Apocryphal tales of its meals causing the runs have plagued Taco Bell since time immemorial. But this latest parasitic outbreak is something else entirely.
As the Washington Post reports, federal and state authorities are investigating whether the fast food chain is behind the outbreak of explosive diarrhea cases across the country — further cementing its scatological legacy.
The illness, caused by the cyclosporiasis parasite, has sickened as many as 5,100 people across the country, according to the Centers for Disease Control and Prevention. In Michigan, which appears to be the epicenter of the outbreak, over 3,700 people have been infected, state authorities said.
Taco Bell’s suspected role in the outbreak comes after reports that the chain’s Michigan locations began pulling some of its ingredients. Signs in front of the restaurants stated that they were no longer serving lettuce, cilantro, onion, pico de gallo, and guacamole due to a “nationwide recall,” though what recall they were referring to is unclear.
Health officials have so far struggled to narrow down how the parasite is spreading. While usually found on fresh produce, symptoms can take weeks to manifest, making it difficult to trace back to the source.
Lettuce has emerged as one of the likeliest culprits. In an update this week, Michigan’s chief medical executive Natasha Bagdasarian said that “early information has shown lettuce as a common product that regularly comes up during the investigation.”
“Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families,” Bagdasarian added.
Federal authorities haven’t singled out any veggies yet, though acting Food and Drug Administration director Don Prater acknowledged Michigan’s fixation on lettuce.
“What I can say at this point is that we’re continuing our traceback investigation on multiple produce items, including the lettuce,” he said, per WaPo.
So far, no nationwide recalls have been made related to the outbreak. One person familiar with the federal investigation, however, praised Taco Bell’s response.
“It’s good the chain has already voluntarily stopped serving a number of items,” they told the newspaper. They added that some who became sick said they didn’t eat at the chain, suggesting that it’s not the only one responsible.

In Israel’s Qafzeh cave, archaeologists have discovered an intriguing set of ancient human remains that reveal a story of illness, violence, death, and survival in the remote past.
The international team of archaeologists from Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) and Tel Aviv University revealed their analysis of ancient human fossil remains, known as Qafzeh 25, in a recent paper published in Scientific Reports.
The findings provide rare evidence of interpersonal violence, care for the injured, and early funerary practices in a human population that lived between 92,000 and 145,000 years ago.
The researchers used a range of techniques to examine one particularly intriguing skull, including high-resolution micro-computed tomography (microCT) alongside macroscopic and microscopic analyses. Their investigation revealed a linear lesion across the mandible and lower premolars, with characteristics consistent with trauma inflicted by a sharp object.
Despite the severity of the injury, the researchers concluded that the individual survived the ordeal based on evidence of bone remodeling. The extent of healing suggests the person lived for a considerable period after suffering the wound.
Although the available evidence does not allow archaeologists to determine exactly how the injury occurred, they consider interpersonal violence the most likely explanation. The discovery is particularly significant because evidence of sharp-force trauma in Middle Paleolithic human remains is exceedingly rare.
Beyond the apparent head injury, the Qafzeh 25 skull yielded another remarkable discovery. Detailed examination of the teeth revealed dental conditions that had not previously been documented in humans of this antiquity.
The microCT scan revealed a hidden carious lesion in a lower premolar, along with enamel defects. These sorts of tooth decay issues are uncommon in early homo sapiens, as they are largely caused by bacteria that thrive on sugars. Before the advent of agriculture and later processed carbohydrates and refined sugars, such tooth decay was rare due to diets high in meats, nuts, and fibrous vegetables, which helped clean the teeth.
Looking beyond the skull, the researchers also examined the broader funerary context of the skeleton in an effort to reconstruct the burial practices of these ancient humans.
A broader analysis of the entire skeleton suggests it was deliberately buried, as it lacks evidence of carnivore predation or damage consistent with exposure to the elements. According to the researchers, this makes Qafzeh Cave one of the most important sites in the world for studying Homo sapiens’ earliest internment practices and the relationship not just between the living and the dead, but also between the living and the dying.
“These findings provide new evidence in the ongoing debate about the origins of complex behaviours such as interpersonal violence, the care of injured or ill individuals, and funerary practices—fundamental aspects for understanding the social and cultural evolution of our species,” said lead author Ana Pantoja Pérez, a member of the DEATHREVOL research group.
The find represents one of the earliest known well-preserved human populations outside of Africa at this time, residing in the Levant at least 90,000 years ago. With evidence of a healed traumatic injury, unusual dental disease, and intentional burial, the Qafzeh 25 skeleton offers a rare glimpse into the lives—and deaths—of some of our earliest ancestors.
The paper, “A Taphonomic Reassessment of Qafzeh 25 and Its Implications for Violence, Health and Funerary Practices,” appeared in Scientific Reports on June 30, 2026.

As an explosive diarrhea outbreak splatters across the country, Taco Bell is preparing for the worst.
This week, the fast food chain — or at least its locations in Michigan — began temporarily pulling some of its staple ingredients to help stop the spread of cyclosporiasis, a foodborne parasite that causes sufferers to go running to the toilet even more often than a standard Taco Bell meal might.
Many of your favorite menu items, like the Crunchwrap Supreme and the Cantina Chicken bowl, may be imperiled.
“We are currently unable to sell Lettuce, Cilantro Onion, Pico de Gallo, and Guacamole due to a nationwide recall,” a notice posted at locations in Metro Detroit reads, Michigan outlet WWJ reported. “Any items ordered that normally come with these items WILL NOT contain them,” it stressed.
It doesn’t sound like any cases of cyclosporiasis-related explosive diarrhea have been linked to Taco Bell yet, so the fast food chain is probably just trying to err on the side of caution.
So far, nearly 3,000 people have been infected with the foodborne parasite, with around 86 hospitalized, NBC News reported, citing data from the Centers for Disease Control and Prevention. Michigan appears to be one of the epicenters, accounting for over half the reported cases so far.
Cyclosporiasis symptoms are pretty gnarly, but usually not life threatening. It can cause stomach cramps and a lengthy bout of explosive diarrhea. The intensifier is warranted: one sufferer who spoke to the New York Post was in awe of the “amount of pressure when it comes out,” adding that the “force is crazy.”
No food items have been recalled yet related to the outbreak. The virus is usually found on fresh produce, but we don’t know what specific food items are spreading it or the supplier they come from. Cyclosporiasis is notoriously hard to track because the symptoms usually don’t present until at least a week after the contaminated food is ingested.
They may not all come from the same source, the CDC cautioned, and what we’re seeing could be a cluster of unrelated outbreaks.
To protect yourself, the best thing to do is thoroughly wash and cook your veggies, which you should still eat. And maybe skip on the fast food.

Chromosome instability and aneuploidy have long posed a conundrum in cancer biology, profoundly shaping tumor genomes yet remaining challenging to decode functionally. In a groundbreaking study published in Nature, Al-Zahrani et al. unveil a novel approach, CRISPR-KOALA, that systematically links large-scale chromosomal alterations to specific cancer-driving genes in basal-like breast cancer (BLBC).
BLBC, a highly aggressive subtype characterized by extensive copy-number alterations (CNAs), often harbors arm-level chromosomal imbalances whose contribution to tumorigenesis remains elusive. The researchers developed CRISPR-KOALA to conduct high-throughput bidirectional genetic screens directly in immunocompetent mouse models, overcoming previous barriers related to the complexity and scale of genes affected by aneuploidy.
By focusing on the ten most frequent human chromosome-arm alterations seen in BLBC, the team screened over 3,700 mouse orthologues of genes located on these arms. The screen identified 90 putative cancer driver genes—a majority of which had not been previously linked to cancer—revealing a diverse functional landscape shaping tumor biology. Among the implicated pathways were key signaling networks such as MAPK, HIPPO, and WNT, highlighting the heterogeneity intrinsic to BLBC progression.
Strikingly, manipulating these driver genes in Trp53-mutant mouse models was sufficient to bypass the need for whole-arm CNAs, suggesting that tumors exploit specific genes within broad chromosomal alterations to fuel oncogenesis. This finding challenges the traditional view that arm-level aneuploidies function merely as genomic chaos, instead presenting them as evolutionary selections for particular drivers.
One gene, PLGRKT, localized on chromosome 9p, emerged as a potent oncogene. The team showed that PLGRKT promotes tumor growth by enhancing mitochondrial robustness and boosting reactive oxygen species detoxification. This mechanistic insight connects chromosomal instability not only to genetic selection but also to metabolic adaptations that support cancer cell survival under stress.
Overall, this study delivers a transformative platform and a compendium of cancer drivers that illuminate how aneuploidy sculpts tumor heterogeneity. By delineating driver genes nested within widespread CNAs, it provides an invaluable resource for targeting breast cancer’s genetic complexity with greater precision.
The implications extend beyond breast cancer, offering a blueprint for dissecting arm-level aneuploidy in diverse malignancies. As cancer therapies increasingly focus on genetic vulnerabilities, CRISPR-KOALA represents a leap toward untangling the intricate link between chromosome-level alterations and oncogenic processes.
This work underscores the power of integrating genomic data with functional genetics in vivo, setting the stage for novel drug targets and therapeutic strategies aimed at the underexplored realm of aneuploidy-driven tumorigenesis.

During future space missions, humans may finally encounter extraterrestrial life forms, settling the age-old question of whether we are alone in the cosmos. But what if alien biology is so different from that of Earthlings that its presence could become a potential global hazard?
This is the concern raised by researchers Frederick I. Moxley and Anthony Ricciardi in a new study, which argues that in an era of sample return missions and space missions that are carrying humans and our robotic probes farther into the cosmos than ever before, we need to be prepared to enact measures to protect our planet against the unforeseen consequences of any potential alien encounters the future may hold.
“The advancement of space exploration into an era of sample return missions from Mars, asteroids, and icy moons raises the potential for biological contamination either to or from Earth,” the authors write in their recent study, published in the journal Ambio. Given the potential for such contamination, Moxley and Ricciardi approach the question of alien contact from the perspective of past examples where invasive species on Earth have caused major disturbances to the environments they encounter.
“We consider the possibility that extraterrestrial organisms introduced to Earth could behave analogously to invasive species by destabilizing ecosystems or interacting unpredictably with their new environment,” the authors write, pointing to the multitude of examples known to science, many of which involve the introduction of microbial organisms into new environments—often with devastating consequences.
In many cases, such organisms not only can survive in new environments, but can often adapt with remarkable speed, even in some of the most extreme environments.
This, the authors say, challenges the idea that extraterrestrial life might not even be capable of surviving on Earth, as expressed by some past research.
“The plausibility of encountering extraterrestrial life warrants stringent planetary protection measures grounded in biosafety and biosecurity principles,” the authors warn.
So how do they suggest protecting Earth against such potentially catastrophic events involving future encounters with extraterrestrials?
According to Moxley and Ricciardi, building a quarantine facility on the Moon could serve as Earth’s last line of defense against any unintended alien invasions that could radically disrupt Earth’s fragile ecosystems.
“Due to its proximity, natural isolation, and apparent lack of a biosphere, the Moon can serve as a secure site for biocontainment of extraterrestrial samples,” the authors write. In their study, they examine historical instances where biological invasions have led to catastrophic environmental changes and argue that constructing a biocontainment facility on the Moon “should form the cornerstone of modern astrobiological risk mitigation strategies.”
What the researchers propose falls in line with current plans NASA has for a permanent lunar base, which is one of the many ambitious efforts under its Artemis Mission. Such a lunar outpost, which will serve as the official Artemis Base Camp, is planned for construction near the Moon’s South Pole.
At a cost of close to $30 billion, the effort will help to facilitate an ongoing human presence on the Moon by as soon as 2028, according to current mission timelines, and will serve as a science hub in support of future lunar exploration.
For Moxley and Ricciardi, incorporating a quarantine facility within our future lunar infrastructure that can house any extraterrestrial life forms we may encounter could prove to be vital. Ultimately, having such a facility may play the important role of shielding Earth against unintentional contamination by a potentially invasive alien species.
The team’s recent paper, “Protecting earth from extraterrestrial contamination: The case for a lunar biocontainment facility,” was published in Ambio.
