E. coli strain linked to leafy greens associated with outbreaks, research led by CDC doctor says

A specific strain of E. coli associated with leafy greens has been the source of ongoing enteric illness since late 2016, according to research published in a Centers for Disease Control and Prevention journal. 

The article in the publication Emerging Infectious Diseases – led by Dr. Jessica Chen, who is a bioinformatician in the Division of Foodborne, Waterborne and Environmental Diseases at the CDC’s National Center for Emerging and Zoonotic Infectious Diseases – found that the strain REPEXH02 is estimated to have emerged in late 2015. 

The study’s authors said the agency has classified the strain of E. coli O157:H7 as a reoccurring, emerging or persistent strain. 

“We typically think of foodborne illness as either part of an outbreak or not,” Chen told The Washington Post. “In 2019 we switched to using whole genome sequencing to look at the DNA of a strain and track the bacteria which cause foodborne illness. With this tool we can see if multiple outbreaks are caused by the same strain, and link related illnesses over months and years. We call strains that recur, are emerging or persisting over time REP strains of bacteria.”

Following analysis, an additional outbreak associated with the strain was detected in late 2020, during which 20 people were hospitalized and four developed hemolytic uremic syndrome. Hemolytic uremic syndrome, which is rare but serious, can impede blood clotting in infected people and cause kidney failure.

However, since then, no further outbreaks have been detected.

The article said E. coli O157:H7 is estimated to cause approximately 63,000 domestically acquired foodborne illnesses and 20 deaths across the U.S. annually. 

Such infections are often associated with abdominal cramps, bloody diarrhea and vomiting, in addition to hemolytic uremic syndrome.

While healthy cattle have served as the main vector for the strain, contaminated food, water and environmental sources have also been the source of outbreaks, the authors noted.

“More recently, contaminated leafy greens have been recognized as a major source of E. coli O157:H7 illnesses and outbreaks. In foodborne illness attribution estimates for 2020 based on outbreak data, 58.1% of E. coli O157:H7 illnesses were attributed to vegetable row crops, a category that includes leafy greens. During 2009–2018, a total of 32 confirmed or suspected outbreaks of E. coli O157:H7 infections linked to contaminated leafy greens occurred in the United States and Canada,” the article noted.

It also highlighted that a large E. coli outbreak in late 2019 had caused 167 cases and 85 hospitalizations associated with the consumption of romaine lettuce from Salinas Valley, California.

They concluded that detailed genomic characterization of additional reoccurring, emerging or persistent strains is necessary to explain the factors that contribute to their emergence and persistence in specific environments.

E. coli, also known as Escherichia coli, are a large and diverse group of bacteria found in the environment, foods and intestines of people and animals.

Although most strains are harmless, the CDC notes that others can make you sick.

Kennedy’s Plan for the Drug Crisis: A Network of ‘Healing Farms’

Kennedy’s Plan for the Drug Crisis: A Network of ‘Healing Farms’

Though Mr. Kennedy’s embrace of recovery farms may be novel, the concept stretches back almost a century. In 1935, the government opened the United States Narcotic Farm in Lexington, Ky., to research and treat addiction. Over the years, residents included Chet Baker and William S. Burroughs (who portrayed the institution in his novel, “Junkie: Confessions of an Unredeemed Drug Addict”). The program had high relapse rates and was tainted by drug experiments on human subjects. By 1975, as local treatment centers began to proliferate around the country, the program closed.

In America, therapeutic communities for addiction treatment became popular in the 1960s and ’70s. Some, like Synanon, became notorious for cultlike, abusive environments. There are now perhaps 3,000 worldwide, researchers estimate, including one that Mr. Kennedy has also praised — San Patrignano, an Italian program whose centerpiece is a highly regarded bakery, staffed by residents.

“If we do go down the road of large government-funded therapeutic communities, I’d want to see some oversight to ensure they live up to modern standards,” said Dr. Sabet, who is now president of the Foundation for Drug Policy Solutions. “We should get rid of the false dichotomy, too, between these approaches and medications, since we know they can work together for some people.”

Should Mr. Kennedy be confirmed, his authority to establish healing farms would be uncertain. Building federal treatment farms in “depressed rural areas,” as he said in his documentary, presumably on public land, would hit political and legal roadblocks. Fully legalizing and taxing cannabis to pay for the farms would require congressional action.

In the concluding moments of the documentary, Mr. Kennedy invoked Carl Jung, the Swiss psychiatrist whose views on spirituality influenced Alcoholics Anonymous. Dr. Jung, he said, felt that “people who believed in God got better faster and that their recovery was more durable and enduring than people who didn’t.”

The debate about the benefits and risks of fluoride is ongoing, as RFK Jr. — incoming President Trump’s pick for HHS secretary — pushes to remove it from the U.S. water supply.

“Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders and thyroid disease,” RFK wrote in a post on X in November.

A new study published in JAMA Pediatrics on Jan. 6 found another correlation between fluoride exposure and children’s IQs.

RFK JR. CALLS FOR REMOVAL OF FLUORIDE FROM DRINKING WATER, SPARKING DEBATE

Study co-author Kyla Taylor, PhD, who is based in North Carolina, noted that fluoridated water has been used “for decades” to reduce dental cavities and improve oral health.

“However, there is concern that pregnant women and children are getting fluoride from many sources, including drinking water, water-added foods and beverages, teas, toothpaste, floss and mouthwash, and that their total fluoride exposure is too high and may affect fetal, infant and child neurodevelopment,” she told Fox News Digital.

The new research, led by scientists at the National Institute of Environmental Health Sciences (NIEHS), analyzed 74 epidemiological studies on children’s IQ and fluoride exposure.

The studies measured fluoride in drinking water and urine across 10 countries, including Canada, China, Denmark, India, Iran, Mexico, Pakistan, New Zealand, Spain and Taiwan. (None were conducted in the U.S.)

The meta-analysis found a “statistically significant association” between higher fluoride exposure and lower children’s IQ scores, according to Taylor.

“[It showed] that the more fluoride a child is exposed to, the more likely that child’s IQ will be lower than if they were not exposed,” she said.

These results were consistent with six previous meta-analyses, all of which reported the same “statistically significant inverse associations” between fluoride exposure and children’s IQs, Taylor emphasized.

The research found that for every 1mg/L increase in urinary fluoride, there was a 1.63-point decrease in IQ. 

‘Safe’ exposure levels

The World Health Organization (WHO) has established 1.5mg/L as the “upper safe limit” of fluoride in drinking water.

“There is concern that pregnant women and children are getting fluoride from many sources.”

Meanwhile, the U.S. Public Health Service recommends a fluoride concentration of 0.7 mg/L in drinking water.

“There was not enough data to determine if 0.7 mg/L of fluoride exposure in drinking water affected children’s IQs,” Taylor noted.

FDA BANS RED FOOD DYE DUE TO POTENTIAL CANCER RISK

Higher levels of the chemical can be found in wells and community water serving nearly three million people in the U.S., the researcher noted.

She encouraged pregnant women and parents of small children to be mindful of their total fluoride intake.

“If their water is fluoridated, they may wish to replace tap water with low-fluoride bottled water, like purified water, and limit exposure from other sources, such as dental products or black tea,” she said.

“Parents can use low-fluoride bottled water to mix with powdered infant formula and limit use of fluoridated toothpaste by young children.”

While the research did not intend to address broader public health implications of water fluoridation in the U.S., Taylor suggested that the findings could help inform future research into the impact of fluoride on children’s health.

Dental health expert shares cautions

In response to this study and other previous research, Dr. Ellie Phillips, DDS, an oral health educator based in Austin, Texas, told Fox News Digital that she does not support water fluoridation.

“I join those who vehemently oppose public water fluoridation, and I question why our water supplies are still fluoridated in the 21st century,” she wrote in an email.

“There are non-fluoridated cities and countries where the public enjoy high levels of oral health, which in some cases appear better than those that are fluoridated.”

Phillips called the fluoride debate “confusing” even among dentists, as the American Dental Association (ADA) advocates for fluoride use for cavity prevention through water fluoridation, toothpaste and mouthwash — “sometimes in high concentrations.”

“[But] biologic (holistic) dentists generally encourage their patients to fear fluoride and avoid its use entirely, even if their teeth are ravaged by tooth decay,” she said.

“Topical fluoride is beneficial, while systemic consumption poses risks.”

Phillips encouraged the public to consider varying fluoride compounds, the effect of different concentrations and the “extreme difference” between applying fluoride topically and ingesting it.

“Topical fluoride is beneficial, while systemic consumption poses risks,” she cautioned. 

“Individuals must take charge of their own oral health using natural and informed strategies.”

The study received funding from the National Institute of Environmental Health Sciences (NIEHS), the National Institutes of Health (NIH) and the Intramural Research Program.
