Anthrax continues to pose a threat to workers handling certain raw animal fibres. The disease is endemic in many countries, including some of those from which goat hair and wool are imported. Dust from anthrax contaminated fibres can cause potentially fatal pulmonary or skin forms of the disease. However, while anthrax is still being detected in imported fibres, the incidence of the human disease in the UK has fallen sharply; for reasons that are not entirely clear.
