Japanese Kikubari About an allergy

  I write about Japaense Kikubari after a long time.
In Japan, the bride and groom send a card with an invitation card.
On that card, they ask guest's allergy because the bride and
groom serve guests.
  I got an answer that says he has an allergy of a raw shrimp.
You may not eat an raw shrimp in your culture. So this allergy
sounds special to Japanese culture.
  The cook will prepare the meal without a raw shrimp for him
at the wedding.
  This is Japanese Kikubari.
