Listeria Cantaloupe Outbreak Officially Over

The CDC reports that the Cantaloupe outbreak arising from tainted fruit on Jensen Farms is officially over. The CDC said “Available evidence indicates that this outbreak is over. ” The outbreak caused:

  • A total of 146 persons infected with any of the four outbreak-associated strains of Listeria monocytogenes were reported to CDC from 28 states.
  • Thirty deaths were reported. In addition, one woman pregnant at the time of illness had a miscarriage.
Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. Investigators used DNA analysis of Listeria bacteria isolated from patients to identify cases of illness that may have been part of the outbreak. The Listeria bacteria were obtained from diagnostic testing; pulsed-field gel electrophoresis (PFGE) was used to determine DNA fingerprint patterns. Investigators used data from PulseNet, the national subtyping network made up of state and local public health laboratories and federal food regulatory laboratories that performs molecular surveillance of foodborne infections.
