Dissertation submitted in fulfilment of the requirements for the degree Master of Technology: Environmental Health in the Faculty of Applied Sciences at the Cape Peninsula University of Technology, 2011<br>The retail sector in South Africa is increasingly evolving into a dynamic industry, driven by changes in technology, saturating markets and globalisation. A major phenomenon in South Africa has been the evolution of hypermarkets, which sell large quantities of almost all consumer goods on a self-service basis. The South African consumers are becoming increasingly health conscious and, as suc

A poluição, alteração física do habitat e a introdução de espécies invasoras via água de lastro, representam os maiores impactos antropogênicos para os ambientes costeiros. Foram pesquisadas em amostras da região costeira de S. Paulo, regiões portuárias brasileiras e de tanques de lastro de navios, bactérias das espécies Vibrio cholerae (Vc), V. parahaemolyticus (Vp) e V. vulnificus (Vv) que são as que têm maior implicação na saúde pública. As amostras foram avaliadas levando-se em conta parâmetros físico-químicos e microbiológicos e suas relações com a presença de Vc, Vp e Vv. As relações cl

Abstract:

This thesis deals with the Air to Ground Heat Exchangers (AGHEx) and their effects on the hygienic quality of the supplied air and the microbial microclimate in the interior of buildings. The theoretical part focuses on current findings and knowledge in the field of warm air heating, ventilation of the low-energy and energy passive houses and ground heat exchanger for the ventilation systems to family houses. The next chapter deals with the quality of the indoor environment and the influence on HVAC systems on the building microclimate. The experimental part of the thesis presents the results

Abstract:

Diarrhoeal diseases remain a main cause of preventable death, particularly among children under five years of age in developing countries. In addition, many studies related to infant diarrhoea causation have demonstrated that the level of contamination is higher in weaning foods than in drinking water. Furthermore, many studies addressed food microbiological contamination and its role in diarrhoea causation. But few of them resulted in an intervention. Although the Hazard Analysis, Critical Control Point (HACCP) approach has been developed and widely applied to food promotion in industrialised

Abstract:

Filamentous moulds may cause spoilage in raw materials, foods and feeds. Some of them synthesize mycotoxins which are a risk for human and animal health. For this reason, from the food safety point of view, only mycotoxins, as chemical hazards, are important. Nevertheless, despite the absence of direct correlation between mould growth and mycotoxins production, the prevention of fungal growth in raw materials and foods leads invariably to the prevention of mycotoxins presence. Due to the fact that moulds can contaminate foods from raw materials till end products, different strategies could be

Abstract:

Foodborne illnesses place a burden on the entire society. One strategy to lower the costs of foodborne illnesses is to reduce the prevalence of foodborne pathogens through interventions along the food supply chain. There is an ongoing trend that food safety systems are moving towards performance-based regimes, which rely on the implementation of food safety standards. However, the implementation of food safety standards has not garnered much interest in the Canadian policy environment. The assessment of food safety interventions to achieve a standard is challenging as the underlying biological

Abstract:

In many countries, the authorities face extreme difficulties in monitoring and ensuring that food sold on the street is safe, that is, fit for human consumption. This is particularly the case in urban areas, where people buy food on the street because it is readily available and relatively inexpensive. The objective of this study was to determine the food safety knowledge and microbial hazard awareness of street food consumers, and to assess the bacteriological quality of selected ready-to-eat foods sold by street vendors in the Johannesburg municipality.

"Salpicão de Vinhais" and "Chouriça de Vinhais" are traditional dry-fermented smoked meat sausages produced in Vinhais, a small region of Trás-os-Montes. The scientific knowledge of this sausage variety is limited. This work aims to collect scientific data that could, partially, fill the gaps in knowledge regarding these products, analyse the data and develop a risk-based study, according to an internationally accepted framework and finally, to explore the effect of hypothetical risk management measures on the safety of consumers, regarding traditional dry fermented meat smoked sausages.

Abstract:

In the following study, the potential role that microorganisms play in the removal of Mn (II) and Fe (II) was assessed using biofilter sand and water samples collected from a biofiltration system (operated by Umgeni Water in KwaZulu-Natal, Nottingham Road, at the Nottingham combined school, South Africa) treating borehole water containing manganese and iron. Initially the presence of Mn (II) and Fe (II) oxidizing bacteria was demonstrated in the biofiltration system. Thereafter, the contribution of individual microorganisms to the overall removal of manganese and iron was assessed in the labor
