Escherichia coli 0157:H7

A strain of E. coli that may cause bloody diarrhea (and other more serious illnesses) as a result of its production of a potent toxin. Outbreaks of diarrheal illnesses caused by 0157:H7 have occurred in day care centers, families, farms, fast-food restaurants, nursing homes, petting zoos, and schools. The organism may contaminate undercooked meat, esp. hamburger; unpreserved apple cider; vegetables grown in manure; or contaminated water supplies. The infection caused by this bacillus may spread from animal-to-person, person-to-person, or through contamination of food or water.

Symptoms

Asymptomatic infection is common. In other cases, after the 3- to 8-day incubation period, an afebrile and self-limiting diarrhea occurs; however, the infection may progress to hemorrhagic colitis with bloody diarrhea, severe abdominal pain, and low-grade fever. Resolution usually occurs in 1 week. In about 15% of cases, patients develop hemolytic uremic syndrome (HUS); the mortality among patients who develop HUS ranges from 3 to 5%. The highest incidence of HUS is found among children and older adults.

Diagnosis

Without a high index of suspicion, diagnosis in either a lone case or an outbreak may be delayed. To prevent unnecessary diagnostic or therapeutic intervention, such as colonoscopy or colectomy, diagnosis should be made as quickly as possible.

Prevention

Ground meat should be cooked until it reaches a temperature of 160°F (71.1°C) and the meat should not be pink in the center. Leftovers should be reheated to 165°F (73.3°C). Individuals who change a baby's diapers should thoroughly wash their hands immediately afterward. Food handlers must wash their hands after using the toilet.
