Assessment of Bacteriological Quality of Sold Meat in the Butcher Shops of Adigrat, Tigray, Ethiopia
2 Abstract: The study was carried out from November 2011 to April 2012, through which purposive sampling methodology was used to assess the bacteriological quality of sold meat in abattoir and butcher shop of Adigrat. On a total of 80 meat samples (20 samples from each stage; abattoir and butcher house of hanging meat, minced meat and refrigerated meat). The mean values of bacterial load of hanging meat, minced meat, abattoir meatand refrigerated meat were 5.5x10 , 6.5x10 , 3.2x10 and 3x10 CFU/g respectively indicating high 777 7 mean values of microbial load in the hanging meat and minced meat sales with statistically significant difference (P<0.05).Theresult also indicated that 13.75, 46.25 and 40% of the meat are acceptable,marginally acceptable and unacceptable respectively. The major bacterial pathogens isolated were Escherichia coli; Staphylococcus aurous Streptococcus species and non-lactose fermenting bacteria. Most of the isolated bacteria were susceptible for the commonly used antimicrobials.Careless handling of meat at the slaughtering places and butcher shops affect the quality of meat which indicated as the presence of contamination. Therefore, particular attention to meat hygienic should be strengthened in both butcher houses and abattoirs workers.
Bacteriological Quality Assessment of Raw Beef Sold in Sylhet Sadar
This study was conducted to assess the bacteriological quality of fresh raw beef sold in different markets of Sylhet Sadar. A total of seventy five (75) fresh raw beef samples were randomly collected from seven  major markets (Shibgonj, Mirabazar, Kazitula, Ambarkhana, Madina market, Bandar bazar and Sheikh ghat) of Sylhet Sadar. Total Viable Count of the samples ranged between 2.5 × 10 5 to 2.25 × 10 8 cfu/g. Acceptability for consumption of these samples as satisfactory, acceptable and rejected were 40, 32 and 28%, respectively. A total of 115 bacterial isolates of 5 genera were identified including gram negative Escherichia coli [15(10%)], Salmonella spp. [20(13.33%)], Klebsiella spp. [30(20%)], Enterobacter spp. [10(6.67%)] and gram positive Staphylococcus spp. [40(26.67%)]. The presence of these organisms in fresh meat from conventional beef is alarming. DOI: http://dx.doi.org/10.3329/agric.v13i2.26654 The Agriculturists 2015; 13(2) 09-16
Investigations on the rôle of organic matter in plant nutrition
1. As the result of decomposition of green manure in a swamp soil, the coarse fractions (including coarse and fine sand) of the surface layer (first 3 inches) decreased by 11·2 per cent. while the fine ones (silt+clay) increased by 9·8 per cent. in the course of 43 days. The effect was less pronounced in the manured soil maintained at 60 per cent. saturation, while no alteration was to be noticed in the case of the unmanured specimens. 2. Treatment with dilute hydrochloric acid prior to dispersion had no appreciable effect on the estimates of mechanical composition obtained in the different cases. Loss in solution was also comparatively small. 3. The silica-sesquioxide ratio increased slightly as the result of decomposition of green manure in swamp soil. The composition of the fine fractions was also altered, the total percentages of the oxides of iron, aluminium and silicon increasing from 90·5 to 99·3 in the course of 71 days. 4. The practical significance of the above and related observations has been discussed.
