Food Microbiology - Targeted Survey - Final Report - Bacterial Pathogens and Indicators in Imported Romaine Lettuce - April 1, 2019 to March 31, 2024

A 5-year targeted survey analyzed 4,450 samples of a variety of imported romaine lettuce product types, including whole and fresh-cut salads, for the presence of E. coli O157, Salmonella, and generic E. coli. E. coli O157 and Salmonella were not found in any of the samples. Generic E. coli at elevated levels was found in one sample but no further actions were required. Unlike bacterial pathogens, most strains of generic E. coli are harmless.
