When you use a consumer product, it is your responsibility to ensure that it is safe for you to use. Many of the food allergens that can cause uncomfortable and harmful reactions can also be found in non-food products. Although you do not eat these products, you can still suffer an allergic reaction just by coming into contact with them.
In December 2016, Fairway Market of New York announced its recall of its store brand candy corn because the product could contain egg, despite the packaging not stating this. So far, one individual has reported suffering an allergic reaction from consuming Fairway candy corn. Individuals with egg allergies who have purchased this product are advised to return it to the store for a refund or throw it in the trash.
