Which statement about lettuce and E. coli O157 is true?

Explanation:
Lettuce can harbor E. coli O157:H7. Leafy greens have been linked to outbreaks where the pathogen contaminated the produce, often via contaminated water, soil, manure, or cross-contamination during handling. E. coli O157:H7 can adhere to or even be internalized in lettuce tissues, and because the infectious dose can be small, contamination can lead to illness despite gaps in washing or detection. Therefore, the statement that lettuce has been known to harbor E. coli O157 is true. The other options imply immunity or impossibility, which isn’t supported by real-world outbreaks and the nature of how produce can become contaminated.
