RESUMEN
Anaphylaxis and urticaria are commonly seen in both primary care and allergy clinics. Foods, drugs, and insects are frequent culprits for immediate reactions; however, the trigger for recurring and/or chronic episodes is often unclear. We present a 56-year-old male with recurrent symptoms of urticaria, angioedema, and anaphylaxis found to be triggered by sensitization to galactose-alpha 1, 3-galactose (alpha-gal), a novel food allergen.

On October 27, 2011, the Arkansas Department of Health (ADH) was notified by a northeast Arkansas primary care provider of a cluster of three histoplasmosis cases. On November 4, ADH was notified by a pediatric infectious diseases specialist regarding seven potential cases of pulmonary histoplasmosis associated with a family gathering that included a bonfire that burned bamboo from a grove that had been a red-winged blackbird roost. These reports prompted an outbreak investigation to ensure that the persons involved received appropriate medical care, to identify whether any novel exposures were associated with illness, and to determine whether any factors were associated with hospitalization. The investigation found that, among the 19 attendees at the family gathering, seven were confirmed with histoplasmosis, 11 were probable, and one did not have histoplasmosis.
