Cryptosporidiosis associated with ozonated apple cider.

We linked an outbreak of cryptosporidiosis to ozonated apple cider by using molecular and epidemiologic methods. Because ozonation was insufficient in preventing this outbreak, its use in rendering apple cider safe for drinking is questioned.

Raw eggs--lessons learned from an outbreak of Salmonella serotype enteritidis infections associated with meringue pie.

Objectives: We investigated a salmonellosis outbreak related to a cafeteria to determine its extent and to identify illness risk factors.

Methods: A case was defined as isolation of Salmonella Group D or serotype Enteritidis from the stool of a person who ate at the cafeteria during June 22-July 10, 2003, and developed diarrhea in 3 days or less. Food histories of case patients (n = 11) were compared with those of their well meal companions (n = 16).

Epidemiologic and environmental investigation of a recreational water outbreak caused by two genotypes of Cryptosporidium parvum in Ohio in 2000.

In August 2000, the Ohio Department of Health requested assistance to investigate a cryptosporidiosis outbreak with more than 700 clinical case-patients. An epidemiologic and environmental investigation was conducted. Stool specimens, pool water, and sand filter samples were analyzed.

Legionnaires' disease outbreak in an automobile engine manufacturing plant.

We investigated 4 cases of legionnaires' disease (LD) reported among workers at an Ohio automotive plant in March 2001. A "confirmed" case of LD was defined as x-ray-confirmed pneumonia and a confirmatory laboratory test. A "possible" case of LD was defined as elevated titers of antibody and respiratory symptoms.
