Even as the number of cyclospora cases in the United States hit record levels, top health regulators insisted that consumers could still trust what they were eating. “The U.S. food supply is safe,” Donald Prater, the acting deputy commissioner for food at the U.S. Food and Drug Administration, told attendees Monday at the annual meeting of the International Association for Food Protection.

Ten days ago, the US Food and Drug Administration (FDA) announced that a sample of iceberg lettuce from Taylor Farms de Mexico tested positive for Cyclospora, the microscopic parasite responsible for a nine-state outbreak of foodborne illness. The next day, the agency noted it was a false-positive test result. (Holohan, 7/28)

There are promising signs that illnesses linked to contaminated lettuce may be slowing in Michigan, the hot spot of the multistate outbreak of cyclosporiasis in the U.S. That doesn’t mean all the affected produce is gone from stores or restaurants, or that more people aren’t still getting sick, experts say.

There are now 33 confirmed cases of cyclosporiasis in New Hampshire, according to the latest data from the New Hampshire Department of Health and Human Services. Seventeen of those cases are people who reported eating lettuce from locations that served recalled Taylor Farms products. All of those cases are linked to exposure to recalled lettuce at Cheshire Medical Center in Keene, according to Jake Leon, spokesperson for the state Department of Health and Human Services. (7/28)

Infants are far more vulnerable than older children to severe illness from viruses like influenza, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and SARS-CoV-2, the virus that causes COVID-19, according to a study yesterday in Pediatrics. The findings also highlight significant differences in how respiratory infections affect infants, ranging from asymptomatic or mildly symptomatic infections managed at home to severe illness requiring hospital or emergency department (ED) care. (Bergeson, 7/28)

Pregnant women and parents of young kids said they’d prefer getting the maternal respiratory syncytial virus (RSV) vaccination during pregnancy as the primary way to protect their child against the virus, according to the results of a national survey published late last week in JAMA Network Open. (Boden, 7/28)

Confirmed cases in Congo’s ongoing Ebola outbreak have reached 3,262, its Ministry of Health said in an overnight update, nearly the same as the 2018-2020 outbreak that is the largest ever recorded in the country. Data from the Congolese health ministry showed that 1,437 patients have died out of the 3,262 cases, in what officials have said is the fastest Ebola outbreak on record, concentrated in the eastern Ituri province.

A Public Health Alerts report published today describes 11 cases of infection with Babesia, a genus of parasites transmitted by Ixodes ticks, in Nova Scotia since 2023, seven of which were confirmed last year. The paper also notes a potential detection—though not a confirmation—of Babesia among almost 11,000 blood samples from donors in the province. (Wappes, 7/28)

"Rethink. Rebuild. Rise." That's the theme of this year's International AIDS conference, which began this week in Rio de Janeiro. "Rethink" is perhaps an understatement. This year, there are encouraging signs regarding the ongoing epidemic — even though 1.2 million people acquired the virus in 2025, the number of AIDS-related deaths was 547,000, the lowest number in 30 years. Yet the fate of the global campaign to end AIDS as a public health threat by 2030 is now in doubt, as the Trump administration's aid cuts have taken a tremendous toll. (Bouscaren, 7/28)

For years, Bayer and the biotech giant it purchased, Monsanto, have faced allegations that glyphosate, the active ingredient in its popular herbicide Roundup, causes cancer. The saga has resulted in over 100,000 lawsuits, billions of dollars in settlement funds, a Supreme Court case and several actions by the Trump administration. But amidst the flurry of legal activity, few have stopped to ask a fundamental question: Why are we spraying so much glyphosate in the first place? The answer, in many cases, is animal agriculture.
