A senior epidemiologist at the public health division in Oregon identified the Rhode Island-based company as a possible source after comparing shopping receipts of those who got sick.
But, William Keene says questions remain, such as whether the meat or the pepper is the culprit.
But a Daniele spokesman says there's "no evidence" that points to his company as the source. He says two of the company's three plants have been tested and found free of bacteria.
The spokesman says the recall is being issued in case more evidence implicates the salami.
The company has set up a hot line for consumers or distributors at (888) 345-4160.
