Agent CategoryBiological enzyme
Specific AgentBacillus subtilis derived detergent enzymes (protease, amylase, cellulase)
Occupation Detergent industry workers
Outcome/DiagnosisOccupational asthma
Activity Intervention Encapsulation of enzyme, modern process techniques
Participation Rate350 of 432 eligible subjects (Participation rate: 81%)
Intervention EffectivenessEstimated total of 56 cases of occupational asthma in the current workforce is considered as high, or higher, than within the industry before encapsulation.
