Some people have allergies to foods. A common food allergy is peanuts. This allergy can be very dangerous because a lot of foods are prepared with peanut oil. If you are allergic to peanuts, care should be taken when purchasing food. Read all lables to make sure that foods do not contain peanuts or peanut oil.
Many insects can also cause an allergic reaction to a person with a sensitivity to insect venom.
Some of the most common insects that people are allergic to are hornets, fire ants and fleas. Just one sting or bite from an insect on a person who is severely allergic can cause death. A bee sting kit should always be carried by a person who is allergic. Most people will have a reaction to allergens such as poison ivy and poison oak plants. Once exposed to the juices of these plants an itchy rash will most likely occur.
