CDC Investigating Outbreak of Severe Salmonella

The Centers for Disease Control and Prevention are currently investigating a multi-state outbreak of Salmonella Dublin infection that has been linked to ground beef.

The outbreak currently involves 10 cases of infection in 6 states, with 3 cases in Colorado, 2 cases in both California and Kansas, and one case in Iowa, Oklahoma, and Texas. The ages of those infected ranged from 48 to 74 years.

Salmonella was found in samples of blood of 5 patients. Illness in this outbreak has been shown to be more severe than in average outbreaks, with 8 of the 10 cases involving hospitalization, including 1 death. The average hospitalization rate for similar outbreaks is 20%. Whole genome sequencing has not revealed any antibiotic resistance in any of the 10 patients or in 6 food specimens.

At this time, a point of origin for the outbreak has not been identified, and the CDC is currently not warning consumers to stop eating thoroughly cooked ground beef.
