hives all over body, eyes got all puffy, lost voice and had trouble breathing. We were on a food tour and I hate a dried grasshopper, which is of course a pretty common food in many places of the world. Evidently it won't be for me going forward. I've never had a reaction to any food or any medication until this. Got a bit scary when throat started getting constricted. Thankfully in Mexico City there are pharmacies all over so we got some diphenhydramine and the symptoms largely disappeared within an hour, took about 12 hours for hives to go away.

Evidently this is not uncommon, specifically in Oaxaca, Mexico area, or that style of cooking: "Grasshoppers are highly allergenic insects, which have been associated with allergic rhino-conjunctivitis, contact urticaria, and bronchial asthma after inhalation, contact, or high-level exposure in laboratory workers, hobbyists, from natural exposure, or from ingestion [1]. Although allergy from inhalation of grasshoppers is limited, the ingestion of grasshoppers is extremely common. Eighty percent of the countries in the world ingest over 1700 different insects, of which the most common are grasshoppers and cricket [2]. In Mexico, grasshoppers called chapulines from Oaxaca have been eaten since pre-Columbian times and today are served in restaurants and open markets throughout the country."
