Chronic exposure to chili peppers in spice workers is linked to increased cough prevalence. However, it does not solely decrease nerve sensitivity to capsaicin, suggesting other factors modify cough responses.

Area of Science:

  • Occupational Health
  • Respiratory Medicine
  • Toxicology

Background:

  • Workers in spice manufacturing facilities are chronically exposed to hot chili (Capsicum) peppers.
  • The health effects of such occupational exposure, particularly on respiratory symptoms and nerve sensitivity, require investigation.

Purpose of the Study:

  • To assess the impact of chronic Capsicum pepper exposure on respiratory symptoms.
  • To evaluate changes in lung function and cough threshold to capsaicin in exposed workers.

Main Methods:

  • A cross-sectional study compared 22 Capsicum-exposed workers with 19 non-exposed workers from a spice manufacturing facility.
  • Data collected via questionnaires, spirometry for lung function, and capsaicin inhalation challenge for cough threshold.

Main Results:

  • Capsicum-exposed workers reported significantly higher cough prevalence (59% vs 21%).
  • No significant difference in baseline lung function (FEV1, FVC) was observed between groups.
  • Cough threshold to capsaicin showed a bimodal pattern in exposed workers, suggesting altered nerve responsiveness potentially influenced by gender, diet, and smoking.

Conclusions:

  • Chronic occupational exposure to chili peppers is associated with increased cough complaints.
  • Exposure alone does not appear to decrease capsaicin-sensitive nerve responsiveness, indicating a complex interplay of factors.
  • Further research is needed to understand the interactive effects of various factors on cough response in exposed populations.
