Occupational asthma caused by sensitization to a cleaning product containing triclosan

A recent consensus statement has highlighted the increased risk of developing asthma after exposure to workplace and domestic cleaning products.1 Specific cleaning agents, such as benzylalkonium chloride, have been recognized as causes of occupational asthma by sensitization and now comprise a significant burden of work-related asthma. European Respiratory Society guidelines recommend that sensitizer-induced occupational asthma should be diagnosed by identifying the workplace as the cause and confirming sensitization to an asthmagen by specific inhalation challenge (SIC) in the absence of any available specific IgE tests.
