Outbreak of E. coli Infections in 6 States Being Investigated: CDC

Atlanta, GA–CDC, public health and regulatory officials in several states, and the U.S. Food and Drug Administration are investigating several multistate outbreaks of E. coli O157:H7 infections.

Twelve people infected with the outbreak strain of E. coli have been reported from six states. Five people have been hospitalized. No deaths have been reported.

On November 6, 2020, Tanimura & Antle recalled its packaged single-head romaine lettuce after officials in Michigan identified E. coli 0157:H7 in the romaine lettuce during routine sampling.

Whole genome sequencing showed that the sample of romaine was the same as the strain identified among ill people associated with this outbreak. However, this data alone is not enough to prove a link in the outbreak.

The investigation is ongoing to determine if ill people got sick from eating recalled Tanimura & Antle packaged single head romaine lettuce.

CDC will provide updates when more information becomes available.

This outbreak is different from two other E. coli outbreaks that CDC recently communicated about: E. coli outbreak in 8 states and E. coli outbreak in 12 states.

  • People usually get sick from Shiga toxin producing E. coli (STEC) 2-8 days (average of 3-4 days) after swallowing the germ.
  • Symptoms often include severe stomach cramps, diarrhea (often bloody), and vomiting. Some people may have a fever, which usually is not very high (less than 101°F/38.5°C).
