Just when you thought you knew everything about allergies, the American Academy of Allergy, Asthma and Immunology throws another curve at you: dust mites.
These microscopic critters live in bedding and carpeting, but they can also find their way into the dust on top of canned goods.A dust mite allergy might be suspected if you eat ordinary food from a can, like tuna or soup, and soon your eyes start watering and you experience severe sneezing, your throat itches or your face swells.
For this reason, doctors and allergists tell consumers to wash off the tops of all cans before opening them. They also recommend storing grains and flours in the refrigerator or in cool cupboards in airtight containers. Dust mites thrive in warm, moist climates.
If the problem persists, you may want to see an allergist, who can determine whether dust mites or something else is at the root of your problems.
