lating multiple lettuce plants with the pathogen, the researchers put them in a growth chamber for a day. They then cut the romaine and placed it in a cooler to simulate harvest and cold storage. Each day over a five-day period, the researchers pulled samples and assayed them for the pathogen. Of particular interest was its state of dormancy.
When under stress, some microorganisms such as E. coli O157:H7 transition to a dormant state known as persister cells. With a slowed metabolism, persist
