A major food recall has expanded this week, while the nation’s top health official quietly launches a sweeping investigation into vaccine safety. Meanwhile, scientists continue to debate whether a popular anti-aging supplement actually works. Here is a breakdown of the week’s most important health news and what it means for you.

Spring & Mulberry Chocolate Bars Recalled Over Salmonella Risk

Spring & Mulberry has voluntarily expanded its recall of certain chocolate bars due to possible Salmonella contamination, according to a notice posted by the U.S. Food and Drug Administration (FDA).

The company first announced a limited recall earlier this month but has now widened the scope to include additional products. Consumers who have purchased these chocolate bars should check the lot numbers and expiration dates listed on the FDA’s website.

Why this matters to you: Salmonella infection can cause serious illness, especially in young children, older adults, and people with weakened immune systems. Symptoms typically include diarrhea, fever, and stomach cramps that appear 6 hours to 6 days after eating contaminated food. Most people recover without treatment within 4 to 7 days, but some cases require hospitalization.

Health experts recommend that anyone who has purchased recalled chocolate bars should throw them away immediately or return them to the store where they were bought. Do not taste-test the chocolate to see if it is safe, as Salmonella cannot be detected by smell or appearance.

The FDA continues to monitor the situation and may update the recall list as more information becomes available.

RFK Jr. Quietly Expands Vaccine Investigation Despite Softer Public Tone

Health and Human Services Secretary Robert F. Kennedy Jr. has publicly softened his criticism of vaccines in recent weeks, but behind the scenes, he is driving a massive inquiry into whether vaccines are linked to neurological and autoimmune diseases, according to a report from the New York Times.

The investigation, described by sources as “vast” in scope, is examining potential connections between routine childhood vaccines and conditions such as autism, multiple sclerosis, and chronic fatigue syndrome. Kennedy has long been a controversial figure in public health due to his history of questioning vaccine safety.

What experts say: The overwhelming consensus among mainstream medical organizations, including the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the World Health Organization, is that vaccines are safe and effective. Decades of research involving millions of patients have found no credible link between vaccines and autism or other chronic neurological conditions.

However, experts acknowledge that vaccine safety monitoring is an ongoing process. The CDC and FDA operate the Vaccine Adverse Event Reporting System (VAERS), which allows anyone to report potential side effects. This system is designed to detect rare or unexpected problems that may not appear in clinical trials.

Many public health officials worry that the current investigation, if not handled carefully, could undermine public confidence in vaccines at a time when measles outbreaks are rising across the United States.

FDA Commissioner Marty Makary Continues Work Despite White House Plans to Remove Him

FDA Commissioner Dr. Marty Makary has maintained his public schedule this week, including speaking engagements, despite reports that the White House is planning to remove him from his position, according to Politico.

Makary, a surgeon and health policy expert, was appointed earlier this year. His tenure has been marked by efforts to speed up drug approvals and reduce regulatory burdens. The apparent conflict between the commissioner and the White House has created uncertainty within the agency.

Industry observers say that leadership instability at the FDA can slow down drug reviews, delay food safety actions, and confuse the public about who is in charge of protecting the nation’s food and medical supply.

Dutch Hospital Quarantines 12 Staff After Hantavirus Protocol Breach

A hospital in the Netherlands has placed 12 staff members in quarantine after they violated safety protocols while handling blood and urine from a patient infected with hantavirus, Reuters reports.

Hantavirus is a rare but serious virus spread by rodents. Infection can cause hantavirus pulmonary syndrome, which starts with flu-like symptoms and can quickly progress to severe breathing difficulties. The virus is not spread from person to person under normal circumstances, but healthcare workers handling contaminated bodily fluids are at higher risk.

The quarantine is a precautionary measure to monitor the staff for any signs of infection. If any develop symptoms, they can receive immediate medical care.

AI Companies Face New Lawsuit Over Copyrighted Medical Research

Scientific publisher Elsevier has joined dozens of companies and individuals in suing artificial intelligence companies over the alleged use of copyrighted research papers to train AI models, according to Nature.

The lawsuit claims that AI companies have been feeding medical journals, textbooks, and research articles into their systems without permission or payment. This is part of a broader legal battle over whether AI companies can freely use copyrighted material to build their products.

For readers, this matters because AI tools used in healthcare, such as diagnostic algorithms or drug discovery programs, rely heavily on training data from published medical research. If courts rule that this use is illegal, it could slow the development of AI-powered medical tools.

Supreme Court Extends Pause on Abortion Pill Mail Restrictions

The U.S. Supreme Court has extended a temporary pause on a lower court ruling, meaning that abortion pills can continue to be available by mail at least through Thursday, according to The Hill.

The case involves mifepristone, a medication used in more than half of all U.S. abortions. Anti-abortion groups had sued to restrict access to the drug, including ending the ability to receive it through the mail. The Supreme Court’s temporary order keeps the current rules in place while the case continues.

For patients, this means that telemedicine appointments for medication abortion remain legal in states where abortion is permitted. However, the situation remains fluid, and patients are advised to check their state’s current laws.

Measles Cases Rise: 49 New Infections Reported in Past Week

The United States has reported 49 new measles cases in the past week, according to data from the Yale School of Public Health. The cases are spread across multiple states, though specific locations were not detailed in the report.

Measles is a highly contagious virus that can cause serious complications, including pneumonia, encephalitis (brain swelling), and death. The disease was declared eliminated in the U.S. in 2000, but declining vaccination rates have led to outbreaks in recent years.

Public health officials emphasize that the measles, mumps, and rubella (MMR) vaccine is 97% effective after two doses and is the best protection against the disease.

Scientists Warn Congress: NSF Cuts Could Harm U.S. Competitiveness

More than 2,500 scientists have signed a letter to Congress warning that President Trump’s dismissal of the National Science Foundation’s oversight board represents an “alarming attack” on research funding, according to the New York Times.

The letter argues that cutting NSF funding could place the United States at a competitive disadvantage compared to rivals like China. The NSF funds basic research in medicine, engineering, and technology that often leads to breakthroughs in healthcare and other fields.

For patients, this means that future medical advances, from new cancer treatments to better diagnostic tools, could be delayed if research funding is reduced.

Kratom Products Recalled: Better Weather Fix Elixir Pulled from Shelves

XD Investments is recalling all Better Weather Fix Elixir products due to the presence of undeclared mitragynine (kratom) and mitragynine pseudoindoxyl, according to an FDA notice.

Kratom is a plant-based substance that some people use for pain relief or energy, but it is not approved by the FDA for any medical use. The agency has warned that kratom can cause addiction, liver damage, and serious side effects including seizures and death.

Consumers who have purchased this product should stop using it immediately and contact their healthcare provider if they experience any adverse effects.

FDA Seeks Public Input on Drug Repurposing for Unmet Medical Needs

The FDA has announced that it is soliciting input from the public on drug repurposing efforts. Drug repurposing involves finding new uses for existing medications that are already approved for other conditions.

This approach can be faster and cheaper than developing entirely new drugs because the safety profiles of existing medications are already known. The FDA is specifically interested in ideas for treating rare diseases and conditions where no effective treatments currently exist.

Patients and researchers can submit comments through the FDA’s website during the public comment period.

Can NAD+ Supplements Really Boost Longevity? A Look at the Evidence

Nicotinamide adenine dinucleotide, better known as NAD+, has become a popular anti-aging supplement. But does the science support the hype? NPR recently examined the evidence.

NAD+ is a coenzyme found in every cell of the body. It plays a critical role in energy production and DNA repair. Levels of NAD+ naturally decline as we age, leading some researchers to believe that boosting these levels could slow the aging process.

What the research shows:

• Animal studies have shown that increasing NAD+ levels can improve metabolism, protect against nerve damage, and extend lifespan in mice.
• Human studies are much more limited. Small trials have found that NAD+ precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) can raise NAD+ levels in the blood.
• However, no large, long-term human study has proven that NAD+ supplements actually extend human lifespan or prevent age-related diseases.

Experts caution that the supplement market is poorly regulated. Products claiming to contain NAD+ or its precursors may not contain the amounts listed on the label, and some may contain contaminants.

Practical takeaway for readers: While the science is promising, there is not enough evidence yet to recommend NAD+ supplements for longevity. Eating a healthy diet, getting regular exercise, and avoiding smoking are proven ways to support healthy aging without the cost or uncertainty of supplements.

New Study: Cardiac MRI and Blood Test Predict Outcomes in Heart Disease

Findings from a registry study published in JAMA provide evidence that combining cardiac magnetic resonance (CMR) imaging with NT-proBNP blood testing can help predict outcomes in patients with hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy is a condition where the heart muscle becomes abnormally thick, making it harder for the heart to pump blood. It affects about 1 in 500 people and is a leading cause of sudden cardiac arrest in young athletes.

The study suggests that using both tests together gives doctors a more accurate picture of a patient’s risk than either test alone. This could help doctors decide which patients need more aggressive treatment, such as implantable defibrillators, and which can be managed with medication alone.

Charity Care at Hospitals May Be Harder to Find as Uninsured Numbers Grow

A new report from NPR highlights that charity care, which is free or discounted medical care provided by hospitals to low-income patients, may be harder to obtain as the number of uninsured Americans grows.

Hospitals are required by law to provide some charity care in exchange for their tax-exempt status, but many patients report difficulty navigating the application process. Some hospitals have also been accused of aggressive billing practices against uninsured patients.

Patients who need financial assistance should ask their hospital about charity care programs, apply in writing, and keep copies of all documents. Many hospitals also offer payment plans for those who do not qualify for full charity care.

Rethinking Suicide Prevention: Lowering Cost of Living May Help

Decades of research point to a new approach to suicide prevention: lowering the cost of living, according to a report from KFF Health News.

Traditional suicide prevention focuses on mental health treatment and crisis hotlines. While these remain important, researchers have found that financial stress, housing instability, and lack of access to basic needs are major risk factors for suicide.

Policy changes such as affordable housing initiatives, expanded health insurance coverage, and higher minimum wages could potentially reduce suicide rates more effectively than clinical interventions alone, experts argue.

Houston Hospital Employee Stabbed in Parking Garage, Expected to Recover

Police continue to investigate after a Houston Methodist employee was stabbed inside a parking garage at the Texas Medical Center, according to KPRC Houston. The employee was recovering in the hospital and expected to be released soon.

Hospital security has been increased in the area, and officials are urging anyone with information about the attack to come forward. Workplace violence in healthcare settings is a growing concern, with many hospitals implementing new safety protocols.

Tennessee Doctor Limits Embryo Creation Based on Christian Faith

A Tennessee doctor has aligned his reproductive medicine practice with his Christian faith, according to the Associated Press. The doctor limits how many embryos his clinic creates during in vitro fertilization (IVF), does not discard viable embryos, and does not genetically test embryos or donate them to science.

This approach reflects a growing trend among some religious healthcare providers who seek to practice medicine in accordance with their moral beliefs. For patients, this means that access to certain fertility treatments may vary depending on where they live and which doctors they see.
