Ryan met his friends at In-N-Out for lunch and ordered a plain double double burger. A few hours later he is not feeling well and thinks he has contracted a food-borne illness. Which one is he most likely to have contracted?

Answer:
E. Coli (Option A)
Explanation:
It's not B. Salmonella is contracted from reptiles, poop, etc. and is unlikely to be found in a regulated restaurant setting.
It's not C. Gastroenteritis isn't really a foodborne illness and has specific, easily identifiable symtoms anyways.
It's not D. Ryan would be dead if he contracted Botulism.
