E. coli: a common, but potentially carcinogenic bacterium
Researchers at the University of California analyzed the DNA of nearly 1,000 colorectal tumors and discovered traces of a toxin called colibactin , produced by certain strains of a well-known bacterium: E. coli .
This bacteria, which is found in undercooked ground beef , poorly washed raw vegetables , or even in raw milk , can cause simple digestive problems… but in some people, it could sow the seeds of cancer.
How? By leaving a genetic imprint from childhood, a sort of signature that, years later, promotes the formation of tumors. We are talking here about early mutations, sometimes occurring before the age of 10 .
Where is it hiding? Contamination is more common than we think
Researchers point out that E. coli can be easily transmitted through contaminated irrigation water, contact with livestock, poor kitchen hygiene, etc. Germs such as alfalfa sprouts or young spinach shoots are ideal breeding grounds for its proliferation.
So the danger is everywhere, especially in raw foods . And children, still developing, are the most vulnerable.
