Nicholas C. Stern of the Fredrick News Post reported that the Frederick County Health Department has concluded its investigation of salmonella infantis infections linked to food eaten at a March 5 benefit pancake breakfast at Trinity United Church of Christ in Thurmont, according to Dr. Barbara Brookmyer, county health officer.

Eighteen cases of infection were reported, nine of which are considered confirmed by stool sample testing and based on symptoms developed. Nine are probable because some people reported symptoms consistent with salmonella, but no stool samples were taken, Brookmyer said in an email.

No deaths were reported. All of those hospitalized have been treated and released, she said.

The infections were linked to sausage and meat pudding consumed at the benefit breakfast, Brookmyer said.

The meat products were originally from a Frederick County 4-H Camp and Activities Center butchering event held Jan. 27 at the Mount Pleasant Ruritan Club.

The camp center is a nonprofit not directly affiliated with the 4-H youth development group, 4-H Extension Educator Mike Kuster said.
