    ABSTRACT

    Dairy products or milk products are a type of food produced containing the milk of mammals, most commonly cattle, water buffaloes, goats, sheep, and camels. Dairy products include food items such as yogurt, cheese and butter. The aim of the study is to investigate the Bacterial Contamination of Dairy Products and Detection of the Metabolites. In achieving this aim the following specific objectives were considered to; isolate and identify Staphylococcus aureus and Escherichia coli present in Yoghurt, Nono and Madara, determine the most predominant of the above mentioned organisms in Yoghut, Nono and Madara and determine the antimicrobial susceptibility of the above isolated organisms. All samples were inoculated on different bacteriological media and various biochemical tests were performed for the confirmation of isolates. The result of the present study revealed that out of 135 samples, 25 samples were found contaminated with Staphylococcus (14) and E.coli (11). The highest rate of contamination was recorded in Burfi (5) while the lowest was recorded in Ice cream (1). These enteropathogenic bacteria may cause problems due to improper handling and processing of milk and milk products. These organisms are significant from public health point of view as they have been associated with the onset of food poisoning in human beings. Since dairy products are widely consumed as food, this study will help to establish contamination by Staphylococcus aureus and Escherichia coli, mode of contamination and thus aid in determining their safety for consumption. The result of this study will also help in providing information on these products by the producers, which will promote healthier handling of the product by the producers, the sellers and the consumers.

    CHAPTER ONE

    1.1 Introduction

    Dairy products or milk products are a type of food produced from or containing the milk of mammals, most commonly cattle, water buffaloes, goats, sheep, and camels. Dairy products include food items such as yogurt, cheese and butter. A facility that produces dairy products is known as a dairy or dairy factory. Escherichia coli are part of the normal human intestinal flora. E. coli has been studied intensively in genetics and molecular and cell biology because of its availability, its small genome size, its normal lack of pathogenicity (disease-causing ability), and its ease of growth in the laboratory. Staphylococcus aureus is a Gram-positive, round-shaped bacterium, a member of the Firmicutes, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin.

    As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Research Questions and Hypothesis, Scope of work, Limitations of the Study and Definition of technical terms.

    Defense Procedure for Microbiology Researchers

    In preparation for defending a project or seminar on Bacterial Contamination of Dairy Products and Detection of the Metabolites, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

    Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

    Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

    During the question and answer segment, the External Examiner may pose questions pertaining to your research. If confronted with a challenging or irrelevant question, respond diplomatically with, “Sorry, Sir/Madam, the question asked is beyond the scope of my study.” Whenever possible, direct your answers back to your research findings to reinforce your expertise.
