Wendy's Romaine E. coli Outbreak Grows to 97 in 6 States


Marler Clark is currently representing 33 individuals in this E. coli outbreak, including 4 with Hemolytic Uremic Syndrome (HUS).

Update: As of September 2, 2022, the CDC reports a total of 97 illnesses in the Wendy's E. coli outbreak. Two states- Kentucky and New York (with one case each) - have been added to the list of states reporting cases, which now include Michigan (58), Ohio (24), Indiana (11) and Pennsylvania (2).

These numbers may not accurately reflect the number of people affected; the Health Department sites for Ohio, Michigan, Indiana and Pennsylvania report the number of people infected as higher than 150.

Where Sick People Lived

There are consistent reports of when the illnesses started, the dates range from July 26, 2022, to August 15, 2022.

When People Got Sick


Sick people range in age from 3 to 94 years, with a median age of 22 years, and 55% are male. Of 81 people with information available, 43 have been hospitalized. Ten people in Michigan have developed a type of kidney failure called hemolytic uremic syndrome. No deaths have been reported at this time.

The true number of sick people in this outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some of the recent illnesses have not yet been reported to PulseNet, as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak. In addition, some people recover without medical care and are not tested for E. coli.

State and local public health officials have been interviewing people about the foods they ate in the week before they got sick. Among 67 people who have been interviewed, 54 (81%) reported eating at a Wendy’s restaurant in the week before their illness started.

The Wendy’s restaurants where sick people ate are in Indiana, Michigan, Ohio, and Pennsylvania. People reported eating a variety of menu items, including burgers and sandwiches. Of 54 people with detailed information about what they ate at Wendy’s, 37 (69%) reported eating romaine lettuce served on burgers and sandwiches. Investigators continue to analyze data at the ingredient level to determine if there are any other possible foods that could be the source of the outbreak.

National Center for Biotechnology Information (NCBI) update 8/29

Note, the SNP Cluster # is dynamic and changes as more isolates are added

SNP Cluster PDS000116884.1

94 Isolates Selected

Distance between selected isolates: minimum = 0 SNPs, maximum = 3 SNPs, average = 0 SNPs

73 are 0 Single Nucleotide Polymorphisms (SNPs). This means that there are no genetic variations in the genotype "fingerprint"; they all match and most likely came from the same food that made everyone sick.
