Salmonella found in feed used at farms with tainted eggs

Salmonella has been found in the feed used at the farms linked to the massive outbreak and subsequent recall of eggs and was at least one of the causes, federal officials said today. The U.S. Centers for Disease Control and Prevention said this is the largest outbreak of Salmonella enteritidis since records starting being kept in the 1970s.

The feed was made at Wright County Egg -- the main source of the 500 million-plus egg recall. That farm also supplied feed to Hillandale Farms, the other major egg producer involved in the recall. The CDC now puts the number of those sickened at 2,403 -- but that only includes cases that were documented by medical professionals and transmitted to the CDC. Food safety experts say the actual figure of people sickened is several times that.
