SUNDAY, Nov. 23 (HealthDay News) -- When hosting for the holiday season, be aware that one in six American suffer from either allergies or asthma.

The American Academy of Allergy, Asthma & Immunology offers these tips for party throwers to help ensure their guests' asthma and allergy symptoms don't rear up:

• Ask guests about food allergies before planning your menu. Even trace amounts of an offending food can trigger a reaction. Know what is in each dish and avoid cross-contamination by thoroughly washing utensils, cookware and food storage containers between uses.
• Minimize dust mites, animal dander and other allergens by dusting and vacuuming regularly in the weeks before the event. Vacuum upholstered furniture and drapery as well as carpets.
• Clean or replace furnace air filters so they trap allergens better.
• If people are staying overnight, clean their rooms thoroughly the day they arrive, including washing sheets and pillowcases in hot water.
• Keep pets out of guests' rooms and, if necessary, confined to another area of the house, such as the basement.
• Limit fragrant candles, plants and potpourris. Apply perfume conservatively.
• Don't burn wood in the fireplace as smoke and ash can trigger asthma issues. Require guests who smoke to do so outdoors.
