CDC said grocery store lettuce is not affected. @YourTaylorFarms posts 7/17/26 that their branded salads and kits are not affected. But, then Taylor Farms' own recall lists consumer retail bags 7/18/26. 👉 We need clear warnings if this is a danger to the public.

27 states got recalled Taylor Farms lettuce: AL, AR, CT, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, MS, NC, NH, NJ, OH, OK, PA, SC, TN, TX, VA, WI. Distribution ran June 29 to July 16, with use by dates into early August.

Taco Bell acted before Taylor Farms or FDA did. It pulled the implicated lettuce nationwide on July 17, a day ahead of Taylor Farms posting its own 27 state recall. 👉Taco Bell outpaced the supplier and the US regulator by a day.

Taylor Farms recalled lettuce tied to a Cyclospora outbreak. It listed customer brands as cryptic codes instead of real names. Attorney Bill Marler decoded them: 🔹SY is Sysco 🔹MKTSD is Walmart's Marketside 👉 This recall touches grocery stores, not just restaurants. 🧵 #medsky #publichealth

DOGE downsized CDC's Cyclospora lab last year. buff.ly/5OmTvIc Now a record Cyclospora outbreak from lettuce has hit Taco Bell in 5 states. buff.ly/UMvzdTs Maybe defunding the people who track foodborne illness wasn't such a good idea. ¯\_(ツ)_/¯ #medsky #IDsky

I was just trying to look up a place to get a COVID booster on Vaccines.gov and it appears that the site is not working. Does anyone know how long the CDC's site has been down for "updates"??? #medsky #publichealth

A study of 173 hospitalized COVID patients found "leaky gut" biomarkers track with severe inflammation. When the gut barrier breaks down, bacterial products enter the blood, driving worse outcomes. 👉Healing the gut may be an overlooked step in acute viral care. buff.ly/oNnVEkk #MedSky #IDSky

My first thought was, who is the conductor in the picture? The virus? How about something like this if the book is about viral persistence in Long COVID.

Simoa® assay data over 2 years: 🔹 At 6-12 months: Viral antigens were found in 31% of Long COVID patients vs 20% of fully recovered vs 5% of never infected people. 🔹 By 18-24 months: Detection dropped to nearly 0% across the board. 🔹 No link found between blood antigens & symptom severity. 2/3

Long COVID 31% in Red, V2 was 3.5%
Recovered 20% in green, V2 was 0%
Uninfected 5.4% in yellow, V2 was 1.5%

Can a simple blood test for viral proteins diagnose Long COVID? A new 2-year blinded study from Spain tracked 425 adults and found that SARS-CoV-2 antigens in the blood clear out by year 2 for almost everyone regardless of recovery status. 🧵1/3
