Procedures for Collecting and Processing Environmental Specimens for Legionella spp.
- Collect water (1-liter samples, if possible) in sterile, screw-top bottles.
- Collect culture swabs of internal surfaces of faucets, aerators, and shower heads in a sterile, screw-top container (e.g., 50 mL plastic centrifuge tube). Submerge each swab in approximately 5 mL of sample water taken from the same device from which the sample was obtained.
- Transport samples and process in a laboratory proficient at culturing water specimens for Legionella spp., as soon as possible after collection.
- Test samples for the presence of Legionella spp. by using semiselective culture media using procedures specific to the cultivation and detection of Legionella spp.
