1. Nationwide Recall of Clear Eyes Itchy Eye Relief Drops
Clear Eyes issued a nationwide recall of its Maximum Itchy Eye Relief drops after a sterility assurance failure was identified during routine testing[1]. The FDA classified the action as a Class II recall, and the recall covers roughly 39,000 bottles distributed across the country[2]. As of Aug. 27, 2026, the FDA's public notice describes the concern as a potential rather than confirmed contamination issue, and no eye infections had been formally linked to the affected lots at that time[3]. Because eye drops are applied directly to a mucous membrane, a sterility failure of this kind carries a real infection risk if it did occur — a concern that's greater for people with compromised immune systems or existing eye conditions[4].

※ If you've used this product recently and notice new eye redness, pain, discharge, or vision changes, seek medical care promptly.
Why it matters: The only reliable way to know if you're affected is to check the product name and lot number against the FDA's official recall notice — assuming your bottle is fine (or assuming it isn't) without checking isn't a safe bet either way.
2. Nationwide Recall of Everything Sprouts and Calco Alfalfa Sprouts
Everything Sprouts and Calco issued a voluntary recall on Aug. 22, 2026, of alfalfa sprouts and several sprout-based products — including Crunchy Protein Sprout Mix and Zesty Garlic Mix cups — after the products were linked to an FDA outbreak investigation into Shiga toxin-producing E. coli and Salmonella illnesses[1]. The recall applies to specific lot numbers 222, 223, 225, 226, and 230, and affected products were distributed to retailers in at least 15 states[2]. As of Aug. 29, 2026, the FDA's outbreak investigation has tied the recall to 55 illnesses and 4 hospitalizations, and the agency has not yet published a finalized case count while the investigation remains open[3]. Raw sprouts are grown in warm, humid conditions that can favor bacterial growth and are typically eaten uncooked, which is why public health officials have long treated them as a higher-risk food category for young children, older adults, pregnant women, and anyone with a weakened immune system[3].

※ If you have any of the recalled sprout products, do not eat them — discard or return them, and contact a healthcare provider if you develop symptoms such as bloody diarrhea, fever, or vomiting after eating sprouts.
Why it matters: Check your kitchen against the specific lot numbers in the FDA's recall notice — contaminated sprouts don't necessarily look, smell, or taste different, so appearance alone can't tell you whether a package is affected.
3. Waist Size May Add to What BMI Misses in Adults 65 and Older
A study following nearly 7,000 adults ages 65 and older for as long as 14 years found that waist circumference added meaningful predictive information beyond body mass index alone[1]. Researchers behind the analysis reported that BMI can look "normal" even in older adults who carry a higher share of visceral fat around the abdomen, a pattern more closely tied to cardiovascular and metabolic risk than total body weight[2]. The findings add to a growing body of research questioning BMI as a stand-alone health metric — a limitation that matters especially for older adults, since age-related muscle loss can mask fat gain on a bathroom scale[3].

[2] AJMC, "Waist size, not just weight, predicts mortality risk in older adults" (2026)
[3] Johns Hopkins Medicine, "Sarcopenia, Body Mass Index and Adults Age 65-Plus"
Why it matters: If you're in this age group and your BMI reads as "normal," that alone doesn't rule out cardiometabolic risk — a waist measurement is a low-cost data point worth raising with your healthcare provider, though it isn't a diagnostic tool by itself.
4. FDA Approves Updated COVID-19 Vaccine, Prioritizing Older and High-Risk Adults
Last week's digest noted a summer COVID-19 resurgence with positivity rates near 3.8% for the week of Aug. 8; that upward trend has continued into this week, with positivity climbing further to roughly 4.8%-5% in the days spanning Aug. 13-15[1]. Against that backdrop, the FDA approved an updated COVID-19 vaccine formulation on Aug. 27, 2026, targeting the strain currently in circulation[2]. The approval prioritizes rollout to adults 65 and older, people with underlying health conditions, and other groups at elevated risk of severe illness, with broader availability expected to follow as supply expands[3]. This mirrors the approach taken with the mRNA flu vaccine approved earlier this month for adults 65 and older, which similarly opened access to higher-risk groups before a general rollout[4].

[3] Pfizer, "Pfizer and BioNTech Receive US FDA Approval for XFG-Adapted COVID-19 Vaccine" (2026)
[4] "mRNA Flu Vaccine for Adults 65+: What FDA Approval Means" (2026)
Why it matters: If you're in a priority group, it's reasonable to check with your pharmacy or provider about availability now rather than waiting for a broader announcement — supply for a newly approved vaccine formulation is typically staggered, not instantly available everywhere at once.
5. About a Third of US Adults Now Use AI Chatbots for Health Questions
A Pew Research Center survey published Aug. 25, 2026, found that about 34% of US adults say they've used an AI chatbot to look up health-related information[1], a figure quickly picked up by outlets including Becker's Hospital Review in the days since. The survey's authors noted that people most often use these tools for quick answers about symptoms, medications, or general wellness questions rather than as a substitute for seeing a doctor[2]. The trend fits a broader pattern of the past several years — search engines and symptom checkers have each, in turn, become an early stop before (or instead of) a clinic visit, and conversational AI is simply the newest version of that habit. That popularity doesn't make the underlying advice inherently reliable: chatbots can produce confident-sounding answers that are incomplete or wrong, and they can't examine you or know your full medical history[3].
[1] Pew Research Center, "From Diagnoses to Treatments: Why Americans Use AI Chatbots for Health" (2026)
[2] Becker's Hospital Review, "34% of Americans use AI chatbots for health, report finds" (2026)
[3] Pew Research Center, "Users of Social Media and AI Chatbots for Health Information Are More Likely To Say They Are Convenient Than Accurate" (2026)
Why it matters: Using a chatbot to understand a term or prepare questions for a doctor is a reasonably low-stakes use; using one to decide whether a symptom is serious enough to skip a medical visit is where the convenience starts to carry real risk.
💡 This Week's Top Questions, Answered
Q. How do I check if my eye drops are part of the Clear Eyes recall, and what should I do with them?
Look up the product name, lot number, and expiration date printed on your bottle against the list in the FDA's official recall notice for Clear Eyes Maximum Itchy Eye Relief, since not every lot or Clear Eyes product is affected[1]. If your bottle matches, stop using it and contact the retailer or manufacturer for return or refund instructions rather than simply throwing it away, as recall notices sometimes include specific reporting steps. The safest approach is to confirm the exact lot number against the FDA list rather than assuming the recall does or doesn't apply based on the product name alone. If you've already used the product without symptoms, discontinuing use is generally sufficient, but contact a healthcare provider if any eye symptoms develop.

Q. I bought Everything Sprouts alfalfa sprouts, but the lot number on the package isn't one of the five listed in the recall. Does that mean I'm in the clear?
Not automatically. Recall lists can expand as investigators trace more retail and distribution records, so a lot number that isn't flagged today could still be added later — it's worth checking the FDA's recall page periodically rather than treating an unlisted lot as a one-time clearance. It also helps to watch for symptoms regardless of lot number, since Salmonella symptoms can begin within hours to about six days after exposure, while E. coli symptoms typically start three to four days later but can take up to 10 days to appear[1], including diarrhea, cramping, or fever. If those symptoms develop, especially in young children or older adults, it's best to contact a healthcare provider rather than try to self-diagnose based on packaging details alone.
[1] CDC, "Symptoms of Salmonella Infection"; CDC, "Symptoms of E. coli Infection"
Q. I'm over 65 and my BMI is normal — is it still worth measuring my own waist circumference?
General guidelines have long used a waist circumference above roughly 40 inches for men and 35 inches for women as one marker of elevated health risk, though these thresholds were developed mainly in general adult populations rather than specifically for older adults[1]. Measuring your own waist at home with a tape measure, at the level of your navel, can give you a rough data point worth bringing to a healthcare provider. A single waist measurement can't tell you your actual mortality risk or substitute for a broader health evaluation. Treat the number as a conversation starter at your next checkup, not a self-diagnosis.

Q. Will I have to pay out of pocket for the updated COVID-19 vaccine, and when will it reach my local pharmacy?
Coverage has typically mirrored how earlier COVID-19 vaccine updates were handled: most private insurance plans, Medicare, and Medicaid have covered recommended COVID-19 vaccines with no out-of-pocket cost once a formulation is approved and officially recommended, though details can vary by plan[1]. Availability at individual pharmacies tends to lag the federal approval by days to a few weeks while distributors ship the new formulation and pharmacies update their systems[1]. Calling ahead to your pharmacy or checking your insurer's vaccine coverage page is more reliable than assuming national approval means immediate, free access everywhere.
[1] KFF Health News, "Health Insurers Will Cover All Vaccines Through 2026 With No Cost-Sharing" (2026)
Q. Is it actually riskier to use an AI chatbot for health questions than to just search online?
The underlying risk is fairly similar to searching online for symptoms — both can surface inaccurate or out-of-context information — but chatbots tend to present answers in a more confident, conversational tone that can make incorrect information feel more authoritative than a plain list of search results would[1]. Neither a chatbot nor a search engine can examine you, order tests, or account for your full medical history, which is what an actual clinical evaluation is for. Using either tool to prepare questions for an upcoming appointment is a reasonably safe use; using either to rule out a serious symptom on your own carries more risk.

👀 What We're Watching
"Fibermaxxing" High-Fiber Diet Trend
Mayo Clinic Press has published consumer-facing guidance explaining "fibermaxxing" — a social-media-driven push to eat well beyond the fiber amount most Americans typically get — including cautions that ramping up fiber intake too quickly can cause digestive discomfort, and broadcast outlet WWLP has separately reported on experts urging caution around the trend[1]. Two independent outlets — a mainstream medical institution and a news broadcaster — have each found the trend significant enough to address directly.
Why we're watching: More than one type of outlet has found the trend worth addressing directly with consumer guidance and expert caution, rather than a single outlet's passing mention.
