Maryland health officials are investigating possible cases of food poisoning at what may be the worst-ever venue — a gathering of government and industry leaders attending a national Food Safety Summit.

At least four people called the Baltimore City Health Department this week to report that they developed diarrhea, nausea and other symptoms about 12 hours after eating a meal April 9 during the conference at the Baltimore Convention Center.
