Washington, D.C. ? A congressman challenged Stewart Parnell, holding up a container of the peanut seller’s products and asking if he’d dare eat them.

Parnell pleaded the Fifth.

The owner of the peanut company at the heart of the massive salmonella recall refused to answer the lawmaker’s questions — or any others — Wednesday about the bacteria-tainted products he defiantly told employees to ship to some 50 manufacturers of cookies, crackers and ice cream.

“Turn them loose,” Parnell had told his plant manager in an internal e-mail disclosed at the House hearing. The e-mail referred to products that once were deemed contaminated but were cleared in a second test last year.

Summoned by congressional subpoena, the owner of Peanut Corp. of America repeatedly invoked his right not to incriminate himself at the House Energy and Commerce subcommittee hearing on the salmonella outbreak that has sickened some 600 people, may be linked to nine deaths — the latest reported in Ohio on Wednesday — and resulted in one of the largest product recalls of more than 1,900 items.

Parnell sat stiffly, his hands folded in his lap at the witness table, as Rep. Greg Walden, R-Ore., held up a clear jar of his company’s products wrapped in crime-scene tape and asked if he would eat them.

“Mr. Chairman and members of the committee, on advice of my counsel, I respectfully decline to answer your questions based on the protections afforded me under the U.S. Constitution,” Parnell responded.

After he repeated the statement several times, lawmakers dismissed him from the hearing.
