Legislation exists which prescribes specific waste disposal methods, especially for condemned products, but financial constraints prohibits its implementation. Current legislation requires independent meat inspection but it is not yet applied at all abattoirs and will take a considerable period of time before it is in place. Meat inspection does not serve any pwpose if condemned products returns to the food chain. Waste management practices at the different grades of abattoirs (Grades A to E) will be assessed and interviews with management will be used to predict the associated health risks to the community and the meat industry. Results obtained, will be used to construct a model to recommend the most suitable waste management system for each grade of abattoir in the Free State Province. This model would be appropriate for other provinces in South Africa. Spoilage bacteria and pathogenic bacteria are found on the surfaces of meat products. Pathogenic bacteria can cause illness when these products are consumed (Aberle, et.al., 2001). Food borne illnesses are a world-wide phenomena that also play a role in South Africa. Duse (2002) quoted the Department of Health statistics indicating that in the period of January to June 1998 there were 110 cases of food poisoning and 3 deaths and in 1999 127 cases reported and 0 deaths occurred. A large variety of bacterial genera have been recovered from red-meat, poultry and their products for example, Actinobacter, Aeromonas, Pseudomonas, Aalmonella, Zersinia, and Streptococcus. An increase in amounts ofwaste are generated all over the world. Abattoirs are one of the industries that contribute to the problem of possible food-borne diseases and potential health hazards associated with food, especially meat (Bradshaw, et.al. 1992). Waste generated by abattoirs include condemned organs and carcasses, blood, hides, paunch content and carcass trimmings. Condemned products and carcasses, unsuitable for human consumption, are eaten by ,,cavengers" or persons living off refuse sites, and could cause a significant health problem which could lead to disease and death.Current economic conditions force under- privileged communities to seek any possible source of food and some of the sites frequented are landfill sites, dumping grounds and disposal sites used by abattoirs (Personal communication, Derbyshire, 2003),

Confinement is the predominant method of producing poultry and eggs for consumption in the US. Because of its high-density approach, the potential health threats regarding pathogenesis in animals and humans have raised concerns. Although there best management practices exist to control the persistence and proliferation of pathogenic bacteria in poultry houses, very little is known about the bacterial communities, and poultry houses are potential pathogen sinks. We assessed the contribution of industrial poultry production to the structure and composition of bacterial communities in the soils at a poultry production site. Soil samples were collected from under poultry housing areas, litter storage areas, and an accompanying pasture adjacent to the production area; and environmental DNA was extracted from the samples. Following validation and amplification, DNA was sequenced using bacterial-tag encoded pyrosequencing. Bioinformatics analysis showed that the bacterial communities in the soils showed no significant differences in species richness according to observed and estimated operational taxonomic units (Chao1 and rarefaction). Proteobacteria were the major phyla present in all samples ranging from 37.1% in the soils under poultry houses to 53.4% of the sequences identified under pasture soils. Significant shifts in specific taxa were observed, including drops in the abundance of Acidobacteria observed from the poultry house to litter storage soils ( P < 0.05) α-Proteobacteria increased from poultry house soil (10.9%) to pasture soils (32.8%, P < 0.01) and soils under litter storage (22.3%, P < 0.05). The phyla Bacteroidetes, which were observed between poultry house and pasture soils, dropped significantly from 21.8% to 7.2% ( P < 0.05). Clustering exhibited a closer relationship between the soils under pasture and litter storage, while those under the poultry houses were unique. Pathogenic genera were also found in greater abundance under the poultry houses, which raises the question of persistence and re-colonization of bedding material even in the presence of mitigation attempts.

Waste Management Practices

A major limitation to improved waste management in South Africa lies in the paucity of reliable waste data and the exclusion of the contribution of the informal sector from reporting. Due to the disparity in the provision of formal waste management services across households in South Africa, omission of the quantified contribution of informal management practices leads to an inaccurate representation of waste management practices in existing waste data repositories. Given the potentially adverse social and environmental consequences of unregulated waste management practices, a lack of representation thereof has the potential to underestimate impacts. As of 2015, 31% of households are reported as lacking a basic refuse removal service; however, this number cannot necessarily be applied directly to waste quantities, given the regional and socio-economic differences that occur in per capita waste generation rates. The total quantity of domestic waste in South Africa and fraction disposed informally are estimated here, taking into account differences in waste generation rates based on income and settlement type. The characterisation and quantification of unregulated waste streams is beneficial in assessing the magnitude of the problem and, where necessary, identifying mitigation action. The results obtained show that 29% (3.67 million tonnes per annum) of domestic waste generated is not collected or treated via formal management options. Of this waste, the majority (85%) is generated in rural areas. The most common waste management option for unserviced households is a private dump. An estimated 94% of households in unserviced rural areas make use of private dumps, while in unserviced urban and metro areas this decreases to 74% and 71% of households, respectively. Illegal dumping is the next most common waste management option for unserviced areas. The proportion of household waste disposed of via illegal dumping ranges from an estimated 5% for unserviced rural households to 27% in metro areas with the balance made up by ‘other’ disposal/treatment options.

Waste Management Practices

Households and businesses are generating unprecedented levels of electrical and electronic wastes (e-waste), fueled by modernisation and rapid obsolescence. While the challenges imposed by e-waste are similar everywhere in the world, disparities in progress to deal with it exists; with developing nations such as South Africa lagging. The increase in e-waste generation increases the need to formulate strategies to manage it. This paper presents an overview of e-waste management on a global and South African scenarios with a specific case for Cathode Ray Tube (CRT) waste management practices in South Africa. CRTs present the biggest problem for recyclers and policy makers because they contain hazardous elements such as lead and antimony. Common disposal practices have been either landfilling or incineration. The research into the South African practices with regards to CRT waste management showed that there is still more to be done to effectively manage this waste stream. This is despite clear waste regulatory frameworks in the country. However, recent developments have placed e-waste as a priority waste stream, which should lead to intensified efforts in dealing with it. Overall, these efforts should aim to maximise diversion from landfilling and to create value-addition opportunities, leading to social and environmental benefits.

Waste Management Practices

Waste management in rural areas poses a major challenge to local governments in developing countries. Municipalities face limited budgets and obstacles with the collection of waste, as well as a lack of proper equipment, infrastructure, and treatment centres. These obstacles lead to further problems, such as littering and illegal dumping, contributing to the knowledge base regarding remote and rural towns in South Africa. This study aims to assess the waste management practices and challenges of households in a Municipality in the Northern Cape, South Africa. The study investigates the household waste management practices, identifies the challenges experienced by households regarding their waste management, and explores their willingness to participate in a separation-at-source program. A cross-sectional research design was used along with a mixed methods research methodology. A sample of 160 interviews was completed over the period 16 to 20 September 2019. Descriptive statistics and a thematic analysis were used in the data analysis. The results indicate that municipalities, and households, will have to collaboratively search for solutions towards effective waste management in rural areas. Financial constraints also necessitate the investigation of alternative ways of managing household waste through cooperation with surrounding towns.

This study assessed the management practices for controlling porcine cysticercosis (PC) on pig farms and in pork at the slaughter slabs in two counties (Busia and Kakamega) of Western Kenya. A total of 162 pig-rearing households at the farm level, 26 butcher owners, and 26 slaughter slab workers at the slaughter slab level were interviewed using a structured questionnaire. Data were analyzed using the “Statistical Analysis System” (SAS) programme. Results indicated that the frequent management practices used at the farm level (p<0.05) were rearing pigs under free range (69.1%), latrine ownership by households (87.7%), and use of pit latrines (72.8%) in households. At the slaughter level (p<0.05), results of the butcher owners (76.9%) and slaughter slab workers (62.5%) revealed that meat inspection was not practiced adequately in the two areas of study. The results imply that slaughtered pigs for human consumption were not adequately inspected, and thus, the study recommends for implementation of effective pig management practices at the farm level and pork meat inspection at slaughter slabs to prevent PC infections and assure food safety along the pork value chain.

This article investigated the knowledge and practice of a nature-based solution to reduce disaster risks of drought, veld fires and floods using wetlands in the eastern Free State, South Africa. A mixed research method approach was used to collect primary data using three data collection tools, namely questionnaires, interviews and field observations. Ninety-five wetlands under communal and private ownership as well as a few in protected areas were sampled, with their users completing questionnaires. The study showed that communal wetlands were more degraded, while wetlands in protected areas and in private commercial farms were in a good ecological state. An extensive literature review reveals that healthy wetlands are effective buffers in reducing disaster risks such as drought, veld fires and floods which are recurrent in the study area. Therefore, through better land-use and management practices, backed by education and awareness, wetlands could be good instruments to mitigate recurrent natural hazards in the agriculturally dominated eastern Free State in South Africa.

The results of veterinary meat inspection classification of 4&nbsp;000&nbsp;372 bovine carcasses reflect long-term aspects of health status in cattle herds and the quality of transport and handling of animals at slaughterhouses. Veterinary inspectors recorded the data obtained from meat inspection classification of bovine carcasses at slaughterhouses in the CzechRepublicduring the period of 1995&ndash;2002 together with the reasons for classification. The trends were evaluated by a comparison of two periods (Period I, 1995&ndash;1998, and Period II, 1999&ndash;2002) by means of calculating the indexes of values from Period II compared to those of Period I. Bovine carcasses classified as capable for human consumption (edible) were found in 87.87% of cases (88.83% during Period I and 86.58% during Period&nbsp;II, index 0.97), while those classified as capable for processing (conditionally edible) were found in 7.53% of cases (7.38% during Period I and 7.71% during Period II, index 1.04), and those condemned in 4.60% of cases (3.79% during Period I and 5.71% during Period II, index 1.51). The most important reason for classifying the carcasses as condemned was the finding of sensorial changes in meat, which occurred in 2.56% of cases (2.23% during Period I and 3.00% during Period II, index 1.35), followed by lesions due to non-infectious diseases &ndash; 1.00% (0.81% during Period I and 1.25% during Period II, index 1.53), added deleterious substances &ndash; 0.88% (0.60% during Period I and 1.27% during Period II, index 2.11), lesions due to respiratory infections &ndash; 0.03% (0.02% during Period I and 0.04% during Period II, index 1.74), and lesions due to miscellaneous infectious diseases &ndash; 0.10% (0.10% during Period I and 0.10% during Period II, index 1.05). Other reasons to condemn the carcasses included improper identification, lesions due to digestive infections, lesions due to tuberculosis, lesions due to paratuberculosis, lesions due to salmonellosis, leucosis and parasitic diseases. The occurrence of these conditions was on the level of mere hundredths of per cent. According to the results of meat inspection classification, the risk of food-borne diseases originating from bovine carcasses tends to be greater in the lesions due to non-infectious conditions with a long-term increasing trend. A&nbsp;considerable increase in the numbers of bovine carcasses condemned because of lesions due to paratuberculosis (index 4.62) represents an alarming finding with regard to potential food safety hazards.
