  7. Explore 2

  8. Contamination Sources of Contamination Worker hygiene Melted fat and juices Coughs and sneezes Mishandling of foods

  9. Contamination Testing for Contamination • A bioassayis a test to determine the strength or activity of a substance. • Two types: • Quantal: gives a definitive “all or none” result • Graded: response is proportional to the input

  10. Learning About Pathogens Launch Student Module

  11. Pathogen Detectives In a small group, you will investigate one type of pathogen. Here are the things you need to find out: Detailed information about the pathogen How the pathogen impacts food safety along the farm-to-table continuum How to control the spread of the pathogen More detail about how different types of bioassays work

  12. Explain 3

  13. Presentation Here are some tips for giving a good presentation about your pathogen: Identify the assigned pathogen. Explain how foods can be contaminated by the pathogen. Describe the illness(es) that can result if humans eat food contaminated by the pathogen. Explain how bioassays can be used to identify the pathogen. Share any other interesting facts from your research.

  14. Extend 4

  15. Compare and Contrast Think about the pathogens that have been discussed. What are the similarities and differences? What foods are most often contaminated by each pathogen? Which symptoms caused by the pathogens are similar? Which are different? Do the pathogens affect people differently? For example, is one pathogen more dangerous to infants or the elderly? What are the existing methods of food analysis and detection for each pathogen?

  16. Extend 5

  17. Current Events: Assignment Research a recent incident of food contamination, then write a summary of what you learn. Focus on the following questions: What happened? How did the contamination occur? What pathogen was involved? How was the contamination detected? How was the situation resolved?

  18. Current Events: Rubric Information Covered Possible Points • What happened? • How did the contamination occur? • What pathogen was involved? • How was the contamination detected? • How was the situation resolved? 20 20 20 20 20
