Since the previous update on November 26, an additional 35 ill people have been reported. As of December 2, 2019, a total of 102 people infected with the outbreak strain of E. coli O157:H7 have been reported from 23 states. AZ (3), CA (4), CO (6), FL (1), IA (1), ID (3), IL (1), MD (4), MI (1), MN (3), MT (1), NE (1), NJ (7), NC (1), NM (2), OH (12), OR (1), PA (8), SD (1), TX (4), VA (4), WA (2), WI (31).
Illnesses started on dates ranging from September 24, 2019, to November 18, 2019. Ill people range in age from less than 1 to 89 years, with a median age of 25. Sixty-five percent of ill people are female. Of 98 ill people with information available, 58 hospitalizations have been reported, including 10 people who developed hemolytic uremic syndrome (HUS), a type of kidney failure. No deaths have been reported.
Epidemiologic, laboratory, and traceback evidence indicate that romaine lettuce from the Salinas, California, growing region is the likely source of this outbreak.
FDA and states continue to trace the source of the romaine lettuce eaten by ill people. Preliminary information indicates that some of the ill people ate lettuce grown in Salinas, California. No common grower, supplier, distributor, or brand of romaine lettuce has been identified.
CDC continues to advise that consumers not eat and retailers not sell any romaine lettuce grown in Salinas, California. The investigation is ongoing to determine the source of contamination and if additional products are linked to illness.
We need to take a hard look at the safety of romaine and what we can do to make is safe.
At this time, there is no outbreak of E. coli occurring in Canada. There is one Canadian illness related to the U.S. outbreak that has been identified in the province of Manitoba. This individual became ill in mid-October.
