonella following standard techniques and procedures outlined by the International Organization for Standardization. Kibry-Bauer disk diffusion test was used for the antimicrobial susceptibility testing. Salmonella was isolated from 28/266 (10.5%) of the total samples. Out of the 28 Salmonella isolates, 18 (64.3%), 3 (10.7%) and 7(25%) were from lactating cows, personnel's', and equipment, respectively. Out of the 28 isolates subjected to antimicrobial susceptibility testing, all isolates were resistant to at least one or more antimicrobials tested. Accordingly, 96.4% (27/28), 82.1% (23/28) and 75.0% (21/28) isolates were resistant to tetracycline, kanamycin and nalidixic acid, respectively. Multiple drug resistance (resistance to two or more antimicrobials) was detected in 27(96.4%) of the isolates. Multiple antimicrobial resistance was observed in 100% (18/18), 7.4% (2/23) and 100% (7/7) of isolates obtained from lactating cows, personnels', and equipment, respectively. High proportion of multiple antimicrobial resistant isolates (96.4%) in 93Fufa Abunna et al., Ethiop. Vet. J., 2017, 21 (2), 92-108 the dairy farms alerts concern for animal and public health as these drugs is used widely for treatment and prophylaxis in animals and humans.

“…Food borne illness associated with the consumption of foods has been reported in several places in Ethiopia and elsewhere (Estrada-Garcia et al, 2004;Chumber et al, 2007;Ghosh et al, 2007). Antimicrobial use in animal production systems has long been suspected to be the cause of emergence and dissemination of antimicrobial resistant Salmonella (Alexander et al, 2009).…”

Food-borne pathogens are the leading cause of morbidity and mortality in developing countries. Changes in eating habits, mass catering, unsafe food storage conditions and poor hygiene practices are major contributing factors to food associated illnesses. In Ethiopia, the widespread habit of readyto-eat food consumption is potential cause of food borne illnesses. The present study aimed at investigating the prevalence and antimicrobial susceptibility profile of Salmonella species from readyto-eat foods from catering establishments in Jigjiga City and determining susceptibility pattern of bacterial isolates. This study aimed to assess the ready-to-eat foods Salmonella prevalence and antimicrobial resistance pattern of the isolates. In total, various food samples were collected from 120 hotels and processed to detect Salmonella presence. The ready-to-eat food samples were collected and assessed bacteriologically for Salmonella strains. A total of 120 food samples were bacteriologically evaluated. After confirmation, 25 samples (20.8%) were positive to Salmonella. A total of 5 drug resistance patterns were detected among Salmonella isolates. Out of the 25 isolates 10 (40%) were resistant to three antibiotics, 8 (28%) of the isolates were resistant to 4 of the antibiotics tested, whereas 5 (20%) were resistant to two antibiotics, only 1 (4%) isolate was resistant to 1 antibiotic but 1 (4%) isolate was resistant to five antibiotics. The lack of public sanitary facilities can be another hurdle to keep the desirable hands hygiene of the vendors. In this study, it is reported that severity of the current scenario among the hotel worker hygiene and they are the unknowingly playing role in spread of diseases like Salmonellosis.
