Italian authorities are investigating a Listeria outbreak that has sickened 22 people and killed one.
Mortadella sold by Veroni is being looked at as a potential source but an official link has not been confirmed by authorities.
In early November, a number of recalls were published for Veroni mortadella due to potential Listeria contamination.

The Ministry of Health (Ministero della Salute) issued a warning covering a few batches of the Veroni Supergiant Mortadella packed in small portions due to the presence of Listeria monocytogenes.
Veroni said it immediately and voluntarily alerted the market, recalling all batches of Supergiant Mortadella with and without pistachios in portions that had expiry dates before Dec. 27, 2022.
