WASHINGTON (WOAI) — A listeria food poisoning outbreak that has killed three people and led to one pregnancy loss is linked to newly recalled heat-and-eat chicken fettuccine alfredo products sold at Kroger and Walmart stores, according to the U.S. Department of Agriculture.

Additionally, there have been reports of illnesses in 13 states. The number of sick people is likely higher than now known cases and may be detected in additional states. Officials are continuing to receive reports of illnesses linked to the product and “are concerned that contamination is still occurring,” the CDC said.

The affected products were sold under the 'Marketside' brand at Walmart and the 'Home Chef' brand at Kroger.

You are advised to either dispose of the products or return them to the store for a refund.

The products were shipped to Kroger and Walmart retail locations nationwide:

• 32.8-oz. tray packages containing “MARKETSIDE GRILLED CHICKEN ALFREDO WITH FETTUCCINE Tender Pasta with Creamy Alfredo Sauce, White Meat Chicken and Shaved Parmesan Cheese” with best-by date 06/27/25 or prior.
• 12.3 oz. tray packages containing “MARKETSIDE GRILLED CHICKEN ALFREDO WITH FETTUCCINE Tender Pasta with Creamy Alfredo Sauce, White Meat Chicken, Broccoli and Shaved Parmesan Cheese” with best-by date 06/26/25 or prior.
• 12.5 oz. tray packages containing “HOME CHEF Heat & Eat Chicken Fettuccine Alfredo with pasta, grilled white meat chicken, and Parmesan cheese” with best-by date 06/19/25 or prior.

The products bear the USDA mark of inspection on the product label as well as establishment numbers “EST. P-50784,” “EST. P-47770,” or “EST. P-47718” printed on the side of the packaging.

Listeriosis can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance and convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms. An invasive infection spreads beyond the gastrointestinal tract. In pregnant women, the infection can cause miscarriages, stillbirths, premature delivery or life-threatening infection of the newborn. In addition, serious and sometimes fatal infections in older adults and people with weakened immune systems. Listeriosis is treated with antibiotics. People in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.

About 1,600 people get sick each year from listeria infections and about 260 die, the CDC said. Federal officials in December said they were revamping protocols to prevent listeria infections after several high-profile outbreaks, including one linked to Boar’s Head deli meats that led to 10 deaths and more than 60 illnesses last year.
