About the content

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 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.

  • Overview of food hazards
  • Elementary knowledge on microbiological and toxicological risk analysis
  • How to better interpret the information overload about hazards in food
  • Why zero hazard does not exist
  • Ways to reduce hazards in food

Wageningen University

Wageningue University is located in Wageningue, the Netherlands. Its campus is located on the outskirts of the city, which allows it to plan numerous extensions to its premises, all of which are already ultra-modern, due to its scientific nature. The university focuses on life sciences, sociology, business relations and natural resources.

In particular, the University is home to the Alterra Institute for multidisciplinary research into the artificial and man-made environment (rural environment, urban ecology, green spaces, green webs).
