Development of a Rapid Detection Method for Foodborne Pathogens in Fresh Produce Using Molecular Techniques

Thesis Abstract

Abstract
The presence of foodborne pathogens in fresh produce poses a significant threat to public health and food safety. Traditional detection methods are time-consuming and labor-intensive, leading to delays in identifying contamination outbreaks. Therefore, there is a critical need to develop a rapid and efficient detection method for foodborne pathogens in fresh produce. This thesis aims to address this need by developing a novel detection method using molecular techniques. Chapter One provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter Two presents a comprehensive literature review covering ten key aspects related to foodborne pathogens, detection methods, molecular techniques, and relevant studies in the field. In Chapter Three, the research methodology is detailed, outlining the experimental design, sample collection, DNA extraction, PCR amplification, sequencing, data analysis, and validation procedures. The chapter also discusses the selection of target pathogens, primer design, and optimization of PCR conditions for maximum sensitivity and specificity. Chapter Four presents a detailed discussion of the findings obtained from the developed rapid detection method. The chapter includes the validation results, comparison with traditional methods, detection limits, accuracy, precision, and practical implications of the novel technique. The findings are interpreted in the context of existing literature and potential applications in the food industry. Finally, Chapter Five provides a conclusion and summary of the thesis, highlighting the key findings, implications for food safety, limitations of the study, future research directions, and recommendations for implementing the rapid detection method in practice. Overall, this thesis contributes to the advancement of food technology by introducing a reliable and efficient method for detecting foodborne pathogens in fresh produce, thereby enhancing food safety and public health.
