Friday Favorites: Urinary Tract Infections from Consuming Hen


Beneath is an approximation of this video’s audio content material. To see any graphs, charts, graphics, photos, and quotes to which Dr. Greger could also be referring, watch the above video.

Solely about one in 4 folks have heard of Campylobacter, in comparison with 90% conversant in Salmonella. “Though the incidence of those two…gastrointestinal infections is amazingly excessive,” infecting greater than one million Individuals yearly, “it’s…outranked by the incidence of” a bug even fewer folks have seemingly heard of: ExPEC–extraintestinal [meaning outside of the intestines, like as in causing bladder infections] pathogenic [meaning disease-causing] E. coli leading to thousands and thousands of infections yearly. “[M]ultiple strains of proof indicat[e] poultry [may be] a serious meals animal reservoir for [bacteria that cause] urinary tract infections” in folks, as I explored about 5 years in the past. That is based mostly not solely on research exhibiting these sorts of E. coli from business rooster meat and eggs could cause blood infections, mind infections, and urinary tract infections in mouse fashions, research on girls with multidrug-resistant urinary tract infections do report considerably extra frequent retail rooster consumption. Equally, aged rooster eaters had been considerably extra more likely to have Cipro-resistant bladder infections in comparison with these consuming no rooster in any respect. Pork was additionally related to elevated danger, however not beef.

“There have been few noticed associations between beef cattle or retail beef and human ExPEC [infections], suggesting that beef cattle will not be a reservoir for human” bladder infections, whereas in chickens, of the as much as 90% of rooster carcasses harboring E. coli, about 1 in 5 isolates examined “had the potential to trigger [urinary tract infections].”

What about eggs? We all know retail rooster meat “is contaminated with ExPEC isolates that resemble the strains that trigger human infections,” however what about retail rooster eggs? As a substitute of 1 in 5 being ExPEC in rooster meat, it was extra like only one in 20 amongst eggs—nearer to down round pork or beef ranges.

Researchers are so certain that rooster is the first reservoir that after they discover the identical sort of pressure in a vegetarian, they interpret that as folks saying they’re vegetarian, however really consuming some rooster, or proof of “human-to-human transmission,” and even shopping-cart-to-human transmission. Bear in mind how most individuals fail to sanitize their arms after selecting up a bundle of poultry within the grocery retailer? And so then, even “[a] shopper who’s not buying poultry might nonetheless be uncovered” to poultry contamination, pushing the identical cart after them. 

“It’s troublesome to estimate how a lot ExPEC alternate will be attributed to person-to-person contact” after a rooster shopper’s rectum has been colonized. Researchers went swabbing round public restrooms to attempt to quantify the danger—a thousand samples from 56 public restrooms in 33 institutions. They discovered plenty of proof of E. coli normally, significantly in public park restrooms and quick meals joints—greater than fuel stations, which shocked me. However this was actually stunning—girls’s rooms had been worse than males’s!

However solely about 1% of the samples they took had been optimistic for ExPEC micro organism, although they had been recovered from non-toilet related websites, that had been not visibly contaminated. So, one may contact it with naked arms after like turning the tap off after you’ve washed your arms, so the danger will not be absolutely eradicated by cautious handwashing “or avoidance of fecal-appearing particles,” although that’s in all probability a good suggestion to keep away from anyway. And, “utilizing hand sanitizers after exiting the restroom,” to not point out within the meat aisle “after touching” a bundle of poultry, might provide further safety.

What quantity of the seven million bladder infections yearly within the U.S. are as a consequence of rooster meat? Like, “if no extra rooster had been consumed, what number of E. coli UTIs could be prevented?” “[H]ow a lot would the prevalence decline?” It’s onerous to inform due to “the time lag between the acquisition and asymptomatic colonization of the gut with an ExPEC organism and the event of an an infection.” So, you eat some contaminated rooster at this time, and the UTI-causing ExPEC micro organism might hand around in your colon for months earlier than making its approach into your bladder and triggering an an infection. The rationale we all know it may take that lengthy is by learning the intestinal inhabitants dynamics of UTI-causing E. coli between companions. “Elevated rectal-rectal transfers… may be defined by the excessive ranges of E. coli current within the urine of an contaminated lady,” which might then be transferred over relying on….sure intimate practices.

Backside-line, there’s “compelling proof that retail meat, significantly poultry, serves as an vital reservoir for human publicity to antibiotic-resistant E. coli that’s inflicting UTIs”—urinary tract infections. Thus, as an alternative of simply UTIs, possibly we should always name them foodborne UTIs or “FUTIs”—or possibly pronounced F.U.TIs.

Positive, we might lower the burden of those foodborne bladder infections by growing some form of ExPEC vaccine, or we might simply lower down our contact with contemporary or frozen poultry. No hurt; no fowl.

Please think about volunteering to assist out on the positioning.
