Foodborne illness

Case Study #5No one word answers please

A 19-year old male college student arrives at the common area of the dorm after missing a test. He sees
his friend with a very small glass of water. He says “dude, you look like crap” He explains he awoke the day before at 11:30PM with vomiting and diarrhea, he tells his friend ” I was on the freaking toilet with a
garbage can between my legs what felt like Satan flowing out the other end.” His friend says he was in the same way at about the same time. This glass of water is the only thing he has kept down in 24
hours. They had both eaten ham sandwiches from the dorm cafeteria at 10:30PM before hitting bed at 11:00PM. They both noted the sandwich was at room temperature and were left from dinner at
6:00PM.

1) Foodborne illness if a pretty safe diagnosis here, based on the above do you think this is an infection or an intoxication? Why?

2) Name some of the more common species that form toxins.

3) Other than a missed test and a 7 lb overnight weight loss will the students have any lasting
problems? Other than eating more room temperature meats in the cafeteria will this probably be fully resolved in 24 hours?

4) Assume this was a S. aureus intoxication, where do you think the staph came from?
