A shadowy suspect may be lurking in the nation’s favorite poultry—research now points toward a bacterial menace in chicken that could be playing a sinister role in the unsettling rise of aggressive colon cancer, particularly in younger individuals.
Historically, red and processed meats bore the brunt of cancer blame, but the chicken had long enjoyed a safer reputation. That shield may now be cracking. Emerging investigations suggest a strain of the bacteria Campylobacter jejuni—commonly found on raw poultry—might act as an unseen accelerator of colon cancer, potentially by triggering genetic injuries at the cellular level.
Campylobacter remains a leading culprit in foodborne illness, typically provoking transient bouts of diarrhea, queasiness, and stomach unrest. While most recover in a matter of days, the bug can prove lethal for those with fragile immunity—young children, the elderly, and chronically ill individuals, according to reports by DailyMail.
Though causality has not been definitively cemented, scientists warn that exposure to Campylobacter jejuni may heighten susceptibility to colon malignancies. Intriguingly, recent discoveries from Italian researchers echo this concern—those ingesting more than 300 grams of poultry weekly, or roughly four servings, appeared to double their risk of succumbing to eleven distinct cancers, particularly gastrointestinal ones.

Colon cancer, once relegated to the aging populace, is now eerily advancing in individuals in their 20s, 30s, and 40s, leaving clinicians perplexed. In a meticulous U.S. study, researchers monitored over 70 patients grappling with the disease. A sobering pattern emerged: higher levels of Campylobacter jejuni were found in patients whose cancers had metastasized beyond the colon, compared to those whose tumors remained localized.
Reporting in Cell Host & Microbiome, scholars drew attention to the bacterial toxin cytolethal distending toxin (CDT), a known aggressor capable of ravaging DNA. Professor Christian Jobin of the University of Florida explained that CDT appears to be a vital cog in this malignancy machine—when it migrates to tumorous sites beyond the intestines, it seemingly stokes cancer’s expansion.
Parallel lab tests using mice implanted with human colon cancer tissue confirmed the suspicion—CDT seemed to turbocharge the tumors’ spread, as reported by DailyMail.
Despite the gravity of these insights, the experts caution that further trials involving human subjects are vital to draw definitive conclusions.
Meanwhile, surveillance data from the UK reveals a 27% spike in lab-confirmed Campylobacter cases between 2022 and 2024. Regulatory bodies such as the Food Standards Agency (FSA) require supermarkets to disclose quarterly data on poultry contamination levels, particularly when bacteria exceed 1,000 CFU/g—an alarming threshold marking high-risk meat, according to DailyMail.
Aside from the toll on health, Campylobacter exacts a heavy economic burden—estimated to sap the UK economy of nearly £900 million annually, through both healthcare costs and lost productivity.
To mitigate risk, the FSA underscores practical food safety: never rinse raw chicken (to prevent bacteria from splattering), cook it fully, store it chilled, and maintain strict hygiene when handling it.
The Italian cohort study, spanning nearly two decades and tracking close to 5,000 participants, mainly in their 50s, further fuels concern. It posits that cooking chicken at elevated temperatures might produce carcinogenic chemicals, while feed additives, hormones, or antibiotic residues used in poultry farming could also be influencing cancer risk, according to DailyMail.
And it’s not just Campylobacter under scrutiny. The stomach bug Helicobacter pylori has also been implicated in upsetting the gut’s microbial harmony, possibly opening doors to colon cancer. Likewise, other bacterial offenders—Fusobacterium nucleatum and select E. coli variants—have drawn attention for their potential roles in oncogenesis.
In a chilling revelation, researchers last week found traces of colibactin—a toxin associated with certain E. coli strains—in the tumor DNA of colon cancer patients under 40. This large-scale analysis spanned 11 countries and included nearly 1,000 tumor samples.
Adding to this mosaic of concern, public health figures from England show an almost tenfold leap in cases of a rare E. coli strain commonly found in tainted lettuce over the past seven years. Experts attribute the trend to heightened awareness, climate change, and broader consumption of risk-prone foods like bagged salads or pre-made sandwiches, according to reports by DailyMail.
Startlingly, leafy greens are now suspected in over half of all E. coli outbreaks—showing that the threat isn’t just hiding in meat, but also in the very vegetables many turn to for better health.
