Anaphylactic reaction after ingestion of local bee pollen.
A patient is presented who experienced an anaphylactic reaction after ingesting locally produced bee pollen to treat his spring hay fever. Evaluation revealed the patient to be extremely sensitive to mesquite pollen, a major component of the bee pollen he ingested. Passive transfer skin testing and neutralization techniques suggested that the mesquite pollen was the allergen which caused his anaphylactic reaction. Four other allergic patients were known to have systemic reactions after taking bee pollen. The patients received no warning that the bee pollen was potentially dangerous to an allergic person. It is recommended that vendors of bee pollen be required to alert allergic patients about possible risks.
