Democratic lawmakers are questioning whether a Boar's Head deli meat plant at the center of last year's deadly listeria outbreak will be fit to reopen. Rep. Rosa DeLauro, of Connecticut, sent a letter Monday asking company officials to appear before the Congressional Food Safety Caucus to discuss “a repeated pattern of food safety negligence that jeopardized Americans' public health.” The letter, signed by nine other Democrats, cited Associated Press reporting that described sanitation problems in recent months at Boar’s Head plants in three states.
