It's harder still to get information on how deadly different allergies might be. We track fatalities worldwide using ICD codes, which is an international standardized system for identifying diagnoses and causes of death (it stands for the International Classification of Diseases, and we're on version 10). There are ICD-10 codes for anaphylaxis resulting from unspecific food, peanuts, shellfish, other fish, fruits and vegetables, tree nuts and seeds, food additives, milk and dairy products, eggs, and other food products (T78.00-T78.09). There are also many more codes for medication reactions and deaths due to venom. Unfortunately, none of these are allowed as primary causes of death, so you have to dig deeper into the data and look at secondary codes. One group actually did this for the data from 1999 to 2010, and though they didn't break it down much by specific type of allergy, deaths from food-induced anaphylaxis were the least common type of anaphylaxis death.
