We recently conducted an anthrax survey at a historic building in London. The primary aim was to assess the presence of animal hair in the plaster, which could potentially harbour Bacillus anthracis spores, the bacteria responsible for anthrax. This was crucial to ensure the safety and health of the building's occupants and workers, especially considering the age and construction methods used in historic structures.
Our team carried out a thorough inspection of all accessible areas within the building. This included taking bulk samples of plaster from walls and ceilings to identify any contamination. The samples were then analyzed for the presence of Bacillus anthracis spores.
Fortunately, our findings indicated that no animal hair plaster contaminated with Bacillus anthracis was identified on-site. The sampled materials did not present any immediate risk, but we still recommend regular monitoring and precautionary measures during any future refurbishment or demolition work to prevent any potential exposure.
The survey aimed to assess the extent of historic plaster containing animal hair in a three-storey listed building. The focus was on external walls of the Saloon and Boudoir rooms on the ground floor, which had suffered water ingress, damaging the internal plaster. Our methodology included a comprehensive visual inspection of accessible areas and sampling of suspected animal hair plaster for microbiological analysis. Despite limited access to certain areas, we assumed non-accessible sections might contain historic animal hair plaster. Samples were analysed by the UKAS accredited Rare and Imported Pathogens Laboratory. The results showed no presence of historic plaster with animal hair, and Bacillus Anthracis was not detected in any samples. Therefore, no further actions are required concerning historic plaster in this property. All health and safety measures were strictly followed, ensuring minimal risk to occupants and visitors.
