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.

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

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

"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."
Some learners found the mathematical sections of the course to be challenging.
"The MOOC was very informative and helpful to me since I am learning cooking right now. However, it would be good if the MOOC creators check the validity of their links every now and then."
"Very well structured, interesting and covering lots of topics. I would have liked to spend more time on pathogenic bacteria, studying more where they are found and their risks. Covering chemical contaminanats in more details would also be very beneficial."
"it would be good if the MOOC creators check the validity of their links every now and then."
