(FOX News) -- For millions of American kids, collecting candy on Halloween night is a thrilling event. Nevertheless, the festivities can be complicated, and disheartening, for trick-or-treaters with food allergies.
According to the Food Allergy Research & Education (FARE) organization, 5.9 million children under age 18, or 1 in 13 kids, suffer from food hypersensitivities. In response, FARE launched a campaign three years ago that lets homeowners easily signal the trick-or-treaters with food allergies, telling them it's safe to visit. Dubbed the "Teal Pumpkin Project" -- as teal is the official color for food-allergy awareness -- people are simply leaving teal-painted pumpkins on their porches to let youngsters know they've got non-food or allergy-friendly treats to offer.
"It's clear that food allergies are a serious public health issue that we all must take seriously. The Teal Pumpkin Project provides an opportunity for all of us to show empathy for kids who often feel excluded," FARE's chief advancement officer Lois Witkop said in a statement.
"It's a terrific way for communities to come together and we would love to see at least one teal pumpkin on every block," she added.
Since its inception, the Teal Pumpkin Project has rocketed in popularity, with over 18,000 households from all 50 states participating in 2016, FARE said. Further, kids with medical conditions that limit their food options also benefit from the inclusive holiday fun.
