Most of what we cover in this series is still open — a case count that keeps climbing, a source nobody's named yet. This round is different. FDA just published executive summaries closing out five separate outbreak investigations at once, totaling 138 illnesses. Closed cases are worth covering because they're the rare moment we actually get the full story — what the product was, who made it, and in one case, why it took federal investigators over three years to even realize five people in four different states had gotten sick from the same thing.
NewThe Three-Year Mystery: Clover Hill Dairy's Requesón Listeria Outbreak
This is the one worth slowing down for. Clover Hill Dairy, LLC of Mechanicsville, Maryland made a fresh soft cheese called requesón that sickened 15 people across Illinois, Maryland, New York, and Virginia — 14 of them hospitalized, and one person in Maryland died. A 93% hospitalization rate is unusually high, which tracks with Listeria being especially dangerous for older adults, pregnant people, and anyone with a weakened immune system.
Here's the part that makes this outbreak genuinely unusual: the illnesses stretch back to March 6, 2023 — this outbreak ran three years and four months before it was finally closed out this past July. That's not FDA sitting on bad news; it's a real detection problem. With only a case or two showing up each year, scattered across four different states, the genetic fingerprint of this specific Listeria strain just sat in CDC's national tracking database (PulseNet) without enough of a pattern to trigger an investigation. The break came in May 2026, when a county health department, a state agriculture lab, and a retail sampling program together traced a positive cheese sample at a New York retailer back to Clover Hill — closing a three-year-old mystery in about fifteen days once they had the right lead. Whole genome sequencing is what let investigators connect cases separated by years, something that wouldn't have been possible even a decade ago.
One more detail worth knowing: the final illness in this outbreak happened five weeks after recalls had already started, which the reporting attributes to the product having been sold and eaten under other brand names before the recall notices caught up. If you buy fresh soft cheeses regularly, this is a good reminder that recalls don't always reach every product on a shelf at the same moment.
NewGuatemalan Cantaloupe — Salmonella FDA Traced Back Five Years
Ayco Farms, Inc. of Pompano Beach, Florida — the importer and distributor for cantaloupes grown on two Guatemalan farms — is behind a Salmonella Newport outbreak that sickened 70 people earlier this year. FDA issued an Import Alert and recall orders after finding Salmonella in environmental samples. The striking part: investigators found Salmonella in Guatemala that genetically matches illnesses going back five years, from 2021 to 2026 — meaning this wasn't a one-time contamination event, but a recurring problem at the source that took years to actually connect to real illnesses.
Worth being precise here, since it's easy to mix up: this is a different, already-closed Salmonella Newport outbreak from earlier in 2026 — not the same as the Salmonella Newport outbreak we've been tracking as still open in this series (the one sitting at 97 illnesses with no food source named yet, more on that below). Same strain name, two unrelated outbreaks.
NewA Moringa Supplement Supplier Refused to Let FDA In
This one's an accountability story more than a food-safety one. An outbreak of Salmonella Newport and Salmonella Kentucky tied to Rosabella-brand moringa capsules (distributed by Ambrosia Brands, LLC) sickened 10 people across seven states. When FDA's Office of Global Policy and Strategy tried to inspect the powder supplier and collect records in March, the supplier refused access and would not provide records — and FDA's summary notes no source of contamination was ever confirmed as a result. We've touched on this same pattern before in this series: the moringa/supergreens supply chain has had repeat problems this year with suppliers that never get named publicly (see the Foods Alive Organic Moringa Leaf Powder recall back in Part 2/3, tied to an unnamed supplier shared with other brands) — this is a separate incident, but it's the same underlying shape of problem: a powder ingredient supplier that stays anonymous even after people get sick.
A second, smaller moringa outbreak also closed this round — Mogo-brand moringa capsules sickened 34 people (11 hospitalized, plus one breastfed infant) with Salmonella Typhimurium, tied to a redacted powder supplier in India. TNVitamins capsules were recalled in connection with that same investigation. FDA's own count makes it three separate moringa-related Salmonella outbreaks in 2026 alone.
ClosedAlso Closed Out: Raw Farm's Second E. coli Outbreak
Raw Farm raw cheddar and raw milk caused an E. coli O157:H7 outbreak sickening 9 people across California, Florida, and Texas — most of them children under five. This is Raw Farm's second cheddar-linked outbreak in about two years (an earlier one in 2024 sickened 11 people). No supplier-refusal issue here; FDA completed its inspections without resistance.
UpdatedHolding Steady
Everything else we've been tracking is unchanged since Part 6: the jalapeño Salmonella outbreak is still at 431 illnesses/32 states with no federal update since August 21; the Hepatitis A outbreak tied to La Serranita concha negra (black clams) is still 37 illnesses/30 hospitalized, no CDC update since September 3; the frozen berry E. coli recall (Great Value + GreenWise) hasn't grown past 17 illnesses; and our own broccoli sprouts recall coverage still matches CDC's latest numbers exactly — 22 illnesses, four states, 2 hospitalized. Made Fresh Salads' Listeria recall still has zero reported illnesses. And separate from everything closed out above, FDA still can't name a source for two other outbreaks: the Salmonella Newport outbreak sitting at 97 illnesses, and the second, unrelated Cyclospora cluster we first flagged in Part 6 — both unchanged since then.
