Accompanying Information
Cross contact is the presence of unintended food allergen. Exposure to an allergen by cross contact is a common cause of allergic reactions. Cross contact of food allergen can occur from contact with surfaces, other foods, and with transfer of saliva. If a person is then exposed to these allergens, especially by mouth, it may be enough of an exposure to cause a serious allergic reaction. Keep in mind that allergens can withstand heating and drying and exposure to small amounts of allergen is enough to result in anaphylaxis. Saliva, whether from a person or a pet can contain allergens and therefore can be a source of cross contact. For this reason sharing of anything that goes in the mouth can become a source. If students have contact with pets, keep in mind that pet food can contain allergens. Preventing cross contact with cleaning is important. Establish a cleaning protocol to avoid cross contact.
