Here’s an FDA report on a Romain lettuce E. coli outbreak that resulted in 5 deaths. There’s a couple of ways E. coli can get from cow intestines to lettuce: cow manure gets into irrigation canals/streams, and a downstream farm uses that to water their crops; manure used for fertilizer is not properly treated; cows get into farm fields that they shouldn’t be in. Lettuce is particularly susceptible because it is often eaten raw.
Do tell how that works. Are you imagining herds of cows roaming among the lettuce rows?
