(AP) AMSTERDAM - Was it the fish?
An estimated 230 University of Amsterdam professors or their spouses got violently ill last week after the school’s annual faculty party. Spokesman Joost van Tilburg said food poisoning was believed to be the cause.
He says the professors’ distress "mostly involved stomach problems."
Some 400 people attended the party.
The results of an investigation by health authorities are due Thursday.
