Testing for Anthrax contained in hair within old lime mortars

In historic buildings, animal hair was added to older lime plasters, and renders were frequently reinforced with animal hair (such as from horses, cows, goats, or oxen). There is concern that hair imported or processed before the early 20th century may have carried Bacillus anthracis (anthrax) spores, which can remain dormant in lath and plaster structures for decades.
Renovation or demolition work that generates dust from old, hair-laden plaster can theoretically present exposure risks via skin abrasions or inhalation.

We are registered to handle and request testing at the only lab in the country that undertakes testing for anthrax in hair. Please double bag any samples in strong sealable plastic bags and post to our office address at M. Womersleys, Office 2.18 Holmfield Mills, Holdsworth Road, Halifax, HX3 6SN
