FOOD MICROBIOLOGY - 2023/4

Module code: BMS2041

Module Overview

The aim of the module is to give the students an understanding of the microbiota of food through a series of lectures, tutorials and related practicals, with a particular emphasis on bacteria and their key role in food fermentation, preservation, spoilage and foodborne illnesses. We will also demonstrate that bacteria are naturally present in food that derives from animals (fish, milk and meat) and the environment (honey). The concept of gut microbiome will be covered, and we will describe the implementation of control measures in food industry to mitigate the impact of bacterial pathogens. In addition, the module comprises statistical analysis, guided learning hours and captured content; and the assessments form an essential part of the Food Science & Nutrition and Veterinary Biosciences degrees. It is also highly recommended to students doing Microbiology.

Assessment pattern

Assessment type Unit of assessment Weighting
Coursework LAB NOTEBOOK (LAB REPORT AND SHORT QAS) 50
Examination Online ONLINE (OPEN BOOK) SAQ EXAM - 120MINS WITHIN A 4HR WINDOW 50

Alternative Assessment

Alternative assessment for 'LAB NOTEBOOK (LAB REPORT AND SHORT QAS)' is 'written coursework to assess the underlying principles of the appropriate learning outcomes. These will reflect the material covered in the original assessment'

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their understanding of the practical techniques used in the microbiological examination of foods and their knowledge in key areas of food microbiology.

Thus, the summative assessment for this module consists of a:


  • Lab notebook, 50%, comprising a lab report and short answer-questions (Learning objectives 1, 4)

  • 2h Short Answer Question (SAQ) exam, 50% (Learning objectives 2, 3, 5, 6)



Formative assessment

There is an optional “lab report” to submit from which students will receive formative feedback on the lab notebook. Tutorials will help students combine the theory with the practicals, and they will be assisted with data analysis and interpretation. Short tests and quizzes will also be used to assess the students’ progress throughout the module, with a final revision session on the last week of the semester.

Feedback

Students will receive extensive written and verbal feedback on their practical write-ups and verbal feedback on their short tests/quizzes and during the tutorials or revision session.

Module aims

  • To outline the different microbiology naturally found in food and show that they may lead to desirable (fermentation, probiotics) or undesirable (spoilage, disease) effects.
  • To describe the physico-chemical factors influencing microbial growth and survival in foods and how they can be used as control measures.
  • To compare the physico-chemical properties of a selection of food commodities and their influence on the microbiota associated with them.
  • To introduce the basic and advanced practical techniques used in the microbiological examination of foods, including modern preservation methods for assuring the microbiological quality of foods.
  • To emphasise and illustrate the varied roles of microorganisms in foodborne illness, food spoilage and food fermentation.
  • To describe the basic epidemiology of foodborne illness and the key features of the most common causative organisms.

Methods of Teaching / Learning

The learning and teaching strategy is designed to give the students an understanding of the origin of the food microbiota and the key roles that bacteria play in various food commodities, with further implications in animal & human health. Students will also be equipped with key technical skills in the area of food microbiology.

The learning and teaching methods include:


  • Lectures 

  • Practicals

  • Tutorials

  • Guided Learning and Captured Content 

  • Independent study 



 

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
