Sample text

Most of the water used by the spa and all of the water for the bottling plant came from spring A, which entered a concrete covered underground reservoir excavated in the limestone from which the spring emerged. Untreated water from this reservoir was piped to the baths, a swimming pool, multiple drinking water sources, and the water bottling plant. A small river carrying sewage from upstream towns ran near the springs. 1. At the bottling plant approximately half of the water was carbonated before bottling, and half was bottled without treatment.

Where did the organism come from in this particular outbreak? How was that fact established? What are the characteristics of the organism? Does it survive in sewage, river water, seawater, bottled water, in chlorinated water? When and where does it grow? Does it grow in shellfish? does it grow in any types of waters? Does it grow in foods? What is the infective dose to cause illness? How does it cause illness? What are the symptoms of cholera? How is the cholera organism detected in food and water samples?

Outside the body the organism is killed easily at temperatures above 56 "C; and it dies rapidly when dried, but it survives readily in alkaline waters for many days (ICMSF, 1996). In the waters and foods affected in the Portugal outbreak the organism both survived for periods long enough to infect consumers and, depending on the precise circumstances, may have actually grown. Clearly in many samples the time period between infection and consumption could have been such that the organisms had diminished in numbers or died out completely.
