Alaska officials say bags of chopped romaine lettuce are being recalled over concerns of potential listeria contamination.

The state Department of Conservation has confirmed that the 2-pound bags of chopped rine lettuce from True Leaf Farms, which have a use-by date of Sept. 29, were distributed in Alaska by Church Brothers, LLC.

There have been no reported illnesses, but listeria can be fatal and is particularly dangerous to people with weakened immune systems, including infants, the elderly and people with HIV or those who are undergoing chemotherapy.

Officials urge those who purchased the potentially tainted product, which carries a bag and box code of B256-46438-8, to throw it out.
