“…Abattoir is one of the food industries that contribute to the problem of possible food-borne diseases and health hazards associated with food unless the principles of food-borne hygiene practices are implemented [24]. The current study showed that there was no clear division of slaughtering process: stunning, bleeding, skinning, evisceration, hanging, and cutting/deboning.…”

The study was conducted from November 2015 to November 2016 to determine bacterial load and identify pathogenic bacteria (S. aureus,E. coli, andSalmonellaespecies) in meat from abattoir and butcher shops as well as to assess associated hygienic and sanitation practices being experienced in the selected study site. A cross-sectional study was conducted where a simple random sampling method was used to select butcher shops, and the municipal abattoir was purposively selected. A structured questionnaire survey was also used to assess hygienic status of the municipal abattoir and butcher shops. A total of 124 samples (48 swab samples from abattoir carcass, 4 samples of carcass washing water about 20 ml of each, and 36 swab samples each from butcher shop cutting table and cutting knife, respectively) were collected during the study period. The collected samples were processed for aerobic plate count, and the total mean count was found to be 4.53 log10 cfu/cm2from abattoir carcass swab samples, 2.4 log10 cfu/ml from water samples, 6.58 log10 cfu/cm2from butcher shops cutting table, and 6.1 log10 cfu/cm2from cutting knife swab samples.E. coliwas the dominant bacterial species isolated (35.2%), followed byS. aureus(22.5%) andSalmonellaespecies (9.9%). According to the questionnaire survey, 48.4% (15/31) of the abattoir workers did not receive any training regarding food safety issues. Moreover, a majority (66.67%) of the respondents of the butcher house workers were grade 1–4 (elementary) in their educational level and do not use hairnet and handle money with bare hands during serving meat to consumers. The study showed that the hygienic status of the abattoir and butcher shops in the study area is poor, and the obtained results of bacterial load are higher than the acceptable limit of the standard. Therefore, the necessary strategies towards hygiene and sanitation of meat in the town should be implemented.

“…Approximately 50-54% of each cow, 52% of each sheep or goat, 60-62% of each pig, 68-72% of each chicken, and 78% of each turkey end up as meat consumed by human beings with the remainder becoming waste after processing [7]. Moreover, of abattoir waste, the volume of wastewater from abattoirs is 70-75% of the abattoir water that contributes to a high organic load as well as a considerable amount of suspended material in the waste [8].…”

Our environment is facing serious problems of high volumes of waste generation and inadequate disposal system in worldwide particularly in developing countries. There is also lack of studies on quantification of abattoir waste and lack of workers awareness towards abattoir waste. Therefore, the purpose of the study was to estimate abattoir waste for bioenergy potential as sustainable management. A cross-sectional study was conducted in four selected abattoirs of Eastern Ethiopia from January 1st, 2018 to December 30th, 2018. The magnitude of abattoir waste composition was computed based on Aniebo mathematical computational from the actual number of slaughtered livestock. The study demonstrated that four selected abattoirs generate 1,606.403 ton of abattoir waste per year and using anaerobic digestion of about 85,139 m3/year of biogas and 111.25 ton/year of biofertilizer can be produced. The biogas or energy from the waste can replace firewood and charcoal and the expensive fossil fuels. Using Banks mathematical computation about 20,054.12 m3/year production of biogas could replace 20.56 ton/year of energy consumed by liquefied petroleum gas, kerosene, charcoal, furnace oil, petrol, and diesel in average. The current estimated biofertilizer (111.25 ton/year) from four abattoir sites can cover about 2,225 hectares/year with its advantage and efficiency of soil. When turned into cost, about $55,645 per year of price could estimate from biogas and biofertilizer. The study concluded that huge amount of biogas and dry biofertilizer yields could produce from abattoir waste through anaerobic digestion. Therefore, installing anaerobic digestion plant is recommended to ensure environmental safety and public health.

“…In this study there was significant association between abattoir effluents and diseases affecting abattoir neighbouring community (Table 3 and 4). According to [7] reported that abattoir effluents contain a lot of disease causing organisms. Similarly medical expert were reported to have associated some diseases with abattoir activities which include: pneumonia, diarrhoea, typhoid fever, asthma, wool sorter diseases, respiratory and chest diseases [1].…”

Poor management of abattoirs results in air and water pollution especially resident’s in their close proximity. The objevtive of the study was to investigate the effect of poor management of abattoirs on the quality of life and health of residents in their vicinity. A cross sectional survey was conducted within two month period. Fifty six residents of buildings located approximately five kilometers radius to the abattoir were randomly selected for interview using questionnaire. Among the 56 residents interviewed, 20 (35.7%) were sicked. Almost half (33.9%) of the residents suspected the sickness to be related to abattoir hazards. The prevalence of diseases and symptoms experianced by the residents were typhoid fever (14.4%), Diarhoea (12.5%), Coughing (10.7%), Asthma (8.9%), Foot and Mouth Disease (7.1%) and Dengue (3.6%). The main associated factors of abattoir activities on residents ‘s health were contamination of air with pollutants (odds ratio,15.52; 95% confidence interval, 3.62-10.52), water contamination (11.44; 3.17, 12.28), gutters and drainages blockage (6.35; 1.26, 9.99) and prevention of children from outdoor activities (4.65; 1.33, 16.31). There was also reported case of food poisoning among the residents. Abattoir activities has direct and indirect negative effect on residents health who are in close proximity.
