(NBC News) - There's a push this year to add a different kind of Halloween decoration to the front of your house: A teal pumpkin.

started the "Teal Pumpkin Project." 

“Food allergies are potentially life-threatening. When we are looking at a Halloween celebration, it is really nice to provide something that is safe,” says Veronica LaFemina, spokeswoman for FARE.

LaFemina says that one in 13 children in the United States has a food allergy.

“The Teal Pumpkin Project encourages people to raise awareness of food allergies by providing non-food treats and painting a pumpkin teal … [which] indicates that house has non-food treats,” she says. Teal is the color for food-allergen awareness.

FARE recommends that families hand out stickers, glow-sticks, vampire teeth, bouncy balls, or spider rings instead of candy, which frequently contain allergens.

A teal pumpkin on your doorstep will signal you have treats like vampire teeth and spider rings instead of candy, which may contain allergens.

Allergy experts say smaller, bite-size versions of normally safe candy are sometimes manufactured differently, making them potentially dangerous for kids with food allergies.

The teal pumpkin is a sign that even at the scariest houses kids with food allergies won't be haunted by the treats inside.

An estimated six million children in this country have a food allergy.
