The U.S. Food and Drug Administration (FDA), along with the Centers for Disease Control and Prevention (CDC) and state and local partners, is investigating a multistate outbreak of Salmonella Typhimurium infections. FDA’s traceback investigation is ongoing but has identified Sun Sprouts brand alfalfa sprouts grown by SunSprout Enterprises of Fremont, NE as a likely source of illnesses in this outbreak.

Based on the epidemiologic information provided by the CDC along with interviews conducted by state and local public health officials, the individuals identified in this outbreak reported consuming alfalfa sprouts prior to their illness onset, either at local restaurants or in their homes after purchasing from local grocery stores. Preliminary traceback evidence indicates that the restaurants and grocery stores identified in this outbreak received alfalfa sprouts from SunSprout Enterprises. Additionally, two of the individuals identified in this outbreak confirmed they had purchased Sun Sprouts brand alfalfa sprouts from their local grocery store. Whole Genome Sequencing (WGS) conducted on clinical samples collected from ill individuals identified 15 isolates that matched the outbreak strain: OK (1), NE (8), and SD (6). WGS for additional clinical isolates are still pending sequencing.

On December 29, 2022, SunSprout Enterprises initiated a voluntary recall of two lots (# 4211 and 5211) of raw alfalfa sprouts due to potential contamination with Salmonella. On the same day, SunSprout Enterprises expanded their voluntary recall to include two additional lots (# 3212, and 4212) of raw alfalfa sprouts. The raw alfalfa sprouts for all recalled lots (#4211, 5211, 3212, and 4212) are packaged in 4-ounce clamshells and 2.5 lb packages with best sold by dates between 12/10/2022 and 1/7/2023.

The investigation is ongoing to determine the source of contamination and whether additional products are linked to illnesses. FDA will update this advisory should additional consumer safety information become available.
