Occupational egg allergy in an embryological research facility

Area of Science:

• Occupational Health
• Immunology
• Allergy Research

Background:

• Hen and quail eggs are vital in embryological research.
• Egg protein allergy (immunoglobulin E-associated) is known in the food industry.
• No prior reports existed for embryology research workers.

Observation:

• Two cases of egg sensitization identified in research workers.
• A survey of 116 laboratory employees was conducted.
• Sensitization assessed via skin prick tests and IgE measurement.

Findings:

• Prevalence of egg sensitization was 6.1% among directly exposed workers.
• All sensitized individuals reported digestive symptoms consistent with egg allergy.
• Shorter exposure duration and less frequent hygiene use correlated with sensitization.

Implications:

• Occupational egg sensitization is more common in research than the general population.
• Digestive symptoms post-egg consumption may indicate sensitization.
• Health evaluations for exposed workers should include egg allergy screening.
