Of course, so?
When you farm livestock commercially, you do so in tightly group environments, and have to use antibiotics to keep the animals healthy. The e.coli in said animals' colons can develop defences against said antiB's - so the farmers switch. Once food matter passes through the digestive tract, it becomes infected with e/coli that has AB suppressive properties. Commercial farms sell off their poop to regular farmers. e.coli can survive for months outside of the body.
So..you have resistant e.coli being shipped and used on farmers fields. The e.coli can and does survive on the seeds planted and the seedlings, and the veg.
