There's a small list of commonly deadly allergens, but there's a ton of diversity in the population of people, and some people react with anaphylaxis for items beyond the top 8 or 9.

> Asero and colleagues29 recently reported on a series of 1110 adolescent and adult Italian patients (mean age 31 years, range 12–79 years) diagnosed with food allergy based on history of reaction in the presence of positive skin prick test (SPT) or elevated food-specific serum IgE. Anaphylaxis was reported by 5% of food-allergic individuals, with the most common cause being lipid transfer protein (LTP). LTP is a widely cross-reacting plant pan-allergen. Offending food for LTP-allergic patients was most often peach, but included also other members of the Rosaceae family of fruits (apple, pear, cherry, plum, apricot, medlar, almond, strawberry), tree nuts, corn, rice, beer, tomato, spelt, pineapple, and grape. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440177/#:~:tex...
