Hannaford Supermarkets this morning issued a voluntary recall of ground beef and is advising consumers to check for any ground beef purchased at its stores with a “sell-by” date of Dec. 17 or earlier.

These ground beef products may be contaminated with a Salmonella typhimurium strain (S. typhimurium). The information received to date indicates that 10 people have become ill, all of whom have indicated that they purchased ground beef between Oct. 12 and Nov. 20.

The 85 percent lean variety of ground beef was most common to affected individuals. In an abundance of caution, Hannaford is voluntarily recalling all ground beef sold during this period and will accept returns for a full refund for any ground beef with sell-by dates of Dec. 17 or earlier.

Customers who have questions are encouraged to call the Hannaford Customer Information Center, 8 a.m. to 8 p.m. – 800-213-9040, option 6.
