Deadliest legionella strain found onboard Bibby Stockholm

Exclusive: Data from Dorset council shows Legionella pneumophila Serogroup 1 was discovered on 15 August

New testing of water samples on the Bibby Stockholm has confirmed the presence of a potentially deadly strain of legionella onboard, the Guardian has learned.

The presence of legionella bacteria on the barge, which the Home Office has said can accommodate more than 500 asylum seekers, was initially detected in tests returned on the first day people boarded, on 7 August. It was publicly confirmed by the Home Office on 11 August and officials evacuated all 39 people onboard that day.
