SCIENCE & HEALTH
It's the garnish nobody thinks twice about — a fistful of pale, wiry sprouts scattered on a sandwich or folded into a salad, marketed as the healthy choice, the fresh choice, the choice that makes you feel virtuous for ordering it. But across 15 states this summer, that innocuous pile of alfalfa sprouts has been quietly making people violently ill, and health investigators say the outbreak is still not fully contained.
As of the latest CDC update, 55 people across Florida, Indiana, Iowa, Kansas, Michigan, Minnesota, New Hampshire, New York, North Carolina, North Dakota, Pennsylvania, South Carolina, South Dakota, Washington and Wisconsin have been confirmed sick in a multistate outbreak involving two different dangerous pathogens at once: multiple strains of Shiga toxin-producing E. coli and a strain of Salmonella. Of those cases, 46 people were infected with E. coli, seven with Salmonella, and two unlucky patients were infected with both simultaneously. At least four people have been hospitalized. No deaths have been reported.
The source, according to the CDC and FDA's joint traceback investigation: alfalfa sprouts grown and distributed by Everything Sprouts, LLC, a company based in Minneapolis that sold its product under both the Everything Sprouts and Calco brand names.
HOW INVESTIGATORS CRACKED THE CASE
Outbreak investigations like this one typically start the same way — a cluster of unrelated people, in unrelated cities, showing up at doctors' offices and emergency rooms with the same nasty combination of symptoms, and lab tests revealing they're infected with genetically near-identical strains of bacteria despite having no apparent connection to one another.
For E. coli infections caused by Shiga toxin-producing strains, that means severe stomach cramps, diarrhea that can turn bloody, and vomiting, symptoms that typically appear within three to four days of exposure and can last about a week. Salmonella infections bring their own miserable cocktail: diarrhea, fever and stomach cramps, usually striking within six hours to six days of eating contaminated food. Both infections can, in rare but serious cases, lead to hospitalization — and Shiga toxin-producing E. coli in particular carries the risk of a life-threatening kidney complication called hemolytic uremic syndrome, which disproportionately strikes young children and older adults.
Investigators traced illnesses back as far as May 31, 2026, with the most recent confirmed case falling ill on August 8 — meaning this outbreak had been quietly circulating for close to two and a half months before the public recall arrived. Of the people investigators were able to interview about what they'd eaten in the week before falling ill, a striking 76% reported eating alfalfa sprouts, a signal strong enough, combined with lab and traceback data, to point investigators directly at Everything Sprouts' Minneapolis facility.
Minnesota and Wisconsin bore the brunt of the outbreak, accounting for 21 and 17 cases respectively — more than two-thirds of all confirmed illnesses — consistent with a regional distribution network centered on the Upper Midwest before fanning out to grocery stores and food service accounts across more than a dozen other states.
THE RECALL
On August 22, 2026, Everything Sprouts, LLC issued a voluntary recall covering its 5-ounce plastic containers of alfalfa sprouts, distributed under lot numbers 222, 223, 225, 226 and 230, dating back to product shipped since May 27. The recall wasn't limited to sprouts sold on their own — the same contaminated alfalfa sprouts had also been mixed into the company's Crunchy Protein Sprout Mix cups and Zesty Garlic Mix cups, both sold in 5-ounce containers under the same lot numbers, widening the universe of potentially contaminated products sitting in refrigerated cases and home refrigerators across the affected states.
Consumers who purchased any of these products were urged not to eat them, and instead to throw them away or return them to the place of purchase. Because Shiga toxin-producing E. coli and Salmonella can both survive on surfaces and cross-contaminate other foods, food safety officials also recommended that anyone who had stored the recalled sprouts in a refrigerator thoroughly clean and sanitize any shelves, drawers or containers the product touched.
The recall has already drawn legal fallout. Food safety attorney Bill Marler, a well-known figure in outbreak litigation, confirmed he is representing at least two Wisconsin consumers sickened in the outbreak, including one who was hospitalized with salmonella, and has indicated the company bears responsibility for the contamination reaching consumers' plates.
WHY SPROUTS, OF ALL FOODS, KEEP CAUSING OUTBREAKS
If this all sounds oddly familiar, that's because it should. Raw sprouts — alfalfa, bean, clover, and others — have one of the worst safety track records of any commonly eaten raw vegetable, and food safety experts say the biology behind that reputation is straightforward and largely unfixable through washing alone.
Sprouts are grown by soaking seeds and then keeping them warm, humid and damp for several days until they germinate — conditions that happen to be nearly perfect for bacterial growth as well. If a seed carries even a tiny, undetectable level of contamination, whether from contaminated water, soil, or animal waste at some point in the supply chain, the warm, wet sprouting environment can allow that small number of bacteria to multiply into the millions by the time the sprouts reach a grocery shelf. Worse, pathogens can work their way inside the seed itself, tucked into cracks and crevices where rinsing or surface washing simply cannot reach them.
Between 2000 and 2020, CDC's National Outbreak Reporting System logged at least 53 separate sprout-associated outbreaks in the United States, responsible for 1,498 illnesses, 179 hospitalizations and five deaths. The most catastrophic sprout-linked outbreak in recent memory struck Germany in 2011, when E. coli O104:H4-contaminated fenugreek sprouts sickened more than 4,000 people and killed over 50, one of the deadliest foodborne outbreaks in modern European history. Food safety regulators have long known sprouts are a special-case risk category; the FDA and CDC have issued standing advisories for years recommending that children, older adults, pregnant women and anyone with a weakened immune system avoid raw sprouts entirely, cooked or not.
The only truly reliable way to neutralize the risk, food safety experts note, is heat — boiling sprouts for around five minutes kills the bacteria that rinsing cannot reach. For a food item marketed and consumed almost exclusively raw, that inconvenient fact has never quite caught on with the sandwich-and-salad-eating public.
EXPERT PERSPECTIVE
Public health investigators tracking this outbreak have emphasized that the dual-pathogen nature of this event — both E. coli and Salmonella traced to the same product — is itself a warning sign about contamination at the source, since a single food item playing host to two entirely different bacterial species suggests broader sanitation or water-quality issues at the growing or processing stage rather than an isolated, one-off contamination event. Food safety attorneys and advocates tracking the case have pointed to it as part of a broader pattern this summer: as of late August, federal regulators were juggling nearly twenty separate open foodborne illness investigations nationwide, with well over 12,000 people sickened and hundreds hospitalized across all active outbreaks combined, a volume some food-safety trackers have described as an unusually active summer surge.
WHAT THIS MEANS FOR YOU
First, the practical step: if you have any Everything Sprouts or Calco-brand alfalfa sprouts, or any Everything Sprouts Crunchy Protein Sprout Mix or Zesty Garlic Mix cups, sitting in your refrigerator, check the lot numbers — 222, 223, 225, 226 or 230 — and throw the product away rather than eating it, even if it looks and smells fine. Contaminated sprouts show no visible signs of the bacteria that make them dangerous.
Second, the bigger-picture step: if you're someone who regularly orders sandwiches, wraps or salads topped with raw sprouts, especially at delis, sub shops or salad bars where you can't verify the source, it's worth knowing that public health agencies have quietly flagged this category of food as disproportionately risky for years, not just during active outbreaks. If you're pregnant, over 65, immunocompromised, or feeding young children, the standing medical advice is to skip raw sprouts altogether or make sure they're thoroughly cooked first.
And if you or a family member develops severe stomach cramps, bloody diarrhea or persistent vomiting in the days after eating sprouts purchased in one of the affected states, contact a doctor and mention the exposure specifically — early recognition matters, particularly for young children and older adults who face the highest risk of the rare but serious kidney complications that Shiga toxin-producing E. coli can trigger.
CONCLUSION
Fifty-five confirmed illnesses, 15 states, two different dangerous pathogens riding on the same innocuous garnish — it's a reminder that "fresh" and "healthy" marketing on a food label says nothing about what's actually happening inside a sprouting facility. The Everything Sprouts recall may already be working its way off store shelves, but with the investigation still technically open and the last confirmed illness only weeks old, health officials aren't ready to call this outbreak over just yet. Until they do, the safest sprout is the one that's been boiled — or the one left off your plate entirely.
