Read through the three outbreak case studies given below and produce a report in which you should discuss each outbreak considering the following points:

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?

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?

What detailed (not general) advice would you provide to the food handlers to prevent this type of outbreak from happening again?

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?
