In December 2022, CDC, state and local public health and agriculture agencies investigated an outbreak of Salmonella Typhimurium infections. The implicated vehicle was alfalfa sprouts consumed at home or in restaurants. Sixty-three outbreak associated cases were reported from 8 states. Illnesses started on dates ranging from December 2, 2022, to February 2, 2023. Of 50 people interviewed, 35 (70%) reported eating alfalfa sprouts.

FDA’s traceback evidence indicated that the restaurants and grocery stores identified in this outbreak received raw alfalfa sprouts from SunSprout Enterprises. Additionally, eight of the individuals identified in this outbreak confirmed they had purchased Sun Sprouts-brand alfalfa sprouts from local grocery stores.

On December 29, 2022, SunSprout Enterprises recalled four lots of raw alfalfa sprouts, lot numbers 4211, 5211, 3212, and 4212. The sprouts were distributed to food service and grocery customers in Nebraska, Kansas, and Iowa between late November and mid-December 2022. Recalled sprouts had best-by dates between 12/10/2022 and 1/7/2023.

The outbreak was declared over on February 28, 2023.
