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.

Module 2: Interpretation of risks, probability and relevance
Introduction to risk reporting, how ways of presenting information can mislead consumers and difference between significance and relevance.

Module 3: Microorganisms in food: good, bad and/or a nuisance
Introduction to ubiquitous, good/bad or spoiling microorganisms.

Module4: Qualitative and quantitative principles food safety of chemicals
Classification of risks as avoidable or unavoidable, difference between genotoxic and non-genotoxic compounds and examples of important genotoxic carcinogens present in the food chain as well as introduction to dose-response concept.

Module 5: Toxicological risk assessment
Introduction to risk assessment framework, different ways of performing risk assessments depending on the nature of the chemical (i.e. genotoxic vs. non genotoxic) and hands on risk assessment of the food additive cyclamate and the carcinogen acrylamide.

Module 6: Microbiological risk assessment
Introduction to contamination routes, dose-response relationship and effect of temperature on microorganisms' growth as well as sampling and legal requirements.

Module 7: Ways to reduce risks in food
Introduction to prevention of avoidable hazard, effect of heat on hazards and inactivation as well as prevention techniques to reduce risks in food.

Module 8: Final assignment/exam
Wrap-up.

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.

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

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!

Great course! Very detailed with a lot of information, including additional and helpful links and data, explained in a comprehensible way with videos, graphs. 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 joined this course to get answers to some questions I had, and the course did a very good job of answering them (the description of the course is very accurate).

I also think a lot of effort went into creating this course, and that effort was definitely appreciated! It resulted in an enjoyable and educational experience.

Thank you to everyone who participated in the creation of the course!

This course has a lot of things to teach you about food risks but also in what way you are involved in the food chain. Im glad to join this course. One thing that I would like to be improved is the chapter 'Myth of the week'. I think there are much more myths and misleading about food and its contaminant, and it is necessary to be clear through this course.

The MOOC is covering all parts and the ABCD's required for a passionate learner and especially the bigginers in Food Science/Technology. Teachers are formidable and have given exemplary embodiments to the course.

I hope in future the Wageningen University offers more such platforms of learning for a reformation and add a lot of value and essence to it.

it does give a lot of insights as to how much processes goes behind the food supply chain and how we as consumers can play a part in enhancing and improving food safety. it allows us to make daily food risk assessment when consuming food on a daily basis and attempts to reduce the hazards exposed to our body so as to lower risks presented to us

Nicely done and structured. Easy to follow with nice excercises to repeat learned stuff. The teachers are also very nice and do a great job. You have lots of possibilities to take part and get in touch with others by discussion and by polls asking about your opinion (e.g. myth of the week --> really cool idea ;) )

I think the course is very good, it has valuable and quality information, I think that the teachers are very qualified, so the material meets the expectations, I just think that the calculations part needs to be improved, in which you have to delve a little more so that it is fully clear how they are carried out

It was my second time taking this course, because the last time, for a “time problem” with the MOOC ending and my final project deliver time was kinda’ confusing; but I guess it was just good, because I could solve my questions and finally it was crystal clear. Thanks.

This time I’ve enjoyed the most. Thanks.

The exercises were kind of hard to get right. When we were asked to use the thermal inactivation tool for example, I had a hard time figuring out how to use it, because I thought I did but I wouldn't get the answers right. Other than that is a good course, it refreshened my knowledge.

It is a great course to take even if you do not have any professional relationship to food. It provides great information regarding how we as consumers can protect ourselves in our own kitchens. It also clarified to me why there are so many different opinions on food safety

the course provides useful information and websites about food safety. After completing the course, I have more cognition about food safety, microorganism, bacteria and virus and keep good practices on hygiene, food contamination, storage, cooking and cleaning...

Thankyou so much for improving my knowledge about this subject! It will help me at my job. Because this Mooc really helped me I decided to also start with "overnutrition and malnutrition" in February this year.
