New ByHeart-commissioned research suggests that sulfite-reducing clostridia (SRC) enumeration, the “gold-standard” test for C. botulinum in powdered infant formula, which was used by Nara Organics prior to the ongoing outbreak, is insufficient. Experts who spoke to Food Safety Magazine agree C. botulinum should be considered as a foreseeable hazard requiring specific preventive controls.
Three babies in three states have been sickened in the second infant botulism outbreak identified since late-2025. All patients were fed Nara Organics Whole Milk Infant Formula. A recall has been issued, and product testing is underway.
The now-recalled requeson cheese was produced by Maryland-based Clover Hill Dairy. Patients have been identified in New York, Maryland, and Virginia, with the earliest illness occurring in early 2023 and the most recent in May 2026.
FDA did not identify deficiencies in ByHeart’s production facilities that could explain the outbreak, but a powdered milk ingredient did test positive for C. botulinum. ByHeart is developing an action plan based on data generated from the investigations.
The latest data from the UK Health Security Agency (UKHSA) show that the number of Campylobacter and Salmonella infections in England remained high or increased in 2025, while listeriosis cases stayed stable from the previous year.
The agency has also reopened a previously closed Salmonella outbreak investigation linked to powdered moringa supplements, with 22 new reported illnesses in four additional states.
CDC has published a report summarizing the multistate enteric disease outbreaks it solved in 2024, of which 29 were foodborne, resulting in 1,533 illnesses, 519 hospitalizations, and 19 deaths.
The E. coli outbreak involving Raw Farm unpasteurized dairy products has ended with one raw cheese sample matching isolates from a different 2025 outbreak. In an April 29 hearing, Congresspeople questioned whether U.S. Health Secretary Kennedy influenced FDA’s failure to mandate a recall.
In 2025, a genetically unique hybrid STEC/STEC strain was the cause of a foodborne illness outbreak that affected exclusively adults, with 90 percent of patients developing hemolytic uremic syndrome (HUS) and three deaths occurring.
The outbreak strain of Salmonella Bochum is extremely rare. Children and adolescents aged 2–15 years represent 75 percent of outbreak patients. Patient interviews and a case-control study point to a certain brand of chocolate-hazelnut spread as the vehicle of illness.
