Health officials expect to announce the source of the largest salmonella outbreak in recent S.C. history by the end of the week. Lab workers should determine which food was contaminated with the bacteria in the next few days.

"They have gotten some information back, but its not enough to be conclusive," said Missy Reese, spokeswoman for the Department of Health and Environmental Control’s Wateree Health District.

One person died, 51 people were hospitalized and 293 patrons reported symptoms after eating at a Camden buffet restaurant between May 19-22, according to DHEC. It is the largest food-borne outbreak in recent state history.
