Asylum seekers are being moved off the Bibby Stockholm after bacteria was found in the water.

It is understood Legionella has been found in the water on the barge at Portland Port, Dorset.

Legionella bacteria can cause a serious type of pneumonia called Legionnaires’ disease.

All 39 asylum seekers are being disembarked from the barge as a precaution.

A Home Office spokesperson said: “The health and welfare of individuals on the vessel is our utmost priority.

“Environmental samples from the water system on the Bibby Stockholm have shown levels of legionella bacteria which require further investigation.

“Following these results, the Home Office has been working closely with UKHSA and following its advice in line with long-established public health processes, and ensuring all protocol from Dorset Council’s Environmental Health team and Dorset NHS is adhered to.

“As a precautionary measure, all 39 asylum seekers who arrived on the vessel this week are being disembarked while further assessments are undertaken.

“No individuals on board have presented with symptoms of Legionnaires’, and asylum seekers are being provided with appropriate advice and support.

“The samples taken relate only to the water system on the vessel itself and therefore carry no direct risk indication for the wider community of Portland nor do they relate to fresh water entering the vessel. Legionnaires’ disease does not spread from person to person.”
