  • Students will learn the basics of food safety and develop an introductory understanding of the 4 types of fish poisoning that we will cover. By the end of the course, learners should be able to tell someone who has no knowledge of these poisonings/toxins the basics as they pertain to fish ingestion.
While completing my MPH, I spent a great deal of time creating content on food safety, food poisoning and obscure diseases.  My undergraduate studies in biology gave me a firm foundation in microbiology and the chemistry involved in food spoilage.
Homework Offered
There will be one short assessment per week that covers the slideshows and readings; each is 10 questions or less. There will also be 2 small projects assigned. The learner will need to do independent research online, and I anticipate homework taking 1-2 hours a week.
0 - 1 hours per week outside of class
Assessments Offered
I will correct assessment answers, but will not give letter grades. All assessments are 10 questions or less. I will read the projects and assignments, and provide feedback when warranted.
Grades Offered
Assessments, instructions, articles and paragraphs will be uploaded directly to the classroom.  Learners will not need to print them unless that makes it easier for them.  Assessments can be turned in as answers (instead of filling in the Word documents).
In addition to the Outschool classroom, this class uses:
This course does cover food poisonings, some of which may be serious.  Projects will need internet research to complete (they will need to research food safety and find case studies to report on); make sure your learner has knowledge of internet safety. 
I will show a brief clip of “Histamine - The Stuff Allergies are Made Of” during week one.  Here is the link to the entire video.  

The following is an assigned reading.  Learners will not need to visit the website itself as it will be saved as a PFD and posted, but they will need to be able to open the PDF.
