ELI5:Why is romaine lettuce so prone to E.coli?

Thos is atleast the second time this year that and e.coli contamination of romaine lettuce has been in the news? What is it about romaine lettuce that makes it prone to e.coli?

E.coli O157:H7 comes from one place: cow intestines. Cows are not susceptible to the toxin the bacteria produces. Humans, etc. are. So lettuce has it because cow shit was used to fertilize the plant, or a human who got it from eating contaminated cow meat shit on the plant, etc.

Also, never ever eat ground beef unless it is thoroughly cooked. Always wash your hands very well after handling anything which cow shit or cow intestines might have touched, which is basically any kind of meat or vegetable.

If you give your kids raw milk you should just shoot yourself in the face right now.
