Workers formulating lactase products may develop occupational sensitization, leading to allergic reactions like rhinitis and asthma. Atopic individuals appear to be at higher risk, suggesting lactase as a potential respiratory sensitizer.

Area of Science:

  • Occupational Health
  • Allergology
  • Biochemistry

Background:

  • Lactase is an enzyme used in consumer products to aid lactose digestion.
  • Lactose intolerance causes gastrointestinal distress.
  • Occupational exposure to enzymes can lead to sensitization.

Purpose of the Study:

  • To investigate occupational sensitization to lactase in workers.
  • To identify potential health risks associated with lactase formulation and packaging.
  • To evaluate lactase as a respiratory sensitizer in the workplace.

Main Methods:

  • Case reporting of allergic symptoms in workers.
  • Clinical observation of allergic rhinitis, conjunctivitis, and asthma.
  • Assessment of risk factors, including atopy.

Main Results:

  • Occupational sensitization to lactase was observed in workers.
  • Reported symptoms included allergic rhinitis, conjunctivitis, and asthma.
  • Atopic individuals showed a potential for increased sensitization risk.

Conclusions:

  • Lactase should be recognized as a potential occupational respiratory sensitizer.
  • Workplace exposure during lactase product formulation and packaging poses sensitization risks.
  • Further attention to atopic individuals in occupational settings is warranted.
