It was the aim of this study to detect points of risk in meat and product contamination; to assess the prevalence of Salmonella Addis Ababa Universität elektronische Bibliothek Dissertation and E.
The study was conducted from December to April in two beef production and supply lines. All samples were examined for Salmonella and E. Possible sources and transmission routes of Salmonella serotypes were tracked based upon genetic similarity and differences of the obtained same serotype relation. All Salmonella and E. Within both lines, sampling occasions, locations and directions in the production, processing and supply of the final product were considered and taken into account for data management and analysis.
Numerical data from spoilage bacteria counts were calculated in logarithmic function and compared using single and paired t-tests. Abattoir line Spoilage bacteria: Due to learn more here heavy contamination of the abattoir spoilage bacteria were only assessed at the processing plant line.
Salmonella prevalence was higher for abattoir environment Saintpaul, followed by 5. In this line, a prevalence of S. The PFGE pattern showed 1, 2 and 6 pulsotypes with 1 to 14 ratios of isolates to Computer-Dissertation in serotypes and 1 to 7 pulsotypes Addis Ababa Universität elektronische Bibliothek Dissertation 1 to 2. Based on genomic similarity, transmission routes were identified for S.
Saintpaul SSaX2S. Muenchen SMuX1S. With regard to E. This prevalence essentially agreed with prevalences of the environment Prevalence at individual sampling locations ranged from Processing plant line Parameters tested here were spoilage bacteria, Salmonella and E. Highest APC of 5. EBC ranged from high 3. This difference ranged from 2. Using APC, microbiological quality of products in total was found to be good in In click, by EBC A total of 23 Salmonella isolates 5.
Prevalence in theenvironment 5. Only one isolate was observed in a single supermarket, the others being negative. A total of seven serotypes with a high ratio of prevalence to proportion 1. Unidentified Salmonella strains were also obtained from this line. Possible transmission of S. London SLoX1 was Addis Ababa Universität elektronische Bibliothek Dissertation on the 1st sampling occasion from raw beef samples to working tables which were also positive on the 2nd sampling occasion.
A similar pulsotype within each of S. Anatum SAnX1S. London SLoX1 and S. Muenchen SMuX1 from raw beef on the 1st, 2nd and 6th sampling occasions was observed, respectively Addis Ababa Universität elektronische Bibliothek Dissertation that the contaminated meat was coming from the same sources. The overall prevalence along the processing plant line There was no difference in prevalence among and between products from all supermarkets.
Susceptibility to OT was Resistance Addis Ababa Universität elektronische Bibliothek Dissertation high A total of 55 High resistance was detected in S. Strains of higher resistance were Addis Ababa Universität elektronische Bibliothek Dissertation at the abattoir line Single-drug resistant strains were more frequent Multiple drug resistance MDR in the strains was only 3. Resistance to OT was frequently observed.
Distribution of strains resistant to individual drugs in both abattoir and processing plant lines was 1. Furthermore, their susceptibility to AML was between This was true overall for isolates from the abattoir line and the processing plant line. High frequencies of resistant strains to OT A total of Higher frequencies of resistant strains were observed at the processing plant line Single-drug resistant isolates Isolates resistant to OT were frequently observed.
The total distribution of strains resistant to individual drugs both at the abattoir and at the source plant line showed differences.
The extent of resistance to each drug in increasing order was PB 1. Observation of Salmonella and E. Higher Salmonella prevalence In this study, occurrence of S. London was reported for Ethiopia for the first time.
Larochelle showed indistinguishable profiles. Resistance was high to oxytetracycline. Findings revealed prevalence of the agents and the need for improvement, regular monitoring and application of HACCP during production, processing, handling and supply of products. Furthermore, resistance of Salmonella and E.
This drug is marketed, it is popular and widely used in the veterinary sector in Ethiopia. The further use of this drug thus should be questionned in light Addis Ababa Universität elektronische Bibliothek Dissertation the high prevalence of resistant strains Addis Ababa Universität elektronische Bibliothek Dissertation the country.

Abstract Increasing solid waste Addis Ababa Universität elektronische Bibliothek Dissertation is a major concern worldwide, with least developed countries LDCs particularly affected due to ineffective kaufen Überzeugungsreden management systems.
This article assessed the current status of solid waste management in Addis Ababa Universität elektronische Bibliothek Dissertation from waste generation to disposal. Solid waste generation in LDCs averages 0. Waste collection is also low and due to irregular waste collection, many people in Думаю, Wie schreibe ich ein Dissertationsthema?
Вашем resort to illegal practices such as illegal dumping or open burning of wastes. Sanitary landfilling is almost non-existent in LDCs with some of the few landfills present severely lacking in effective leachate or gas collection systems. While recycling is carried out in some LDCs, the most common practice is to collect recyclables for exportation.
Similarly, composting of solid waste exists mainly on small-scale while biogas plants present in LDCs are used mostly for treatment of animal manure. Some of the challenges faced by LDCs include lack of funding, infrastructure, legislations, knowledge, and awareness on solid waste issues. However, there is a huge potential for job creation in the solid waste management field including waste collection, recycling, composting and even sanitary landfilling.
