Evaluation of Microbial Load of Beef of Arsi Cattle in Adama Town, Oromia, Ethiopia

Abstract

The study was conducted in Adama town, on carcass samples collected from the Arsi breed of cattle with the objective of evaluating beef microbiological qualities with standard procedures. Carcass samples were randomly chosen at abattoir using systematic random sampling techniques. On the night carcass sampling about 125 cattle were slaughtered and the carcass samples were chosen on every 10 counting. Beef samples were aseptically excised and collected from all parts of the exposed body of carcasses. The methods described by the Nordic Committee on Food Analysis (NMKL) were adopted to analyze each of the parameters considered. Aerobic plate count, total coliform count and fecal coliform counts were significantly different among different sampling days and batches of samples (P<0.05). The mean AP, Total coliform, Fecal coliform, E. coli and staphylococci counts were 1.62×10 5 , 5.29×10 1 , 9.05×10 1 , 8.97×10 1 and 5.54×10 5 , respectively. Salmonella and Shigella bacteria were not isolated per 25 g samples. In Adama, carcasses are normally transported to the butchers' shop either in vans, minibus, taxi, three wheel motor cycle and horse-cart. This exposes the meat to a number of pathogens some of which may be pathogenic. Therefore, since the general hygienic condition of the abattoir and carcass harvesting process was poor, beef consumers in Adama are advised to eat properly cooked beef to avoid intoxication due microbes.

Assessment of microbial quality status of raw beef around Addis Ababa city, Ethiopia

“…However, HPA (2009) indicated aerobic mesophilic count must be less than 7 log cfu/g for raw meat. The present result is relatively higher than mean of fresh meat of 4.53 and 5.210 log 10 cfu/g in Bahirdar and Adama town (Melkamnesh and Mulugeta, 2017;Gebeyehu, et al (2013) and Elsharawy et al (2018) revealed that aerobic plate count of 5.6 Log CFU/g from beef samples collected from Ismailia city abattoir, Egypt. High total aerobic mesophilic bacteria count reveals potential indicators for possible presence of pathogenic microorganisms, poor sanitation and cross contamination.…”

Detection of tetracycline and streptomycin in beef tissues using Charm II, isolation of relevant resistant bacteria and control their resistance by gamma radiation

“…Despite of the improved efforts to ensure the distribution of hygienic meat products, meat products harbouring pathogenic bacteria have increased [26]. In contrast to the results of the current study, low coliform counts in beef cattle (5.29X10 1 cfu/g) was found [27]. However, higher contamination rates within Korean cold duck meats with total aerobic bacterial count of 4-7 log cfu/g and coliforms count of 3.72-5.92 cfu/g has been reported [28].…”

Carcass characteristics of draught cattle released for beef in Eastern Ethiopia

“…The average slaughter weight recorded in this study ( (Table 5) is lower than 68 and 68.2kg that was the study reported by Gebeyehu et al (2018) and Bedhane and Dadi (2016) respectively. This lower result was due to the low slaughter weight and previous agricultural work load or stress.…”

“…Moreover, many scholars reported higher hot dressing percentage for different cattle breeds such as 47.78 ± 2.82% for PO cattle (Haryoko and Suparman, 2009), 47.49% for Boran and 44.93% for Kereyu breeds (Mohammed et al, 2008), 53.15 ± 5.75% for Arsi cattle (Gebeyehu et al, 2018). This disparity in slaughter weight, carcass yield and dressing percentage could perhaps be due to differences in environment, breed type, age of slaughter, the level of fattening, agricultural work load (draught power) and management given which were entirely absent in the present study.…”
