Assessment Scenario: Outbreak Case Study

Read through the two outbreak case studies given below and produce a report in which

you should discuss each outbreak considering the following points:

1. What organism do you suspect has caused the outbreak and why? In your report

you should consider the incubation period, what symptoms were reported, the

foods involved and groups of population affected? Any other useful information of

relevance. Note there may be more than one probable cause in some cases. Why

have you ruled out certain organisms?

2. Which food is likely to be the source and why? You should consider the type of food

and features of the suspected organism that make this food a more likely source.

Why have you ruled out other foods?

3. Would you suggest treatment in the case situation? How would you use laboratory

testing to determine the most appropriate antimicrobial to use?

4. If you feel that more than one organism could cause the symptoms described,

explain what tests would you perform to confirm the identity of the causative agent

and why?

5. What detailed (not general) advice would you provide to the food handlers to

prevent this type of outbreak from happening again?
