It is very important that balloons are safe and do not cause any harm. Unfortunately, latex balloons can cause reactions to people who are allergic to latex with symptoms ranging from mild irritation of the skin to anaphylaxis. For this reason, I do not recommend any form of latex balloons to be used or to be in the same environment as a person who may suffer from latex allergy. There are other balloon options available including foil and deco balloons so everyone can still enjoy the happiness that balloons bring.
