Guidance on Microbial Contamination in Previously Flooded Outdoor Areas
Microbial contamination—both bacterial and viral—of flood waters can cause great concern for use of previously flooded outdoor areas. Limited guidance exists on how to determine safe use of these areas. The CDC has developed a document for public health authorities, emergency response managers, and government decision makers. This document defines how to assess the public health risks for using outdoor areas after a flood event where potential exposure to microbial contamination exists.
