“…The prevalence in beef at the abattoir level (11.8%) was similar with the 9.8% rate reported by Nyeleti et al [1], higher than the 2.8% and 3.1% rates [8], 2% [3] from carcass swabs at a beef abattoir, and lower than 42.8% (n = 236) reported from Senegal [21]. It was similar to the rates of 11.9% and 9.8% found in the diaphragm and abdominal muscles, respectively [1].…”

Introduction: Salmonella has been reported from foods and the food production environment, with outbreaks occurring in the human population worldwide. Methodology: A survey on Salmonella in two beef production lines (a beef abattoir line and a processing line) in Addis Ababa, Ethiopia was conducted, with a total of 668 various samples randomly collected from animal-related materials, the environment, and a beef product (mortadella). Results: Overall, a 12.9% prevalence (26.3% from the abattoir line, 5.3% from the processing plant line) was observed. The prevalence in the abattoir line environment (36.6%) was higher than that in animal-related samples (14.7%); the reverse was true for the processing plant line. Out of 86 isolates, 10 serovars were identified, and 8 remained unidentified. The predominant serotypes were S. Saintpaul (32.5%), S. Muenchen (19.8%), and S. Larochelle (12.8%). S. Kastrup and S. London were isolated for the first time in Ethiopia. Conclusions: Data indicate open ports of entry for Salmonella, with possible transfer along the line. Further investigations from farm to fork are recommended in order to identify these positions of entry.

“…The 32.4% positive results in raw beef at the butcheries were similar to findings at the abattoir, lower than the 87.4% rate reported by Stevens et al [21] from retail beef in Senegal and the 60% rate found among samples from a South African slaughterhouse [22].…”

“…In this study, resistance to two or more of antimicrobials (96.4%) was observed. This is higher than studies conducted in Ethiopia (Zelalem Addis et al, 2011;Endrias Zewdu and Cornelius, 2009;Abebe Mekuria et al, 2014;Teshome Tadesse and Anbessa Dabassa, 2012;Anbessa Dabassa and Ketema Bacha, 2012;Fadlalla et al (2012) from Sudan, Stevens et al(2006) from Senegal, and Lagos, Nigeria (Stella et al, 2009). This difference may be due to the increasing rate of inappropriate utilization of antimicrobials in the dairy farms which favors selection pressure that increased the advantage of maintaining strains of bacteria carrying resistance genes (McGeer et al, 1998;Mathew et al, 2006).…”

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.

“…Diarrhoeal diseases are major causes of morbidity and mortality especially among children in developing countries after the malaria and respiratory infections [8] . In Asia, Africa and Latin America, it has been estimated that 2.5 million deaths due to diarrhoea occur each year in children below 5 years of age [9] .…”
