Have personally witnessed crew incap from food.
FE took approx 10 minutes to go from a healthy (if stunningly unattractive - sorry Mort!!) individual, to a quivering white lump of jelly hurling chunks of the offending snack into the bag.
Fortuantely he recovered fairly quickly after a few good hurls, but the speed at which it overcame him was insane. We had trouble getting the trolly dolly's to visit forthe rest of the sector, wasn't the prettiest smell..... .
