IOWA CITY, Iowa (AP) -- An Iowa egg producer diverted eggs from the food supply after a recent inspection discovered salmonella in two of its barns.
Centrum Valley Farms told The Associated Press the FDA found the strain called salmonella heidelberg in two of six poultry houses tested at its Clarion facility in May.
The company said the finding didn't mean eggs were tainted. But it withheld them until they tested negative and were approved for sale by the FDA.
The plant's under strict oversight because it was implicated in the 2010 salmonella outbreak, which caused a recall of 550 million eggs and sickened hundreds. Centrum Valley took over management afterward, vowing to improve operations.
In an Aug. 14 letter, the FDA said it was concerned about the presence of salmonella and ordered corrective action.
