Overview

Everyday reports of food scandals and recalls are published. One day it's scary bacteria in meat, and another day it's dangerous pesticides in fruits. According to some, meat needs to be cooked well to prevent food-borne illness while others warn not to heat food to prevent the formation of poisonous substances.

Many consumers worry about the conflicting and confusing messages about food hazards

This nutrition and health course will teach you about the hazards associated with food and give you the tools to assess and quantify the dangers they can present. You will learn the effects of food processing, the shared responsibility in the food chain and the prevention of food poisoning/intoxication. After this course, you will be able to differentiate what is a food myth vs. an actual risk. Finally, you will gain a contemporary view of how different risks can be weighed in a scientific way.

Syllabus

Module1: Hazards and risks in the modern food chain
Introduction to the difference between a hazard and a risk, the different types of hazards present in food and the perception of risk by public.

Since I was auditing the course I found some of the science and math difficult to follow in the time I desired to spend on the course. I did learn a lot of helpful things that I have already put to use in determining the purchase and use of a new food product. I felt the course was well organized and the speakers were informative. As with health care and taking medications there are a lot of risks the consumer must consider before deciding on consuming foods. We assume everything that is sold to the public is totally safe, which is not true. Learned many good tips on the selection, storage, and preparation of food products. Thank you.

The course is very interesting although it presents many technical topics not immediately understood. It would be useful to have a synthetic pantry that summarizes the various methodologies and procedures in risk assessment

The presenters and course coordinators have taken care to develop an interesting program. The videos and links to extra material are interesting and informative. I expected the course to be based on microbiology, nutrition and the health aspects of food risks but not the actual calculation of "MOE", "EDI" "DALYS" etc, and it would have been interesting to study more actual disease outbreaks in detail. At times English expression was a little difficult to understand, requiring further research and rewriting of the text for my personal records. Looking back through the course notes I realised I have learned new information, been challenged and have gained new skills. Though, as I have retired I probably will not select the certificate stream again if I attempt another MOOC.

The course is very well constructed. The information is well presented by the staff and the interactive materials are good. The commitment of the staffing team and presenters make the course more interesting and engaging, and encourage participants to explore more knowledge on related topics. The info learned from this course has been very useful in improving food safety in our daily life, our family food hygiene and useful info to be shared with friends so that more people are aware of food safety and do better together to achieve a safe social environment with less food risks and hazards. This is a great course for everybody.

This course is very useful. The topics are highly appropriate when considering the course topic. The teaching staff is very talented and the way of teaching is very attractive. Videos, audios are also in very good quality. Because of the great explanations about the lessons, easy to understated. Food Myth was a attractive lesson. At the end of the course I was able to collect lot of new information with related to the food safety. This course can be followed without any boring. As a student who has completed this course, I highly recommend this course for any on who is interested with food safety.

I just recently finished this course, without taking the exams and assignments as I am only using the audit access and here are my thoughts:

- The MOOC is easy to understand, well-explained, and precise.

- It is very useful and essential as it is aligned to my subject regarding food safety and microbiology in my nutrition program.

- All videos are very nice. It feels like you are taking a classroom lecture virtually.

- Lastly, I really enjoyed the experience of using an online course as it is the first time that I have been completed.

Keep up the great content! :D

As an agro-industrial engineer in Colombia food security is important, as a social work, I have loved this course, I have learned totally new topics which are satisfactory for me, I would like my university to give all these topics, I would like to do a Master in Wageningen about these topics, I would recommend all my friends in the university career to do the course and to travel to Holland to do the Master if possible, I am sure that my next step will be that.

I think this MOOC is well done, it provides you with a lot of info regarding different subjects. I would have appreciated more to have the chance to download more full articles (some of the additional material links are pay per view access). Also more examples would help understand some argouments (like different practical cases in which responsibility is exerted by different actors in the food chain).

Anyway, overall I think it's worth taking this course!

Enjoy the course, very thorough in covering various related topics. The professors make an effort to make the videos interesting and engaging. They add live examples, and the myth of the week is also interesting. The background of the video is also carefully chosen to adapt to the topics, and to be engaging with the students. Exercises and problems after the lessons are helpful in refreshing the knowledge learnt.

I like little tests at the end of the modules, to check yourself and to correct yourself (thanks to the detailed answers). Great job of the everybody, involved in the course to present everything so interesting i funny. It was a pleasure :)

I enjoyed this course and have learnt a lot. As what your term "from farm to fork", how each stakeholder is responsible for food safetly. There are quite some abbreviation and maths knowledge would be required. If it is a challenge for you, you can still skip those questions and still enjoy the rest. It is worth to know that there is no 100% food safety. But we can help to minimize the risk.

It is a course that is not only interesting but also easy to understand and follow. The course has not only widen my knowledge about what I have been doing wrong in terms of food safety but has also provided me with the proper ways to keep food safe. It has also cleared a lot of the myths and doubts that I had. I have learnt a lot and applied what I learnt throughout the weeks in my daily life. Thank you!

This is the best food risks class i have attended. it has given more insight of different food risks, how to calculate risk, chemical threshold, types of microorganisms, allowable limits food, food spoilers, food temperature that prevents and promotes microorganisms. All these topics have changed my views on food risks and safety and this help me in implementing in my course of study.

it was an interesting module that I took to increase my knowledge about nutrition and food safety. I think that the content taught was very useful in everyday life, and I now know how to handle food more carefully without introducing pathogen or bacteria. I would encourage many people to take this course too as it can prevent food illnesses and food poisoning
