Escherichia coli (certain strains)

Escherichia coli, commonly known as E. coli, is a type of bacteria that naturally lives in the intestines of humans and animals, where it helps with digestion. While most strains are harmless, some can cause illness if they contaminate food or water. These pathogenic strains may lead to symptoms like stomach cramps, diarrhea, and sometimes more severe infections. E. coli is often transmitted through undercooked meats, contaminated produce, or unclean water. Proper food handling, cooking, and hygiene are essential to prevent infection. In general, E. coli plays a vital role in our gut health, but certain strains can pose health risks.
