What is the most likely allergen that could cause an anaphylactic reaction during a celebration?

While wine does have the potential to cause allergic reactions in some individuals, it is not the most common allergen associated with anaphylaxis during celebrations. It is essential to recognize that both nuts and shellfish are among the leading allergens that frequently lead to severe anaphylactic reactions.

Nuts, particularly peanuts and tree nuts, are notorious for causing life-threatening allergic responses, often in social settings where foods may be shared. Similarly, shellfish allergies are also prevalent and can trigger significant allergic reactions.

Latex can cause anaphylaxis as well, especially in people who are highly sensitive to it, but its occurrence is less common in celebratory environments compared to food-related allergens.

Considering the context of typical celebrations, nuts and shellfish are the allergens most likely to be present in the foods consumed, making them the more probable causes of anaphylaxis.
