The News-Post of Frederick, Maryland, reports that health types have concluded their investigation of Salmonella Infantis infections linked to food eaten at a March 5 benefit pancake breakfast at Trinity United Church of Christ in Thurmont.

Dr. Barbara Brookmyer, county health officer, said in an e-mail that 18 cases of infection were reported, nine confirmed by stool sample testing, and nine probable.

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.

Neil Gaffney, press officer with the U.S. Department of Agriculture’s Food Safety and Inspection Service, said its investigation is ongoing. The USDA investigation includes tracing the pork products’ origin.
