Escherichia coli is one of the causes of gastrointestinal diseases worldwide causing millions of illness annually. The occurrence of Escherichia coli in foods of animal origin in Ethiopia is arguably high due to many reasons like illegal slaughtering of animals in open fields, unhygienic slaughter practices in the abattoirs, and the risk of disease due to this organism is high because of a widespread tradition of raw meat consumption. The objective of this systematic review and meta-analysis was to pool estimates of the prevalence of the organism in different foods of animal origin which is the first of its kind in the country. The literature search was conducted to identify all published articles reporting the prevalence of Escherichia coli in foods of animal origin. From all screened articles, 30 studies were eligible for final systematic review and meta-analysis. Because substantial heterogeneity was expected, random-effects meta-analyses were carried out to pool the prevalence of the organism from different foods of animal origin. The result indicated that between-study variability was high (τ2 = 0.00; heterogeneity I2 = 96.77% with Heterogeneity chi-square = 1298.92, a degree of freedom = 42 and a P-value of = 0.001) with the overall random pooled prevalence of 15% (95% CI = 13%–17%) in foods of animal origin. The result of meta-regression showed diagnosis method used, sample size and study year had contributed significantly to the heterogeneity of studies. This systematic review and meta-analysis showed the level of contamination of foods of animal origin in Ethiopia is high indicating the need for immediate planning of mitigation strategies and detection methods to reduce its level and impact throughout the country.

“…2/370 (0.54%) [22]. Nevertheless, there are also evidences showing an increasing trend of E. coli O157:H7 in meat production systems in Ethiopia [23,24]. In recent studies, the detection of higher proportions of E. coli O157:H7 most probably is associated with the wider use of sensitive detection methods [25].…”

Introduction: Camel meat is a relatively new, emerging meat type that may serve as sources of foodborne pathogens to the consumer. Methodology: A cross-sectional study was conducted to determine the microbiological safety and quality of camel meat from an abattoir and retail houses in Jigjiga city, Ethiopia. A total of 140 camel carcass and retail meat samples (70 each) were examined for the presence and load of Staphylococcus aureus, Escherichia coli O157: H7, Listeria monocytogenes, Campylobacter spp., aerobic bacteria, fecal coliforms (FCs), and yeast and molds (Y&Ms). Presumptive isolates were confirmed using biochemical tests. Results: S. aureus and E. coli O157: H7 populations varied widely between carcasses at the abattoir and retail meat samples. S. aureus and E. coli O157:H7 were detected in 12.1 and 4.3% of the samples, respectively. E. coli O157:H7 counts were significantly higher in retail meat (4.21 ± 0.02) compared to the carcasses (3.99 ± 0.00) at the abattoir (P < 0.05). Out of 140 samples analyzed, 5% were positive for Campylobacter spp. The mean fecal coliforms, and yeast and molds counts were significantly higher in retail meat samples (6.17 ± 0.067 and 4.95 ± 0.067 log10 cfug-1, respectively). L. monocytogenes (11 cfug-1) were detected below the permissible limit (100 cfug-1). Conclusions: This study indicated that the further the process progress, the greater the risk of contamination to the product. Therefore, good hygienic practices at the abattoir and retail houses and strict slaughtering process should be prompted to enhance the overall safety and quality of camel meat.

“…Studies about the occurrence of E. coli O157 in cattle (Abdissa et al, 2017;Atnafie et al, 2017;Haile et al, 2017) and in beef (Assefa, 2019) in Ethiopia are available. With the exception of one study about E. coli in children with diarrhea (Adugna et al, 2015), information on the occurrence of E. coli O157 in diarrheic patients is lacking for Ethiopia.…”

Escherichia coli O157 is a Shiga toxin-producing E. coli causing disease in humans. Cattle are the primary reservoir of the pathogen. Information regarding the contribution of cattle to diarrheal illnesses in humans through consumption of contaminated beef is scarce in Ethiopia. We collected samples from 240 cattle, 127 beef, and 216 diarrheic patients in Bishoftu town in Ethiopia to assess the occurrence and determine the virulence genes, genetic relatedness, and antimicrobial resistance of E. coli O157. E. coli O157 was detected in 7.1% of the rectal content samples from cattle in slaughterhouses, in 6.3% (n = 127) of the beef samples, and in 2.8% of the diarrheic patients' stool samples. All isolates were positive for eae gene, 24 (77%) of them were positive for stx2 gene (21 stx2c and 3 stx2a), whereas stx1 gene was not detected. Molecular typing grouped the isolates into eight pulsed-field gel electrophoresis pulsotypes with three pulsotypes containing isolates from all three sources, one pulsotype containing one isolate from human origin and one isolate from beef. The remaining four pulsotypes contained isolates unique either to beef or to humans. With the exception of 1 multidrugresistant isolate from beef, which was resistant to 8 antimicrobial drugs, the remaining 30 isolates were susceptible to the 14 antimicrobials tested. In conclusion, the finding of genetically similar isolates in cattle, beef, and humans may indicate a potential transmission of E. coli O157 from cattle to humans through beef. However, more robust studies are required to confirm this epidemiological link.
