Hannaford Supermarkets has issued a recall for roasted and salted shelled sunflower seeds sold from the stores’ bulk bins.

The Scarborough-based grocery chain posted the recall Tuesday after being notified that a supplier issued a recall because of the potential presence of listeria, according to the company’s website.

Listeria is a type of bacteria that can lead to a serious infection. No illnesses have been reported in connection with the recall, and the affected product has been removed from stores, said a release from Hannaford.

The supplier, SunOpta, a producer of organic and specialty foods, voluntarily recalled certain sunflower kernel products produced at the company’s Minnesota facility because the items may have been contaminated with Listeria monocytogenes. The roasted and salted sunflower seeds were sold at Hannaford as an unpackaged bulk item in the produce department.

Hannaford customers who purchased this product should not consume it and may return the item for a full refund, the company said in a release. Consumers seeking information may email contactus@sunopta.com or call 1-877-237-4374.

Also on Tuesday, a Pasco, Washington, company has expanded its recall of frozen vegetables linked to a listeria outbreak that has sickened eight people.

One person from Maryland and one from Washington have died but health officials do not consider listeria to be the cause of death for either person.

The Centers for Disease Control says the recall by CRF Frozen Foods began in April and was expanded on Monday. The recall now includes all organic and traditional frozen vegetable and fruit products processed in the company’s Pasco facility since May 1, 2014.

About 358 products sold under 42 separate brands were recalled.

The CDC says the listeria outbreak that started in September 2013 has sickened people in Washington, Maryland and California. Two illnesses were reported in 2016 and six were reported between 2013 and 2015. All eight people were hospitalized.
