Reports have been received of possible cases of avian botulism in Bristol Harbour.
The Harbour Authority was advised yesterday evening by Bath Swan Rescue of a possible outbreak of avian botulism affecting birds within Bristol Harbour. As things stand, we await confirmation from Department for Environment, Food and Rural Affairs (DEFRA) testing. The issue is being treated as a precautionary incident, with early intervention measures implemented while awaiting laboratory confirmation. Whilst these reported cases are a cause for us to be alert to potentially infected birds, it is not a cause for any alarm.
Precautionary measures currently being undertaken are:
• Harbour teams instructed to undertake enhanced patrols for sick or dead birds
• Arrangements made for litter removal and inspection of areas with high bird activity, including St Augustine's Reach and reed bed areas.
• Public warning notices and posters deployed around affected locations.
• Liaison with the Parks team to share risk assessments and safe systems of work for handling deceased birds. This follows similar reports in St George’s Park, and in other areas in the region such as Bath and Bradford-on-Avon.
The advice for residents, visitors and businesses is as below. This is being shared via posters across the harbour estate, direct with stakeholders and via the press:
• Do not touch sick, injured, or dead animals
• Keep dogs on a lead near the harbour
• Do not allow dogs to enter the water
• Do not feed wild birds
• Avoid contact with the water where possible
• If fishing, do not use organic bait including live bait, bread or meat.
• If you find a dead or sick bird or fish in the Harbour please do one of the following:
o Phone Bristol City Council on 0117 9222 000; or
o Visit our website to Report a dead animal that needs to be removed
Updates will be shared once more information is gathered and further assessments have been undertaken.
