Allergies can be seasonal (worsening during certain times of the year, such as pollen allergies in the spring) or perennial (occurring year-round). Common allergens include weed or grass pollen, dust mites, animal dander, mold, insect stings and a variety of food types, such as eggs, shellfish, nuts and grains. Insect Sting Allergy. Stings from five insects - honeybees, hornets, wasps, yellow jackets and fire ants - are known to cause allergic reactions to the venom injected into the skin. Pet allergies can contribute to constant allergy symptoms, such as causing your eyes to water, or causing you to start sneezing.

The proteins in the fruits and vegetables that cause OAS are easily broken down with cooking or processing; therefore symptoms don’t usually occur with cooked or processed foods like tomato sauce.
