In a letter to the company's owner, the House Energy and Commerce Committee said its investigators had obtained records showing Wright County Egg received 426 positive results for salmonella between 2008 and 2010. The company recalled 380 million eggs in August after its products were linked to hundreds of illnesses.
The committee said the positive results found over the last two years included 73 samples that were potentially positive for Salmonella Enteritidis, the strain responsible for the recent outbreak.
The owner of Wright County Egg, Austin "Jack" DeCoster, was scheduled to testify before the panel next week. A company spokeswoman did not immediately respond to a request for comment.
In the letter to DeCoster, committee chairman Henry Waxman, D-Calif., and investigations subcommittee chairman Bart Stupak, D-Mich., said they were concerned that DeCoster did not inform them of the positive results when the panel asked him to provide documents in August. One of the questions the panel asked DeCoster was to show dates and results of all positive findings after microbiological testing.
"When you testify before the committee, we ask that you come prepared to explain why your facilities tested potentially positive for Salmonella Enteritidis contamination on so many occasions, what steps you took to address the contamination identified in these test results, and whether you shared these results with FDA or other federal or state food safety officials," Waxman and Stupak wrote.
According to the committee, the company received as many as 67 positive results this year alone. That includes one positive result for Salmonella Enteritidis on July 26, less than three weeks before the company recalled the eggs. The recall eventually grew to a half-million eggs and included another company, Hillandale Farms, that also has ties to DeCoster.
The letter does not say how the committee obtained the results or from whom.
