Follow-Up: Broccoli Sprout Salmonella Outbreak Declared Over: 34 Sickened in Six States, FDA Traces Source to Imported Seed Lot from New Zealand
The U.S. Food and Drug Administration (FDA) said in a November 4 update that the Centers for Disease Control and Prevention (CDC) has declared the Salmonella outbreak linked to broccoli sprouts over, and that the FDA's investigation is complete. A total of 34 people infected with the outbreak strain were reported from six states, with illness onset dates ranging from July 7 to September 11, 2026. There were three hospitalizations and no deaths.
GSM previously reported that the outbreak stood at 32 cases in six states in early October, with seed lot W4105 identified as the suspect lot. The final case count is 34. Of the 30 people interviewed, 29 (97%) reported eating sprouts or microgreens, 25 reported specifically eating broccoli sprouts, and one reported eating a microgreen mix containing broccoli microgreens.
During the investigation, the FDA and state partners collected samples of broccoli sprouts and broccoli seeds. Evergreen Fresh Sprouts-brand broccoli sprout samples collected by Washington state and Montana state health officials tested positive for Salmonella and matched the outbreak strain by whole genome sequencing, and broccoli seed samples the FDA collected from the domestic seed supplier also matched. Traceback showed the broccoli seeds were originally imported from New Zealand; the domestic supplier recalled the lot, and several downstream companies followed with their own recalls.
The recalled seeds include Gardeners Basics Waltham 29 Broccoli Sprouting Seeds (1-pound pouch, UPC 848137042889), Eden Brothers calabrese broccoli seeds (lots 1022067 and 1022068), and Home Grown green sprouting calabrese broccoli seeds (8-ounce, lot code AUG172026, sold on Amazon). All affected broccoli sprouts are past expiration and no longer available for sale.
The FDA noted that the recalled seeds have a long shelf life and may still be in consumers' homes. Consumers, restaurants, and retailers should check their homes and storage, should not use the recalled broccoli seeds, and should carefully clean and sanitize any surfaces or containers the recalled sprouts or seeds touched. Anyone who develops symptoms resembling a Salmonella infection after eating recalled sprouts or handling recalled seeds should contact a health care provider. Salmonella symptoms usually begin 12 to 72 hours after eating contaminated food, include diarrhea, fever and abdominal cramps, and typically last four to seven days.
