The Centers for Disease Control and Prevention is warning everyone in the country to back away from pre-cut cantaloupe unless you're certain the fruit in question is not tied to a large, nationwide Salmonella outbreak that is unusually severe.

So far, 117 cases of infection across 34 states have been identified in the outbreak. The cases are in people ranging from infants to the elderly, including a 100-year-old. Of the cases, 61 (52 percent) have been hospitalized, and two deaths have been reported in Minnesota.

The CDC attributes the unusually high hospitalization rate to the fact that the pre-cut fruit was served at long-term care facilities and childcare centers. The elderly and young children are at higher risk of severe Salmonella illness.

With the US maternal death rate already the highest among affluent countries and still rising, a new study by the Centers for Disease Control and Prevention suggests pregnant people experience high levels of mistreatment and discrimination during maternity care.

The survey of 2,402 mothers from around the country found that one in five experienced some type of mistreatment by health care providers during their maternity care. The most common forms included having health concerns ignored or dismissed (10 percent), being shouted at or scolded (7 percent), having their physical privacy violated (5 percent), and having a provider threaten to withhold treatment or force them to accept unwanted treatment (5 percent). Additionally, nearly 30 percent of survey takers reported experiencing discrimination during their maternity care, including their race, age, weight, and income.

Black, Hispanic, and multi-racial mothers reported the highest rates of mistreatment and discrimination. These racial disparities mirror disparities seen in pregnancy outcomes; mothers in these groups face the highest maternal mortality rates in the country. Black mothers, for instance, are three times more likely to die from pregnancy-related causes than white mothers.

The Food and Drug Administration is warning consumers not to use any at-home tests made by Universal Meditech, Inc. (UMI), the company behind an illegal medical lab hidden in a warehouse in the small city of Reedley, California. The lab was shut down earlier this year by local, state, and federal agencies, which are still working to clear the site, properly dispose of all its hazardous contents, and investigate those responsible.

"UMI has notified the FDA that it has stopped all operations and is no longer providing support for its tests," the FDA said in a safety communication Friday . "The FDA is not able to confirm the performance of UMI’s tests, raising concerns that the tests may not be safe and effective."

UMI manufactured a variety of strip-based tests, mostly pregnancy tests, but also tests for ovulation, ketones, and alcohol in breast milk. The tests were sold under several names—including DiagnosUS, HealthyWiser, DeTec, and PrestiBio. They were available online from at least four distributors, which may not have identified UMI as the manufacturer. The known distributors are: AC&C Distribution, LLC; HealthyWiser; Home Health US Inc.; and Prestige Biotech Inc. The FDA cautions that there may be other distributors that it doesn't know about.

A Florida man's unexplained case of leprosy last year adds to mounting evidence that the rare and often misunderstood bacterial infection has become endemic to the central part of the Sunshine State—and that it may, in fact, lurk in the environment there, possibly in the soil.

In a research letter appearing in the August issue of Emerging Infectious Diseases, three dermatologists detailed the man's case and their concerns for local transmission. They note that the 54-year-old man, like several others in the state who contracted the disease, reported no established risk factors that might explain their infection. He hadn't traveled abroad, where he could have picked up the infection, or had any exposure to armadillos, which live in Florida and naturally carry the bacteria that cause leprosy. He also didn't have any prolonged contact with people from leprosy-endemic countries or connections to anyone known to have leprosy.

But he did spend a lot of time outdoors; he worked as a landscaper. In fact, many of the recent Florida cases lacked traditional risk factors but reported spending a lot of time outdoors. The similarity "supports the investigation into environmental reservoirs as a potential source of transmission," the doctors wrote.

For a fourth consecutive summer, COVID-19 is on the rise, though this year's warm-weather wave appears milder than those in the emergency period of the pandemic.

COVID-19 indicators of hospital admissions, emergency department visits, test positivity, and wastewater levels have all been increasing in the past month, with a peak not yet clearly in sight, according to data tracking by the Centers for Disease Control and Prevention. From June 10 to July 29, test positivity rose from 4.1 percent to 8.9 percent. For reference, the most recent winter wave had a peak test positivity of 10.6 percent on December 31, 2022.

On the brighter side, however, weekly COVID-19 hospital admissions and deaths continue to be at their lowest points since the start of the pandemic. For now, deaths do not appear to be rising, though there are lags in data reporting. Weekly new hospital admissions are ticking up only slightly—with admissions rising to about 8,000 in the week of July 22, up from around 6,300 the week of June 24.

Local and federal authorities have shut down what seems to be an illegal medical lab hidden in a California warehouse that contained nearly 1,000 laboratory mice, hundreds of unknown chemicals, refrigerators and freezers, vials of biohazardous materials, including blood, incubators, and at least 20 infectious agents, including SARS-CoV-2, HIV, and a herpes virus.

According to NBC News affiliate KSEE of Fresno , local authorities were first tipped off to the unlicensed facility when a local code enforcement officer noticed that a garden hose was illegally attached to the back of the building. That led city officials to obtain a search warrant to inspect the warehouse, which was supposed to only be used for storage.

According to court documents obtained by NBC News , city officials inspected the warehouse, located in Reedley, southeast of Fresno, on March 3. County health officials then inspected the facility on March 16. What they found reportedly shocked them.

For the second time, contaminated bone graft products from the medical company Aziyo Biologics Inc. are linked to a highly unusual and deadly outbreak of tuberculosis .

This week, three new tuberculosis cases were identified, bringing the outbreak total to five, according to Politico . One person has died. The contaminated material, used for surgical and dental procedures, was implanted in at least 36 other patients, who are now being treated as if they have tuberculosis.

Aziyo Biologics issued a recall of all of its bone matrix products earlier this month "out of an abundance of caution" after the first two cases were identified. The Centers for Disease Control and Prevention reports that all unused products from the affected lot have been sequestered so that they will not be used. The affected materials had been sent to health care facilities in California, Michigan, New York, Oregon, Texas, and Virginia.

A little over a decade ago, researchers discovered that bites from lone star ticks could cause some people to develop a food allergy to meat and meat products —an allergic condition called alpha-gal syndrome (AGS) , which can vary from mild to life-threatening.

The condition is named after a carbohydrate called galactose-α-1,3-galactose (aka alpha-gal), which is commonly found on proteins in most mammals—with the important exception of primates, like humans. Alpha-gal shows up on all sorts of non-primate mammalian tissue, which means it's also in meat—such as pork, beef, rabbit, and lamb—and animal products, like milk and gelatin. Its presence on animal tissue is one of the big, long-recognized barriers to xenotransplantation—that is, transplanting pig hearts into people, for example. Human immune systems will, in part, reject the organ because of the presence of the foreign alpha-gal.

But, in recent years, researchers have also discovered that alpha-gal is in tick saliva . And, for reasons researchers still haven't worked out, some people bitten by ticks develop a type of antibody called anti-alpha-gal IgE . This antibody may help protect people from tick bites but also renders them allergic to anything with alpha-gal—i.e., mammalian meat and animal products. It's a double-edged sword that's been hypothesized to be an " allergic klendusity ."
