Objective: To determine the occurrence of CTX-M producing Escherichia coli(E. coli)from cattle feces in Bogor slaughterhouse, Indonesia.Methods: A total of 220 cattle feces samples were collected from Bogor slaughterhouse from March to April 2015. Presence of extended-spectrum beta-lactamase(ESBL) producing E. coli was detected by disc diffusion test based on the recommendation from Clinical and Laboratory Standards Institute(2014). Bacterial strains which were confirmed as producing ESBLs were further analyzed for the presence of bla genes of the ESBL by PCR.Results: The results showed that CTX-M producing E. coli isolates were detected in 19 samples from 220 samples(8.6%). The b-lactamase genes detected were CTX-M-1(n = 10) and CTX-M-9(n = 9). All of the CTX-M producing E. coli isolates showed multidrug resistance phenotypes to at least four antibiotics. The highest incidence of antibiotics resistance was showed to ampicillin(100.0%), cefotaxime(100.0%), and cefpodoxime(100.0%), followed by streptomycin(84.3%), trimethoprim-sulfamethoxazole(73.7%), erythromycin(52.6%), kanamycin(26.3%), doxycycline(10.5%), and ceftazidime(0.0%).Conclusions: Detection of CTX-M-producing E. coli in cattle feces raises important questions as they can represent a potential risk factor to public health.

In this work, we have produced biogas by co-digestion of cow dung and slaughterhouse wastewater under different climate temperatures in two countries: N’Djamena in Chad, a country of Central Africa and Dakar in Senegal, a country of West Africa. In a first approach, we put the cow dung in cans of 1.5 L, hermetically closed. The goal was to know how long you could produce biogas. Then we built a bio-digester to produce biogas for cooking. Each bio-digester was exposed to receive solar heat that varied between 27°C to 41°C in Chad and between 24°C to 30°C in Senegal. Influenced by the high temperature and a minimum residence time, the experiments showed that the N’Djamena test produced biogas more quickly than the Dakar test which, on the contrary, had a low temperature and a long residence time. The production of biogas began at the end of seven days with flammability on the twenty-first day for the bio-digester in Chad and after twenty-seven days with a flammability on the thirty-sixth day for the bio-digester of Senegal. The different digestates were valorised in fertilizers, bricks and green coal. Our research aims to meet the living conditions of the rural world specifically for women by reducing their work and thus allowing them to have more time to self-educate and educate their children.

The transport of fattening pigs is characterized by a strong human-animal interaction. Consequent handling is important because of animal welfare, meat quality and matching economic consequences. During road transport, human impact can be divided in different steps: 1) driving pigs from the pens via an alley to the trailer, 2) loading, 3) actual transport, 4) unloading to the lairage, and 5) the final phase driving pigs to the stunning. An inadequate design and a poor condition of the facilities will negatively affect the ease of handling pigs. Because of the consequences, acute stress during transport and slaughter should be minimized by acting on the education of people, on equipment and on preparation of animals for the journey. Education programs have to be repeated regularly so that knowledge can be refreshed.

The conversion of bone waste obtained from meat processing in slaughterhouses is of great significance across the world, with rising concerns about its utilization in developing countries. In Nigeria, for instance, there are fewer successful strategies to transform bone waste into high-value products. While most research papers have concentrated on revealing the environmental, aesthetic, and catastrophic health problems associated with the current slaughterhouse waste disposal in developing countries, this paper presents an engineering approach to managing slaughterhouse solid wastes that majorly consist of bones and horns. A medium-size bone milling machine was designed and fabricated with well-detailed design principles to make it reproducible in any industrial capacity. 3D modeling and simulation were employed to evaluate the machine design and performance. Static simulations performed show that the machine can withstand values of 219.313 kPa, 12.7 exp 7 MPa and 2182.5 Nm for the shaft bending moment, hammer pressure, and output torque, respectively. The machine is 98% efficient on performance evaluation, milling 250 kg of treated sun-dried cow bones in an average time of 10 min 2 sec. This paper also recommends workable means for the installation and utilization of the bone milling machine in slaughterhouses across Nigeria.

slaughterhouses generate considerable quantities of wastewater due to the huge amount of blood produced from slaughtering process and the need for cleaning and hygiene of meat. Due to the extraordinary content of organics and minerals, wastewater from slaughterhouses needs special care and treatment for safe disposal to the environment. Currently, wastewater from slaughterhouses in the Gaza Strip is discharged to the public networks without any treatment burdened central wastewater treatment plant, where partially treated effluent discharged to the sea. The aim of this research is to characterize the wastewater from Gaza slaughterhouse to identify the best approach for treatment. Samples from the slaughterhouse were collected during working hours and analysed for physical and chemical parameters. The pH, EC, DO, BOD, TSS, COD, Ammonia Nitrogen and TKN account for 7.1, 3300 μsm, 1.95, 2350, 3500, 4502, 30 and 154 mg/l, respectively. Wastewater from Gaza city slaughterhouse is within the range in comparison to other wastewater from slaughterhouses all over the world.

This article presents a study of Life Cycle Assessment (LCA) at a slaughterhouse located in north-western Mexico with the purpose of testing the premise of a low degree of institutionalization of Industrial Ecology in Mexico. The article aims at analyzing the current role played by the Mexican academia in increasing the degree of institutionalization of the concept of LCA in northwestern Mexico. There was conducted a life cycle analysis study according to the standards ISO 14040: 2006, NMX-SAA-14040-IMNC-2008NOM in a Federally Inspected Type (TIF by Spanish acronym) slaughterhouse in the state of Sonora in Northwest Mexico. The slaughter process was characterized by observing the production tasks during several walkthroughs the production lines and by having short interviews with workers, supervisors, and the manager. The CH4 emissions were calculated using the guidelines suggested by the Intergovernmental Panel on Climate Change (IPCC 2006). The present LCA case study revealed opportunities for improving the environmental performance of the slaughterhouse by taking measures such as the reduction of CH4 from enteric fermentation since methane was one of the main greenhouse gases responsible for climate change. Although, the LCA generated reliable information in terms of climate change or water eutrophication, the chances of implementing sustainable initiatives were unlikely because the benefits to reduce the impacts to climate change or to reduce the water crisis would be unnoticeable and unaffordable for companies. Findings in this study also confirmed the importance of Mexican universities for promoting and conducting more LCA studies among private and public organizations in order to guide firms towards this tool. The case study here presented gives insights to LCA stakeholders in Mexico to implement or improve the effectiveness of their potential LCA initiatives through the identification of strategies, opportunities, and barriers.
