Cyclospora Outbreak Update"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\"><strong>Short answer: yes, for most people, most lettuce is safe to eat again \u2014 but the outbreak isn&#8217;t fully closed, and the science took a confusing turn.<\/strong> The one lab test that directly confirmed Cyclospora in a Taylor Farms lettuce sample was retracted five days later as a false positive. As of the latest CDC and FDA updates, no product sample has tested positive for the parasite. Yet the case count has grown to 1,947 illnesses across nine states, and Taylor Farms has still pulled every bag of lettuce tied to the implicated Mexican farm. Here&#8217;s what that actually means for your fridge and your next taco.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quick facts, updated:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The lab result confirming Cyclospora in lettuce was retracted.<\/strong> The FDA now says the July 18 &#8220;positive&#8221; sample was a false positive and does not represent a true finding<\/li>\n\n\n\n<li><strong>No product sample has tested positive for Cyclospora<\/strong> as of the most recent FDA and Taylor Farms updates \u2014 the case still rests on patient interviews and traceback data, not a confirmed lab match<\/li>\n\n\n\n<li><strong>The outbreak has grown to 1,947 illnesses across 9 states<\/strong>, with 98 hospitalizations and no deaths reported<\/li>\n\n\n\n<li><strong>Taylor Farms has stopped sourcing iceberg lettuce from central Mexico for the rest of the growing season<\/strong> and says the recalled product has been removed from the marketplace<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The Big Update: The Positive Lab Test Was Retracted<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On July 18, 2026, the FDA announced that a Taylor Farms shredded iceberg lettuce sample had tested positive for Cyclospora in laboratory testing \u2014 the first direct physical confirmation of the parasite in the implicated product, rather than just an epidemiological link. That changed almost immediately. As <a href=\"https:\/\/www.cnn.com\/2026\/07\/18\/health\/cyclospora-taylor-farms-lettuce-recall\" target=\"_blank\" rel=\"noopener\">CNN reported<\/a>, the FDA re-reviewed the result on July 19\u201320 and walked it back, saying the finding did not represent true amplification and should be treated as a false positive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to <a href=\"https:\/\/www.npr.org\/2026\/07\/20\/nx-s1-5901356\/fda-focused-taylor-farms-lettuce-cyclospora-source-despite-retracted-test\" target=\"_blank\" rel=\"noopener\">NPR&#8217;s coverage<\/a>, Taylor Farms said the FDA apologized for the error and emphasized that, to date, the agency has not identified a single confirmed positive product test result for Cyclospora. That leaves investigators back where they were before July 18: relying on patient interviews and a supply-chain traceback rather than a lab-confirmed source. It&#8217;s a reminder that Cyclospora is notoriously difficult to detect directly in food, even when the epidemiological evidence pointing at a product is strong.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">So Why Is Lettuce Still Being Blamed?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because the traceback and interview evidence hasn&#8217;t changed, even though the lab test did. Per <a href=\"https:\/\/www.npr.org\/2026\/07\/17\/nx-s1-5897509\/lettuce-taco-bell-mexico-cyclospora-outbreak\" target=\"_blank\" rel=\"noopener\">NPR&#8217;s reporting<\/a>, Michigan health officials interviewed roughly 190 people who got sick after eating at Taco Bell, and 90% of them reported eating iceberg lettuce. Combined with an FDA supply-chain traceback that converged on a single supplier \u2014 Taylor Farms de Mexico, sourcing from one central-Mexico farm that represents less than 1% of the U.S. iceberg lettuce supply \u2014 that&#8217;s still considered strong evidence, just not a laboratory-confirmed one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taylor Farms itself has kept the recall and sourcing suspension in place despite the retracted test, which tells you the company isn&#8217;t treating the false positive as an all-clear either.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where the Outbreak Stands Now<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Metric<\/th><th>Latest Figure<\/th><\/tr><\/thead><tbody><tr><td>Confirmed illnesses linked to Taco Bell exposure<\/td><td>1,947 across 9 states<\/td><\/tr><tr><td>States now included<\/td><td>Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania, West Virginia<\/td><\/tr><tr><td>Hospitalizations<\/td><td>At least 98; no deaths reported<\/td><\/tr><tr><td>Illness onset window<\/td><td>June 22 \u2013 July 20, 2026<\/td><\/tr><tr><td>Confirmed positive product samples<\/td><td>Zero, after the July 18 result was retracted<\/td><\/tr><tr><td>Taylor Farms sourcing status<\/td><td>Suspended for central Mexico for the remainder of the season<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Figures from the <a href=\"https:\/\/www.cdc.gov\/cyclosporiasis\/outbreaks\/07-26\/investigation.html\" target=\"_blank\" rel=\"noopener\">CDC&#8217;s Cyclospora outbreak investigation page<\/a>, the <a href=\"https:\/\/www.fda.gov\/food\/outbreaks-foodborne-illness\/investigation-9-state-outbreak-cyclospora-illnesses-iceberg-lettuce-july-2026\" target=\"_blank\" rel=\"noopener\">FDA&#8217;s outbreak investigation page<\/a>, and <a href=\"https:\/\/www.taylorfarms.com\/newsroom\/taylor-fresh-foods-statement-regarding-cyclospora-outbreak\/\" target=\"_blank\" rel=\"noopener\">Taylor Farms&#8217; public statement<\/a>, current as of late July 2026 and subject to change.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is It Safe to Eat Lettuce Right Now?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For the vast majority of lettuce on shelves today, yes. The specific product tied to this outbreak \u2014 shredded iceberg lettuce from one central-Mexico farm supplying Taylor Farms de Mexico \u2014 has been recalled, pulled from the market, and Taylor Farms says it&#8217;s no longer sourcing from that region for the rest of the season. Regular lettuce from other suppliers, other regions, and other brands was never implicated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That said, a few practical points are worth knowing before you relax completely:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Check for recalled Marketside products.<\/strong> If you still have Marketside iceberg salad or shredded lettuce (12-oz\/24-oz salad bags, 8-oz\/16-oz shredded bags) with a best-if-used-by date between July 18 and August 3, 2026, throw it out or return it \u2014 don&#8217;t eat it, retracted lab test or not<\/li>\n\n\n\n<li><strong>The investigation isn&#8217;t officially closed.<\/strong> Case counts have grown as recently as late July, and the FDA has said additional states or products could still be added<\/li>\n\n\n\n<li><strong>Cyclospora is killed by heat, not by rinsing alone.<\/strong> Health officials note that cooking produce to around 158\u00b0F inactivates the parasite; washing reduces but doesn&#8217;t eliminate risk on produce that will be eaten raw<\/li>\n\n\n\n<li><strong>Symptoms can take up to six weeks to link back to an outbreak<\/strong>, so new cases tied to lettuce eaten weeks ago may still surface even as fresh product is considered safe<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What About Taco Bell?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Taco Bell says it stopped using lettuce from Taylor Farms de Mexico as of July 17, 2026, and removed the ingredient from its supply chain nationwide, according to the <a href=\"https:\/\/www.fda.gov\/food\/outbreaks-foodborne-illness\/investigation-9-state-outbreak-cyclospora-illnesses-iceberg-lettuce-july-2026\" target=\"_blank\" rel=\"noopener\">FDA&#8217;s investigation update<\/a>. The company has publicly framed food safety as a shared responsibility between restaurants, suppliers, and regulators, and has encouraged franchisees and retailers to take the same precautions, per its statement to <a href=\"https:\/\/www.cbsnews.com\/news\/cyclosporiasis-outbreak-taco-bell-lettuce-mexico\/\" target=\"_blank\" rel=\"noopener\">CBS News<\/a>. No other Taco Bell menu items have been implicated \u2014 this outbreak has only ever been tied to the shredded iceberg lettuce itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms to Watch For<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cyclosporiasis, caused by the parasite <em>Cyclospora cayetanensis<\/em>, typically starts about a week after exposure and can include sudden watery diarrhea, loss of appetite, cramping, bloating, fatigue, and occasionally a low-grade fever. It&#8217;s rarely life-threatening, but without treatment symptoms can persist for weeks and even relapse. If you ate at an affected Taco Bell or had recalled lettuce at home in the past several weeks and are still experiencing persistent watery diarrhea, see a doctor and specifically ask about Cyclospora testing \u2014 routine stool tests can miss it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is lettuce safe to eat now that the positive test was retracted?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Regular lettuce from unaffected suppliers is safe. The specific recalled product from Taylor Farms de Mexico&#8217;s central-Mexico farm should still be avoided or discarded if you have it, since the recall remains in place despite the retracted lab result.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Did the FDA ever confirm Cyclospora in a lettuce sample?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Briefly, yes \u2014 for about a day. The July 18 announcement was retracted on July 19\u201320 as a false positive. As of the latest updates, no product sample has tested positive for the parasite.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How many people have gotten sick in total?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At least 1,947 people across nine states have been linked to the Taco Bell cluster specifically, with 98 hospitalizations and no deaths reported.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is Taylor Farms still selling lettuce from Mexico?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. Taylor Farms says it has voluntarily suspended sourcing and production of iceberg lettuce from central Mexico for the remainder of the growing season.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What should I do if I still have recalled lettuce at home?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Throw it out or return it to the store for a refund. Also clean and sanitize any surfaces or containers it touched to avoid cross-contamination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The upshot: the outbreak&#8217;s headline lab evidence didn&#8217;t hold up, but the traceback case against the lettuce still stands, the recall is still active, and Taylor Farms still isn&#8217;t sourcing from the implicated region. For most people, eating lettuce today is safe \u2014 just not the specific recalled bags still sitting in some fridges.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Disclaimer: This article is for general information only and is not a substitute for medical advice, diagnosis, or treatment.
